My L7555 Officejet pro was working great for the last 10 yrs. Love my printer. Recently printing only pink. Test print shows all color except blue. I aligned and self-cleaned but nothing works. May need a new printhead? Pls advice. Thanks.

I suggest you do a Hard Reset on the printer

 

(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.

 

Then, refer to this document: https://support.hp.com/in-en/product/hp-officejet-pro-l7500-all-in-one-printer-series/2511708/model/... and follow the step by step instruction.
