White lines printing through black text, primarily at bottom and top of page

[Davidl98]

I have currently ran into an issue where my printer is printing white lines or nothing at all, mostly at the tops and bottoms of pages. This has ranged from the top left corner of the page being a white block, to giant blocks of text missing at the top and bottom of pages, and also having faded and choppy lines. I also notice its only with black text, as you can see by the attached alignment page that the colored parts still appear normally. I have just recently changed the cartridge and that did not fix the problem. I also did a hard reboot and still nothing. I also went through all the cleaning and smudge jobs that are possible from the printer itself. I am at a loss for how to fix this issue. Also as a not I have tried reprinting the alignment page after every fix I tried and it still prints this same way every time.

@Davidl98,

Welcome to HP Forums, 

This is a great place to get support, find answers and tips to your technical queries.

To provide you with an accurate solution, I'll need a few more details:

Are you using genuine HP Ink cartridge?

I suggest you do a Hard Reset

(1) Turn the printer on, if it is not already on.

(2) Wait until the printer is idle and silent before you continue.

(3) With the printer turned on, disconnect the power cord from the rear of the printer.

(4) Unplug the power cord from the wall outlet.

(5) Wait at least 60 seconds.

(6) Plug the power cord back into the wall outlet.

NOTE: HP recommends connecting the printer power cord directly to the wall outlet.

(7) Reconnect the power cord to the rear of the printer.

(8) Turn on the printer, if it does not automatically turn on.

The printer might go through a warm-up period. The printer lights might flash, and the carriage might move.

Wait until the warm-up period finishes and your printer is idle and silent before you proceed.

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.

   

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.

    1. Insert the ink cartridge

    2. Close the lid

    3. The color ink cartridge is on the left, and the black ink cartridge is on the right

15. Repeat these steps to clean, then reinsert the other ink cartridge.

16. Close the ink cartridge access door.

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
