HP Photosmart C4200, C4400, C4500 Printers - Uneven Darkness in Black Text

This document is for HP Photosmart C42xx, c44xx, and C45xx All-in-One printers.
The quality of the black text or solid black figures on a document is not expected. The procedures in this document should help with uneven or non-uniform darkness.
Figure : Example of uneven darkness in black text
Image: Example of uneven darkness in black text.

Step 1: Use genuine HP ink cartridges

HP recommends that you use genuine HP ink or toner supplies. HP cannot guarantee the quality or reliability of non-HP or refilled cartridges. If you do not use genuine HP cartridges, the steps in this document might not resolve the issue. To check the authenticity of your cartridges, go to the HP anti-counterfeit webpage (in English).
Purchase replacement cartridges and other supplies from the HP Store or local retailers.
note:
Rough handling at the store or during installation can cause print quality problems with newly installed ink cartridges. If you see print problems with newly installed ink cartridges, wait for a few hours for the automatic servicing routine to complete, and then try to print again.
If using genuine HP ink cartridges did not resolve the issue, continue to the next step.

Step 2: Check the estimated ink levels

Low ink levels can affect print quality. Check the estimated ink levels from the printer software on your computer.
note:
The printer can detect the ink levels for genuine HP ink cartridges only. The ink levels in ink cartridges that are refilled or have been used in other devices might not register accurately.
  1. In the HP Solution Center, click Settings, point to Print Settings, and then click Printer Toolbox.
    note:
    You can also open the Printer Toolbox from the Print Properties dialog box. In the Print Properties dialog box, click the Services tab, and then click Service this device. The Printer Toolbox appears.
  2. Click the Estimated Ink Levels tab. The estimated ink levels for the ink cartridges displays.
    Figure : Example of Estimated Ink Levels
    Image: Example of Estimated Ink Levels.
  • If the black ink cartridge does not display a low ink level, you do not need to replace the ink cartridge yet. Continue to the next step.
  • If the black ink cartridge displays a low ink level, replace the ink cartridge, and then print. If replacing the critically low or empty ink cartridge did not resolve the issue, continue to the next step.

Step 3: Clean the ink cartridges

Cleaning the ink cartridges might improve print quality. Clean the ink cartridges from the printer control panel, and then evaluate the results.
note:
To avoid issues that require cleaning, always turn the printer off with the Power button.
  1. Open the Printer Toolbox. There are two ways to do this:
    • Open HP Solution Center, select the Settings menu, then the Print Settings submenu, and finally the Printer Toolbox.
    • If the HP Solution Center method does not work, open Printers and Faxes in the Windows Control Panel, then right-click your printer icon and choose Properties. Click Printing Preferences. Click the Services tab, then the Service This Device icon.
  2. The Printer Toolbox opens. On the Device Services tab, click Clean the Print Cartridges, and then follow the on-screen instructions. Up to three levels of cleaning are available. Discard or recycle the page that prints.
Try to print. If cleaning the ink cartridges did not resolve the issue, continue to the next step.

Step 4: Clean the contacts

If the preceding steps did not solved the problem, clean the electrical contacts on the ink cartridge and in the carriage in the printer.
  1. Gather the following materials:
    • Long, lint-free cotton swabs
    • A clean, lint-free cloth, or any cloth that does not come apart or leave fibers
    • Distilled, filtered, or bottled water (tap water might damage the printer)
  2. Open the printer lid and wait until the carriage is idle and silent.
  3. Remove the ink cartridge and place it on a piece of paper with the nozzle plate facing up.
    note:
    If you are removing a tri-color, photo, or gray photo ink cartridge, try to clean the contacts quickly enough that the ink cartridge is not outside of the printer for more than 30 minutes. The ink can dry and clog the nozzles if the ink cartridge is outside of the printer for too long.
  4. Disconnect the power cord from the rear of the printer.
  5. Disconnect the USB, if it is connected.
  6. Dip a swab in the clean water, then squeeze it to remove most of the moisture. The swab should be only slightly damp.
  7. Clean the ink cartridge contacts. Do not touch the nozzles.
    Figure : Ink cartridge electrical contacts
    Image: Ink cartridge electrical contacts.
  8. Clean the contacts in the print carriage, inside the printer.
    Figure : Carriage contacts
    Image: Carriage contacts.
  9. Either let the ink cartridge sit for ten minutes to allow the cleaned area to dry, or use a new swab to dry it.
  10. Reinstall the ink cartridge, plug the printer back in, and close the printer cover.
Try to print. If cleaning the contacts did not resolve the issue, continue to the next step.

Step 5: Remove the black ink cartridge and clean the ink nozzles

This problem might be caused by sediments collecting in the nozzle area on the black ink cartridge.
note:
The procedure below does not fix missing lines or streaked bars printed by the tri-color, photo, or gray ink cartridges, or other color printing problems. Only perform the steps below if the black ink cartridge has printed defective patterns, or if you notice non-uniform black text darkness.
  1. Remove the black print cartridge.
  2. If the carriage has a latch, re-latch it and then close the printer.
      caution:
    If the printer is not closed, it cannot adequately protect the remaining tri-color ink cartridge.
  3. Place the ink cartridge on a level surface with the nozzles up (label down).
    Figure : Ink cartridge with the nozzles up
    Image: Ink cartridge with the nozzles up.
  4. Allow the ink cartridge to sit undisturbed for two hours.
  5. Reinstall the ink cartridge and print another diagnostic page.
    1. Load letter or A4 unused plain white paper into the input tray.
    2. Press and hold the Cancel button and then press the Start Copy Color button.
    3. Make sure the test patterns show a complete grid and the thick color lines are complete.
    • If more than a few lines in a pattern are broken, this might indicate a problem with the nozzles. You might need to clean the ink cartridges.
    • If the black line is missing, faded, streaked, or shows lines, this might indicate a problem with the black ink cartridge in the right slot.
    • If any of the color lines are missing, faded, streaked, or show lines, this might indicate a problem with the tri-color ink cartridge in the left slot.
  6. Look for defects on the page.
    If the diagnostic page shows no defects for the black cartridge, and if the cartridge was new, align the cartridge. To align the cartridge, follow the steps below:
    1. Load letter, A4, or legal unused plain white paper into the input tray.
    2. In the HP Solution Center, click Settings, point to Print Settings, and then click Printer Toolbox.
      note:
      You can also open the Printer Toolbox from the Print Properties dialog box. In the Print Properties dialog box, click the Services tab, and then click Service this device.
      The Printer Toolbox appears.
    3. Click the Device Services tab.
    4. Click Align the Print Cartridges and an ink cartridge alignment sheet is printed.
    5. Load the ink cartridge alignment sheet print side down on the right front corner of the scanner glass.
    6. Press the button next to OK to scan the sheet.
    7. When the On button stops flashing, the alignment is complete and the page can be removed. Recycle or discard the print cartridge alignment sheet.
Try to print. If cleaning the ink nozzles did not resolve the issue, continue to the next step.

Step 6: Check the ink cartridge warranty

If you have a defective cartridge or printhead, it might be under warranty. To check the warranty on your ink or toner supplies, go to Printer and Page Yield Overview, and then review the limited warranty information for your supplies.

Step 7: Replace the problem ink cartridge

If the issue has not been resolved by these steps, the ink cartridge might be defective.
  1. Make sure the product is turned on.
      caution:
    If the product is turned off when the cartridge door is opened to access the cartridges, it will not release the cartridges for changing. The product might be damaged if the cartridges are not docked safely when trying to remove them.
    A prompt displays on the control panel display of the All-in-One to indicate that the cartridge is low on ink and will need to be replaced soon.
  2. Open the cartridge door.
    The carriage moves to the right side of the product. Wait until the carriage is idle and silent.
    Figure : Opening the cartridge door
  3. Lightly press down on a cartridge to release it, and then pull the cartridge toward you out of its slot.
    • If replacing the tri-color cartridge, remove the cartridge from the slot on the left.
    • If replacing the black or photo cartridge, remove the cartridge from the slot on the right.
  4. Remove the new cartridge from its packaging and, being careful to touch only the black plastic, gently remove the plastic tape by using the pink pull tab.
    Figure : Removing the tape
      caution:
    Do not touch the copper-colored contacts or ink nozzles. Also, do not re-tape the cartridges. Doing so can result in clogs, ink failure, and bad electrical connections.
  5. Hold the cartridge with the HP logo on top, and insert the new cartridge into the empty cartridge slot.
    • If installing the tri-color cartridge, slide it into the left slot.
    • If installing a black, photo, or gray photo cartridge, slide it into the right slot.
    Figure : Inserting the cartridges
  6. Push the cartridge firmly into the slot until it snaps into place.
  7. Close the cartridge door.
Try to print. If replacing the problem ink cartridge did not resolve the issue, continue to the next step.

Step 8: Service the printer

If you have followed all the steps in this document and your printer continues to produce printouts with print quality issues, service the printer.
note:
Keep a print sample that shows the problem. If the ink cartridges, printhead, or printer is replaced under warranty, the support agent will request the print sample. If the printer is returned to HP, the print sample must be returned with the printer. Place the sample in the output tray when you package your printer for shipping.
Service or replace your HP product if the issue persists after completing all the preceding steps.
Go to Contact HP Customer Support to schedule a product repair or replacement. If you are in Asia Pacific, you will be directed to a local service center in your area.
To confirm your warranty status, go to HP Product Warranty Check. Repair fees might apply for out-of-warranty products.
