Poor Print quality for black cartridge

HP Recommended
Android 8.0 Oreo and older

Hello everyone.

 

Printer model: HP ENVY 4520

 

1) I had no printing both for trichromatic and black cartridge. I noticed that the trichromatic one was almost ended, so I replaced it. The black was about at ⅓ of the full capacity, so I held it.

 

2) After this operation, I'm facing the new problem that now the printer works well for colour characters, but gives very poor quality for black ones, that is, for instance, the alphabetical characters are represented only in their edges, hence internally they remain white. Please look at the below picture to get an idea. This happens on both Android and Ubuntu platforms.

 

[3) I had preliminarily done the cleaning of  the black cartridge, and alignment of both ones.]

Welcome to the HP support community.

 

Manually clean the area around the ink nozzles

  1. Gather the following materials:

    • Dry foam-rubber swabs, lint-free cloth, or any soft material that does not come apart or leave fibers (coffee filters work well)

    • Distilled, filtered, or bottled water (tap water might contain contaminants that can damage the ink cartridges)

         CAUTION: 

      Do not use platen cleaners or alcohol to clean the ink cartridge contacts. These can damage the ink cartridge or the printer.

  2. Turn on the printer, if it is not already on.

  3. Gently grasp the handles on either side of the printer, then raise the ink cartridge access door until it locks into place.

    The carriage moves to the center of the printer.

  4. Wait until the carriage is idle and silent before you continue.

  5. Disconnect the power cord from the rear of the printer.

  6. Disconnect the USB cable, if it is connected.

  7. To release the ink cartridge, lift the lid on the ink cartridge slot, then gently push the lid back until it stops.

  8. Pull up on the ink cartridge to remove it from the slot.

       CAUTION: 

    Do not remove both ink cartridges at the same time. Remove and then clean each ink cartridge one at a time. Do not leave an ink cartridge outside the printer for more than 30 minutes.

    1. Lift the lid

    2. Gently push the lid back

    3. Pull up on the ink cartridge

  9. Hold the ink cartridge by its sides.

       CAUTION: 

    Do not touch the copper-colored contacts or the ink nozzles. Touching these parts can result in clogs, ink failure, and bad electrical connections.

    Image: Do not touch the contacts or nozzles.

  10. Lightly moisten a foam-rubber swab or lint-free cloth with distilled water, and then squeeze any excess water from it.

  11. Clean the face and edges around the ink nozzle with the swab.

       CAUTION: 

    Do not clean the ink nozzle plate.

    1. Nozzle plate - Do not clean

    2. Area surrounding ink nozzle - Do clean

    3. Ink cartridge contacts - Do not clean

  12. Either let the ink cartridge sit for 10 minutes to allow the cleaned area to dry, or use a new swab to dry it.

  13. Hold the ink cartridge by its sides with the nozzles toward the printer, then slide the ink cartridge forward into the slot.

  14. Close the lid on the ink cartridge slot to secure the ink cartridge into place.

  17. Reconnect the power cord to the rear of the printer.

  18. Turn on the printer, if it does not turn on automatically.

  19. Try to print again, and examine the page.
