My printer Envy Photo 6234 stopped printing at once, the symbol lights left and right of the display were flashing and the display showed error code 0X6201922A and XM_CM-Command. Swithing it off and on did not help. Only the text in the display was showing that the printer was not switched off with the ON/OFF switch. That was happened sometimes due to a mains power fail.
I have understood from an HP Agent Jay_Gay24 in a community message of 06-28-21 at 04:20 Am that a type dependant Factory Reset has to be performed. The link to that message is:
Error Code 0X6201922A - HP Support Community - 8096701
How can I get that "privat" message with the procedure that Jay_Gay24 has sent?
