Officejet 7500A Wide Format Won't Print Black

HP Recommended
Officejet 7500A wide format
Microsoft Windows 7 (64-bit)

I am having the same problem as a few other recent people have posted...!


My printer stopped printing in black.  I use only HP ink, which just got new to try and fix this problem. 

Cleaned print heads and all other suggestions from earlier post ablout this model printer.

No luck.


What is going on here?  All of a sudden, HP seems to be having issues with this!


Have you figured it out just?  Or is this just a "bug" or money making technique.... so we have to buy new printers?


Help and a fix would be great!!!!

Thanks for taking an interest in the HP Support Forums After reading your post I see that you require assistance in printing in black. I will be a delight to assist you here. Superb analysis and brilliant diagnosis of the issue before posting. 🙂 Kudos to you on that score. 🙂


For better clarity and to assist you better I would require more information regarding this:

How did you clean the printhead from the printer, from the printer control panel or by manually removing the printhead out?




Make sure the ink cartridges are properly vented and seated correctly

  1. Open the ink cartridge access door.

    The carriage moves to the center of the printer.

  2. On the front of the ink cartridge, press the tab in to release it, and then pull it up and out to remove it from its slot.

  3. Examine the vent area on each ink cartridge, above the HP logo on the top of the ink cartridge.

  4. If the ink cartridge still has the orange pull-tab attached, pull to remove it.

  5. If the vent is clogged, use a straight pin to gently remove excess adhesive from the vent.

    3. Unclogged vent

  6. With the nozzle and the contacts facing down, slide the ink cartridge into its slot. Press down on the cartridge until it snaps into place. Make sure the color icon on the ink cartridge label matches the color icon on the slot.

  7. Repeat these steps to inspect the vents on each of the ink cartridges.

  8. Make sure each ink cartridge is firmly in place in its slot. Run your finger along the top of the ink cartridges to feel for any that are protruding, and if any are, press down firmly until each ink cartridge snaps into place.

  9. Close the ink cartridge access door.

  10. Wait until the printer is idle and silent before you proceed.

If you have not cleaned the printhead manually

When manually cleaning the printhead, the printhead nozzles are soaked in very warm water for no longer than ten minutes. Use these steps only as a last resort and if the printhead would be disposed of otherwise.


Manually cleaning the printhead should only be performed if the printhead is no longer under warranty.

  1. Set the pan on the stove, and then fill the pan with filtered or distilled water.


    Do not use alcohol or other solvents. This might damage the printhead, causing the printhead layers to separate, requiring replacement of the printhead.

  2. Heat the water until the water is very warm to the touch, but do not boil the water.

  3. Stack the paper towels at the bottom of the disposable container until the stack is about 6.5 mm (1/4 inch) deep.

  4. Pour the warm water from the pan into the disposable container so that it is 5 cm (2 inches) deep and covering the paper towels.

  5. Put on disposable gloves to prevent ink from transferring to your skin or clothes.

  6. Press the tab on the front of the ink cartridges to release them, and then lift the ink cartridges out of the printhead.


    Do not leave the ink cartridge outside the printer for longer than 30 minutes. The printhead and ink cartridges can be damaged by being exposed to air outside of the printer.

  7. Set the ink cartridges upside down on a paper towel.

  8. Lift the latch handle on the carriage until it stops, and then carefully lift up on the printhead to remove it from the printer.

    Figure : Removing the printhead

  9. Moisten one of the clean, lint-free cloths with some of the warm water and use it to clean the underside of the printhead. Repeatedly wipe the nozzle area gently until excess black or color ink does not transfer to the cloth. Do not press into the nozzle area as this can cause damage.


    Do not force water into the printhead, this can cause printhead delamination.

  10. Place the printhead into the disposable container so that the bottom rests on the paper towels, and then let it soak for 10 minutes.

    Figure : Soaking the printhead

    1. Paper towels

    2. Water level

  11. Remove the printhead, and then gently wipe the excess water with a dry lint free cloth.


    Do not use a hair dryer to dry off the printhead. This could cause the nozzles to dry out and clog.

  12. Let the printhead air-dry on a paper towel for 15 minutes with the nozzles facing up.


    Do not use compressed air to blow out the printhead. This can cause delamination of the printhead.

    Figure : Printhead drying with the nozzles up

    Image: Printhead drying with the nozzles up
  13. Lower the printhead into the carriage, and then carefully lower the latch handle.


    Make sure the colored shapes on the sides of the printhead line up with the colored shapes on the carriage.

    Figure : Lowering the latch handle

  14. With the ink cartridge contacts facing the printhead, slide the ink cartridge into the correct slot. The color-coded icons on the ink cartridge and in the printhead indicate the correct slot.

    Press down on the ink cartridge until it snaps firmly into place.

    Figure : Inserting the ink cartridge

    Image: Insert the ink cartridge.
  15. Repeat these steps for each ink cartridge.


If you encounter the 'Printhead Problem' error message, turn the printer off and back on again.

The automated printhead cleaning tool must run after manually cleaning the printhead.
