HP Designjet T1100 MFP, 4500mfp, 4500 Scanner, 820 MFP - Scanner Adjustments and Calibrations

Introduction
This chapter explains how to adjust the scanner for optimal scanning-quality. It describes the adjusting procedures in detail and provides additional information regarding acceptance criteria.
A general concept when adjusting the scanner is to loosen screws just slightly. If you loosen the screws too much, you will have difficulties controlling the adjustments, because of too much play in the adjustment levers and other adjustment points. Unless this chapter states otherwise, always loosen screws and nuts only slightly. They should be snug; there should be no play when you try to wiggle them. When tightening a set of screws, tighten all of them little by little, rather than fully tightening one, and then another, and so on.
Tools Required
To perform the Camera Adjustment you will need:
  • Focus Adjustment Pattern sheet (included in the Service Patterns pn Q1277-60030).
  • Optical Adjustment Pattern (pn Q1277-60031).
  • Torx 10
  • Torx 20
To perform the Sensor Adjustments you will need:
  • Adjustment Tools for ATAC Sensors (Q1277-60084).
  • Torx 10

Camera Design Overview
Introduction
The HP Designjet scanner uses 3 cameras, where each camera scans its own part of the image.
The cameras are named A, B and C. Camera A is on the right and Camera C is furthest to the left. The cameras scan-area overlaps slightly, this is to ensure that the scanner scans the complete image. Most of the scanner adjustments are focused on getting the correct Scan- Width. The adjustment ensures that a camera scans the right amount of image data so that the basic DPI resolution of the camera is precise. This fine-tunes the accuracy of the scanner. A metal wire (stitching wire) in the overlapping area helps the scanner to adjust the cameras electronically. The following picture shows what the camera actually looks like. Only Camera A and C have a motor at the rear (Camera B does not have a motor).
The CCD Element
The central component of the Camera is the Sony CCD (Charge Coupled Device) element, which is responsible for capturing the colors reflected from the original image.
The CCD is formed as a chip, and is inserted into a standard dual in-line socket just like a normal chip. The chip has 4 rows each containing 7500 pixels.
The 4 rows each scan a different color. Combined, the 3 rows provide 24 bit color. The last row is for panchromatic scanning. Each CCD pixel is formed as a square with a side length of 5 μm. There is 40 μm between the adjacent lines.
Camera Board Adjustments
The Scan-Width Adjustment Screw moves the camera backwards and forwards, which influences the Scan-Width of the camera.
When the Scan-Width Screw is screwed in, as illustrated on the left side of the above picture, the camera has a greater possible scan-width. When it is screwed out (right side of picture), the camera has a smaller possible scanwidth.
The Scan-Width Screw is fixed on the camera assembly and not on the scanner chassis. This means, that when screwing the screw backwards, you have to loosen two T15 screws and push the camera forward manually to decrease the scan-width. When screwing forward, the screw will push the camera backwards on it’s own.
The CBE Camera Board, where the CCD is placed, can be moved relative to the camera using 3 adjustment levers.
This is an easy and quick way of adjusting the camera, as it does not involve moving the camera itself, but only the camera board, which can be done very precisely.
  • Vertical Tilt – Left: moves the left upper edge of the CCD Mounting Plate and the CBE Camera Board up and down, making the field of vision tilt in proportion to the horizon.
  • Vertical Tilt – Right: moves the right upper edge of the CCD Mounting Plate and the CBE Camera Board up and down, making the field of vision tilt in proportion to the horizon.
  • CCD Centering: moves the CCD Mounting Plate and the CBE Camera Board horizontally left and right and thereby making the field of vision move horizontally left and right.
The camera itself can be tilted up and down which causes the field of vision to move up and down. The Vertical Positioning Hexagonal Nut is used for coarse adjustments and the Tilt Levers are used for finer adjustments. When you rotate the Vertical Alignment Hexagonal Nut counter-clockwise you raise the camera and the field of vision and vice versa.
To rotate the Vertical Positioning Hexagonal Nut use the adjustment tool which comes with the Camera B, the tool is shown mounted on the side of the camera in the grapic on the previous page.
When using the Vertical Positioning Hexagonal Nut , loosen the Lock Screw first, so that the Vertical Alignment Arm doesn’t move simultaneously. You will normally not adjust directly on the Vertical Alignment Screw, but instead via an extension and through a hole in the scanner front.
Adjusting the Camera Using Manual Procedure
This Chapter explains how to adjust Camera A manually using oscilloscope sofware which comes with the scanner. In this procedure we focus on Camera A, but the procedure is exactly the same for Cameras B and C.
It is important that you use this procedure (Test 9) to manually adjust the camera and NOT the Camera Adjustment Wizard (Test 27).
Light Profile
Make sure that the left and right covers are installed and the top cover is removed. The scanner and the touch screen must be switched ON.
When you install a camera in the scanner for the first time, the camera is completely out of adjustment. If you get an Error 30 from SCANtest when setting the Light Profile to Corrected, start with Uncorrected and follow steps 3 and 4 as well as you can and then start over with the Corrected Light Profile again.
The first thing to be done before adjusting the camera that has been replaced is to ensure that the camera is at least looking in the right direction.
  1. Make sure that camera is completely installed and all cables are correctly connected.
  2. Select button 9. Camera Adjustment in SCANtest 6.
  3. A software oscilloscope is now activated and looks something like this:
  4. You see the uncorrected light profile, for Cameras A, B and C that the scanner receives from the reflection of the White Background on the back of the Guide Plate. Camera A is on the left, Camera B is in the middle and Camera C is on the right. You can zoom in with the buttons on the touch screen. You can see that the output is lower at the edges. This is because of the lens in the camera. If you get a screen that looks distorted in comparison with the above image, then maybe your camera is looking into the chassis instead of the mirrors in the copier. To correct this, use the tool to rotate the Vertical Alignment Screw located underneath the camera, rotate the screw left or right until you get an oscilloscope image similar to the one shown.
Focus Adjustment
The first adjustment that you need to make is the focus. This adjustment ensures, that the camera has the right focus, so that the following adjustments aren’t blurred out. The focus setting is not as sensitive as some of the other adjustments, which makes it a good example to start with. When you are finished with all the adjustments, you should check the focus again just to be sure that it’s still OK.
  1. Stay in the Software Oscilloscope and select Corrected and then press the Execute button. Only adjust the focus in the corrected mode. Make sure that the Blue color channel is selected.
  2. Wait approximately 90 seconds until SCANtest 6 is ready.
  3. Insert the Focus Pattern in the scanner.
    It’s best to insert the sheet from the back of the copier and use the Reverse Key to position the pattern correctly. This way the sheet won’t cover the cameras when you adjust them. It requires a little practice but makes the focus adjustment a lot easier.
    Use the operation panel keys to move the sheet so that the cameras see the 3.33 lp/mm pattern.
  4. Loosen the Focus Lock Screw and turn the Lens Adapter to adjust the focus.
    The Focus adjustment greatly influences the Scan-Width. Therefore, the Scan- Width must be checked and readjusted whenever the Focus adjustment has been changed.
    The Focus adjustment, however, is realatively tolerant to Scan-Width adjustments. After adjusting the Scan-Width, check the Focus adjustment again; it will only need further adjusting if the Scan-Width has change greatly. However, you should check both the Focus and the Scan-Width after an adjustment to either to ensure that they are both correctly adjusted.
    Loosen the Focus Lock Screw and ensure that it is not too loose. Turn the Lens Adapter until you get this picture on the software oscilloscope.
    (Camera A has been zoomed in):
    The signal has to be as even as possible and especially the ends have to be at their highest possible level.
    When the focus is right, tighten the Focus Lock Screw.
    Keep in mind that if you adjusted the Focus, the Scan-Width has changed and must be adjusted.
    There is a mark on every lens, which indicates its “best position”. If you have completed the focus adjustments and this mark isn’t pointing upwards, mark the upward position on the Lens Adapter. Turn the Lens Adapter and loosen the Focus Lock Screw and the three Lens Fixing Screws (with a 1,5 mm Allen key). Then turn the Lens so that the mark is pointing upwards, tighten the Lens Fixing Screws again. Turn the Lens Adapter back again and check that the focus it still correct before tightening the Focus Lock Screw.
Scan-Width Units
When adjusting the Scan-Width, you adjust up against some line on an Optical Adjustment Pattern.
The Optical Adjustment Pattern is a metal construction with a pattern glued on one side. This pattern contains three sub-patterns: A, B and C.
  • Sub-pattern A contains a pattern used for Scan-Width adjustment.
  • SSub-pattern B contains a pattern used for Vertical Position adjustment.
  • Sub-pattern C contains a pattern used for coarse Focus adjustment.
The A part of the pattern consists of scan-width units (SWU).
Each of the black lines represents a scan-width unit (SWU) as does the white space in between the lines. This makes a total of seven SWU’s.
The black lines and whites spaces work like a marker or indicator that tells you how wide the camera scan-width is.
The scan-width units help you adjust the cameras, so that they have the correct scan-width. This ensures that the scanner has the correct optical resolution. Thereby ensuring that the scaling factor of the scanner is correct.
Camera A has three A patterns in its view:
To ensure that the camera has the correct optical resolution, you are going to adjust the camera, so that it covers six scan-width units. This means that the camera has to see a total of six units at the ends of the view field. This can be two on the left and four on the right or five on the left or one on the right. The unit arrangement is not important as long as there are six in total.
Later on you will center the camera, so that there will be three units at each end.
Scan-Width Adjustment
The purpose of Scan-Width adjustment is to position the camera so the field of vision is correct.
  1. Open the Guide Plate and place the Optical Pattern on the scanner. Align the pattern by pressing it to the right towards the operator panel and backwards toward the back of the scanner.
  2. If not selected, select button 9 in SCANtest 6. Select Uncorrected Light Profile and press Execute (make sure that the Green Channel is selected).
  3. This is what Camera A is going to see, when the scan-width adjustment is finished:
    Camera A scans from right to left, so the image above is a mirrored section of the total Scan-Width pattern as the copier actually sees it. The camera only sees a single line of pixels with the green CCD pixel line that we enabled under step 2. The goal is to adjust the camera so that the green pixel line of the CCD is positioned as the green line below:
    When you have succeeded in getting this, most of the adjustments for Camera A are finished.
    If the scan width changes by more than one scan-width unit (SWU), you must check the focus.
    But first we start by setting the Scan-Width of Camera A. You use the software oscilloscope to guide you, and this is what you are going to see:
    In the image you see a real oscilloscope image of the left- and the right most part of the Camera A Scan-Width pattern. Whenever the camera sees a black line, the output level goes down. It goes up when seeing white. When the Green CCD Scanline is in the correct position, each end of the camera output will have the appearance as shown.
  4. Now press Scan Width under Detail View on the software and the program automatically zooms in on the left and right part (Scanline Start/End) of the output. On the left side you will get an output like one of these (or something in between):
    The output we are aiming for can be seen below, therefore:
    • The left output is too much to the left – if you have an output like this, you need to slide the CCD board to the right by turning the CCD Centering tab upwards.
    • The right output is too much to the right – if you have an output like this, you need to slide the CCD board to the left by turning the CCD Centering tab downwards.
  5. When you have one, two or three scan-width units (SWU) on the left side of the camera, look at the right side of the camera.
  6. On the right side (Scanline End) you will get output like one of the following:
    Remember how many scan-width units you had on the left side and remember that there has to be six in total.
    If you had three SWU’s on the left side of the output you also have to have three on the right and the output we are aiming at is as shown below. Therefore:
    • On the left picture above the Scan-Width is too wide – if you have an output like this, you need to move the camera forward to decrease the Scan-Width.
    • On the right picture above the Scan-Width is too narrow - if you have an output like this, you need to move the camera backward to increase the Scan-Width.
    Look for the Stitching Wire. There’s only one of these on the right side of the camera. If you don’t see the Stitching Wire, then the camera has to be pulled back quite a lot because the scan-width is too narrow.
  7. Repeat steps 4 to 6 until the camera sees a total of six SWU’s.
  8. When you have six SWU’s in total, use the CCD-Centering lever to adjust the camera so that there is three SWU’s on each side of the camera as shown below:
  9. Check the focus again because large changes to the Scan-Width adjustment also affects the focus.
  10. If the focus needed adjusting, start over with the Scan-Width from step 4, because a slight change in the focus will affect the Scan-width considerably.
  11. When you are finished, and both the focus and the Scan-Width are correct, tighten the three Camera Fixing Screws without moving the camera.
  12. Proceed to the Vertical Positioning section without altering anything about your set-up.
Vertical Positioning
The purpose of the vertical positioning is to adjust the camera, so the Green CCD Scanline looks at the correct vertical position on the Optical Adjustment Pattern as seen on the picture below. Furthermore it ensures that the Scanline is horizontal.
  1. SCANtest 6 should still show Uncorrected Light Profile, Green. If not, change it to those settings.
  2. Loosen the Camera Back-Plate Fixing Screws if they are not already loose.
  3. Select Vertical Positioning under Detail View and look at the left part (Scanline Start) of the camera output. You will get an image similar to one of these (or even less lines than shown on the right image):
    The output we are aiming for can be seen below, therefore:
    • On the left image the vertical position is too low – if you have an output like this, you need to lower the left side of camera with the left Vertical Tilt lever, by turning to the left.
    • On the right image the vertical position is too high - if you have an output like this, you need to raise the left side of camera with the left Vertical Tilt lever, by turning it to the right.
  4. When you have adjusted the Vertical Tilt so that the output displays 8 black lines (your output does not have to be identical to the above picture or the Reference Image, just close) on the left side of the camera, look at the right side of the camera.
  5. On the right side (Scanline End) you will get an output similar to one of these:
    The Vertical Tilt lever can’t be moved very far before it loses its grip. If this happens while you are adjusting the camera, move the Vertical Tilt levers back to the middle position and use the Vertical Position Pre-Set Screw to make a coarse adjustment. Then fine tune again with the Vertical Tilt lever.
    When adjusting the Vertical Position, you continuously have to readjust the CCD Centering (3 scan-width units) with the CCD Centering lever, because the Vertical Tilt lever moves the camera a little in the horizontal direction.
    The output we are aiming for can be seen below, therefore:
    • On the left image the vertical position is too low – if you have an output like this, you need lower the right side of camera with the right Vertical Tilt lever, by turning downwards.
    • On the right image the vertical position is too high - if you have an output like this, you need raise the right side of camera with the right Vertical Tilt lever, by turning it upwards.
    When you have adjusted the Vertical Tilt so that the output displays 8 black lines and 4 smaller lines (it doesn’t have to be precise, just close to the above picture) on the right side of the camera, look at the left side again to check that it’s still okay (it’s probably not). It very likely that you have to go back and forth between left and right a couple of times until both sides are adjusted the right way. That is because adjusting one side affects the other side a little.
  6. Check that the CCD Centering is OK. That is that you still have 3 SWU’s on each side of the Camera. If you don’t then adjust it with the CCD Centering Lever.
  7. Tighten the Camera Back-Plate Fixing Screws gently to prevent the camera from moving out of adjustment.
  8. Once the cameras are adjusted, you will need to adjust the whole scanner to fine-tune it by performing the Scanner Maintenance.
Adjusting the Camera Using the Camera Wizard
Preparing the Scanner
Before you start make sure that you have the following items, which are necessary to complete the Camera Adjustment:
  • The SCANtest6 is installed in the touch screen (programs - Scanner Test Program - Scantest 6).
  • Focus Adjustment Pattern sheet (included in the Service Patterns pn Q1277-60030).
  • Optical Adjustment Pattern (pn Q1277-60031).
Make sure that the scanner you are adjusting is fully functional. If the scanner is not operational, you will not be able to adjust the camera.
Make sure that the left and right covers are installed and the top cover is removed. The scanner and the touch screen must be switched ON.
  1. Make sure that the cameras are all installed correctly and all cables are connected.
  2. Start SCANtest 6 and select: 27. Camera Adjustment Wizard.
  3. The Camera Adjustment Wizard will start with the welcome screen. Select next to contine.
  4. The screen will display the list of Service Tools necessary to complete the Camera Adjustment correctly. Select next to continue.
  5. The next 4 screens contain information on how to perform the camera Adjustment correctly. Select next after reading each screen.
  6. In order to validate the current state of the cameras you will need to open the Guide Plate and place the Optical Adjustment Pattern on the Scanner. Align the pattern by pressing it to the right towards the Operator Panel and backwards towards the back of the scanner. Once the cameras have been validated, select next to continue.
  7. The Scanner will now perform some internal adjustments. In order to do this you will need to remove the Optical Adjustment Pattern and close the Guide Plate.
  8. Once the internal adjustment has been done, you will need to insert the Focus Adjustment Pattern in the Scanner.
    It’s best to insert the left corner of the Focus Adjustment Pattern first and then slide the right side of the pattern in to place.
  9. Once the Scanner detects that the Focus Adjustment Pattern is correctly positioned you will be able to select next to continue.
  10. Select the camera that you need to adjust. Camera A is the one closer to the front panel.
  11. Remove the Focus Adjustment Pattern and place the Optical Adjustment Pattern on the Scanner. Align the pattern by pressing it to the right and backwards towards the back of the scanner. Once the pattern has been detected, select next to continue.
  12. In this example, the camera requires partial adjustment before completion. Loosen the 3 Camera Back-Plate Fixing Screws and then select next.
  13. Turn the Centering Lever until the arrow on the screen is in the center of the scale and the value is 0 (or as close as possible). Once the value is within tolerance, you will be able to select next to continue.
  14. Turn the Left and Right Vertical Tilt Levers until the horizon is level with the arrows. Also turn the Centering Lever so the center scale is 0 (or as close as possible). Once the value is within tolerance and the horizon is level with the arrows, you will be able to select next to continue.
  15. Tighten the 3 Camera Back-Plate Fixing Screws and then select next.
  16. Loosen the Camera Fixing Screws slightly so that the camera housing can be moved. Select next to continue.
  17. Turn the Scan-Width Screw until the arrow on the screen is in the center of the scale and the value is 6.0. Once the value is 6.0 (or as close as possible), tighten the Camera Fixing Screws while maintaining the correct adjustment. Once the screws are tightened, select next to continue.
  18. Loosen the Camera Back-Plate Fixing Screws slightly so that the camera housing can be moved. Select next to continue.
  19. Turn the Left and Right Vertical Tilt Levers until the horizon is in level with the arrows. Also turn the Centering Lever so the center scale is 0. Once the value is 0 (or as close as possible) and the horizon is level with the arrows, you will be able to select next to continue.
  20. Tighten the Camera Back-Plate Fixing Screws gently to prevent the camera from moving out of adjustment. The Camera Adjustment has now been completed.
  21. Perform the Scanner Maintenance to ensure that Color Calibration, Stitching and Vertical Alignment are correct.
Scanner Maintenance
Once the cameras are adjusted, you will need to adjust the whole scanner to fine-tune it by performing the Scanner Maintenance. Scanner Maintenance does the following three things automatically:
  1. Runs Vertical Alignment, which adjusts the vertical position of the Cameras.
  2. Adjusts the Stitching, which controls the overlap between the Cameras.
  3. Color Calibrates the Scanner to get optimal colors and gray tones.
Performing Scanner Maintenance
For this part of the adjustments you will need the following item:
  • Scanner Maintenance Calibration Sheet 42” (included in the Service Patterns pn Q1277-60030).
  1. Start by removing the Optical Adjustment Pattern, cleaning the scanning area, and then closing the Guide Plate.
  2. Exit the Camera Adjustment Wizard and exit SCANtest 6.
  3. Wait for the Scanner to reboot and then start Scanner Maintenance when only the green lamp is lit up on the scanner keyboard.
  4. Insert the Scanner Maintenance Calibration sheet and press Next two times.
  5. Wait for Scanner Maintenance to finish. It takes about 20 minutes.
  6. Remember to put the calibration sheets back into the original packing, so that they last longer.
ATAC Position Sensors check
This procedure is to check the sensors in the Original Guide come on when the media sensors are activated.
  1. Start SCANtest 6 and select Test 28, Original Guide Sensor Test
  2. If the guide plate is in the lowered position, press the UP Key on the scanner front panel to move the Guide Plate to the Top Position and observe that:
    • Ready LED is OFF
    • Wait LED is OFF
    • The Power LED turns green (Top Position Sensor activated)
  3. Move the Guide Plate down by pressing the Down Key on the scanner front panel and observe the LEDs in following sequence:
    • Power LED turns OFF
    • Wait LED turns yellow (Down Position Sensor* activated)
    • Ready LED turns green (Roller sensor activated)
*The Down Position Sensor cannot be adjusted.
Original Guide Sensor Test
This is to test the sensors which are located inside the Guide Plate.
Adjustment of the Roller Sensor
To perform this adjustment you will need the two Roller Sensor Adjustment tools.
  1. Perform the following:
    • Remove ruler from the front of the Guide Plate.
    • Open the Top Profile on the Guide Plate.
  2. Start SCANtest 6 and select Test 28. Original Guide Sensor Test
  3. Press the UP Key on the front panel of the Scanner to move the Guide Plate up until the Ready LED turns OFF.
  4. Loosen the two screws that secure the Roller Sensor.
  5. Using the 1.5 mm end of each of the two Adjustment Tools, insert them on both sides of the Roller Sensor under the roller shaft.
  6. Adjust the position of the Roller Sensor so that the green Ready LED just about turns ON.
  7. Using the 1 mm end of each of the two Adjustment Tools, insert them on both sides of the Roller Sensor under the roller shaft.
  8. Check that the green Ready LED is OFF.
  9. Tighten the two screws that secure the Roller Sensor.
Adjustment of Top Position Sensor
To perform this adjustment you will need the adjustment tool for the Top Position Sensor:
  1. Perform the following:
    • Remove the ruler from the front of the Guide Plate.
    • Open the Top Profile on the Guide Plate.
  2. Close and lock the Guide Plate.
  3. Start SCANtest 6 and select Test 28. Original Guide Sensor Test
  4. Loosen the four screws that secure the sensor bracket, move the sensor to its uppermost position and tighten the four screws.
  5. Press the UP Key to move the Guide Plate to the higest position.
  6. Open the Guide Plate.
  7. Orientate the two adjustment guides for 16 mm spacing and insert the guides under the Guide Plate at both ends of the scan area.
  8. Place the two adjustment guides so that the surface marked "16" is facing the White Background. To avoid possible damage to the White Background, place the cut-out centered over the light aperture of the glass plate.
  9. Close the Guide Plate and make sure that both Release Handles are locked.
  10. Press the Down Key to move the Guide Plate down until it automatically stops against the adjustment guides.
    If the Down Key is pressed after the Guide Plate has stopped, the MDA Board turns OFF and you need to power the scanner ON again.
  11. Loosen two screws that secure the Top Position sensor.
  12. Adjust the Top Position sensor so that the green Power LED just about turns ON.
  13. Tighten the two screws that secure the Top Position sensor.
