Black Ink not Printing

[cer4]

I have a HP 7520.

The black ink was not printing so I tried the cleaning module and then manually cleaned the heads.

I just put them back in and nothing happens.

The on/off button doesn't turn the machine on. Dead as doorbell.

Any thoughts?

Hi @cer4,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

I understand you're experiencing an issue with your printer that is not powering on.

I apologize for any inconvenience this may have caused, I'm here to help you today.

Please follow the steps below to fix the issue.

- Perform a power drain on the printer.

1) Take out the cartridges

2) Unplug the power cord from the printer & wall.

3) Press and hold the power button down for 15 seconds and release the power button, wait for about 30 seconds.

4) Plug the power cord back into the printer and wall outlet directly, ensure the printer is plugged into the wall & not into a surge protector.

5) Insert the cartridges back into the printer.

Remove the cartridges > Unplug the power cord > Wait for 30 seconds > Plug the power cord back in > Insert the cartridges

- Update the printer firmware by clicking on this link if the printer turns on.

- If the issue still persists, try with an alternate power cable that is compatible with your printer.

This worked and helped me get the printer started again.

Tjhe printer still is unable to print saying there is a problem with the printer or ink system.

My cleaning the printer head may have goofed things uo.

I've ordered a new printer head will see if replacing the printer resolves the problems

Hi @cer4,

Please installed the new printhead when it is delivered and let me know if that resolves the issue.

I will be archiving this case for now. However, you can respond to the same thread to continue the conversation.
