I installed new HP black cartridge. Printer prints colors but no black.

HP OfficeJet Pro 8025e will no longer print black after installation of new black HP 910xl.

Color images still print OK.

None of the maintenance activities (cleaning head, etc.) resolve the problem.

Please advise.

If there are no error message from EWS or the control display, your printhead probably needs to be cleaned

See if EWS can provide more information about the problem.
This explains how to use the EWS
Use the HP printer Embedded Web Server (EWS)

This link shows cleaning the 8600 printhead and removal is shown here.

This is another type of printhead cleaning, different from the above.

Cleaning and removing ink is shown below by our "Scullery" team.

An HP original video on how to clean the printheads by our experts. Yes, this can get messy, but it works. If your ink levels are good but you are printing blank pages then this is likely the solution.

Official HP advice on cleaning.

Some printers have a printhead cleaning procedure.

To clean the printhead on an HP printer, access the printer settings through the HP Smart app, navigate to "Print Quality Tools," and select "Clean Printhead"; this will initiate a cleaning cycle where the printer will automatically run a cleaning process to clear any clogs in the printhead

Inkjet and printhead cleaning kits are available

Consumer inkjet printer printheads typically last for several years, with some lasting up to 10 years or even longer. However, the lifespan can vary greatly depending on usage, maintenance, and environmental factors.
