HP Designjet T1100 and T1120 MFP Series Products - Scanner cleaning, camera alignment, and calibration procedures

Scanner cleaning, camera alignment, and calibration procedures

Clean the scan area
  1. Turn the scanner power off and disconnect the scanner power cable.Location of power connection
  2. Open the scanner cover.
    • Push down on the two lever buttons found near the insertion slot on each side of the scanning area lid. The scanning area lid locking mechanism should now be disengaged.
  3. As you hold both lever buttons down, place your free fingers in the insertion slot and flip the scanning area lid open.Scanner lid
  4. The scanning area is now exposed for cleaning.
  5. Gently wipe the glass plate. Clean the glass with a lint-free cloth and a mild, streak-free, glass cleaner.
      caution:
    Do not use abrasives, acetone, benzene, or fluids that contain these chemicals. Do not spray liquids directly onto the scanner's glass plate or anywhere else in the scanner.
      caution:
    The lifespan of the glass plate depends on the paper types that pass across it. Abrasive papers such as mylar may cause premature deterioration, in which case the replacement of the plate is the customer's responsibility.Clean glass plate
  6. Dry the glass completely using a separate clean, dry lint-free cloth like the one provided with the maintenance kit.
  7. Clean the white background platen.
    The pressure-platen with the white-background-platen (white metal area) is fixed in the scanning area lid. Hold the lid open as you clean. Warning - do not attempt to remove the white background platen for cleaning it. Removing the white background platen is only necessary when replacing it.
    Wipe the white area with a lint-free cloth and a mild, streak-free, glass cleaner. Apply the cleaner to the cloth and first and then wipe the platen’s white area.

    Now continue with the Camera alignment and calibration procedure.
Camera alignment and calibration
Before you align and calibrate the cameras, make sure that you have gone through the first process in scanner maintenance: cleaning the scan area. An unclean scanning area will give you imprecise calibration results.
Camera alignment and calibration is a fully automatic process that you only need to activate through the wizard and then leave to run on its own.
  1. Connect the scanner power cable.Power cable
  2. Turn on the scanner.Power button
  3. The scanner should be warm.
    Make sure that the scanner has been turned on for at least one hour prior to camera alignment and calibration. Slight light intensity changes and camera shifting can occur just after turning the scanner on and the warm-up time will ensure that light conditions and camera heights have stabilized.
  4. Select the Setup tab.Setup tab
  5. Press the Options button. Select Scanning.Options tab
  6. Press the Scanner Maintenance button to start the Scanner Maintenance wizard.
    The maintenance wizard will guide you step by step through the whole maintenance process: Camera Alignment, Stitching, and Calibration.
  7. Insert the Maintenance Sheet that came with your system.Maintenance Sheet
    The wizard will ask you to insert the Maintenance Sheet that came with your scanner. The sheet's printed side must be inserted face down. Align the midpoint arrow with the scanner's midpoint arrow and feed the sheet into the scanner.
  8. When maintenance is completed, remove the Maintenance Sheet from the scanner and return it to its protective cover and then place it in the storage folder. Store the folder in a dry place and out of direct light.
