The printhead is blocked on the right side by the residual ink tray being extended after powerup. During reset, the tray moves as it should, several times, but after the printhead does two passes to the left & right, and returns to the right, at the end of the reset sequence, the residue tray is again extended under the printhead, blocking it. Printer the reports carriage jam. It acts like the tray is 180 degrees out of sync with the rest of the printer. Or there is a bad position sensor - if there is one. There are absolutely no paper jams, and the residual ink tray is the only thing that is stopping the printhead.... This happened out of the blue after printing an item from notepad. I have done the "hard reset procedure" - Unplug while powered on, to no avail. Everything appears to move and operate normally till the end of the reset, when the tray extends again, when it should be retracted.

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.

 

Try to move the carriage manually and check if it moves.

 

Refer to this document: https://support.hp.com/in-en/product/hp-officejet-pro-6970-all-in-one-printer-series/8289585/model/1... for carriage jam.

Thank you for the reply! I have actually tried this procedure a number of times with no change. Alas.

Hi @mccoutlet

 

Appreciate you trying the steps. This looks like a hardware issue. I'd suggest you Contact HP in your region regarding the service options for your printer.

 

Thanks!
