I recently dug my old HP 2605 out of a back room, installed new color toner cartridges and stupidly installed the firmware update. Now my printer is continuously showing Error 79 on the display and reboots. I searched this forum for a fix and saw that the issue I'm having is with the update I installed. I tried removing and reinstalling the white ribbon in the back of the printer but that only allowed me to print one document, then the error returned. I do not have any RAM installed in the back nor have I ever had additional RAM. Is the printer done or is the previous firmware still available?
