how to solve printhead failure

Hi @Jan171 

Welcome to the HP Support Community. We are here to help you with it.

Could you please follow the steps shared below and let me know the outcome of it?

A)

First, you can try a device reset, as follows:

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

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

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

Unplug the power cord from the wall outlet.

Wait at least 60 seconds.

Plug the power cord back into the wall outlet.

note:

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

Reconnect the power cord to the rear of the printer.

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

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

If these steps resolved the issue, you do not need to continue troubleshooting.

B)

If this doesn't help, I would recommend just removing the printhead, cleaning its socket and then reseating the printhead again.

C) 

In rare cases, the error can stem also from defective ink cartridges (not the printehead). In order to exclude the error cause coming from ink cartridges, you can remove all ink cartridges, and close the device, and wait till the device is idle. If then the error message changes, saying "no cartridges" (or similar), then the original error (Oxc19a0003) can stem from cartridges (instead of printhead). Proceed adding the first cardridge (only one!) in place, close the device, wait till it's idle and observe the error message. Add one-by-one the other cartridges, so you can find out, which cartridge is the culprit (defective). If the original error message (Oxc19a0003) persists unchanged even when ALL cartridges is taken out from the device, then the printhead is defective.

D)

If the error isn't caused by defective cartridges (as layed out in "C") then you should troubleshoot further according to this resource:
