I have a 3600n that when turned on gives a 54.15 error and displays "power off then on to clear error". I do this but get the error again and cannot clear it. What does this error indicate? The printer is out of warranty.
the manual does'nt mention much about this error.and this error varies from printer to printerwhere it sometimes can be a motor error.but on this kind of machine(verticle inline structure),i believe it mostly refers to a color plane registration/density sensor error.where a 54.15 error would more specifically refer to the yellow toner sensor.you could try to do a full calibration from the printer or clean the density sensor.or even the cartridge slot contacts.it's possible that if you disable the cartridge check from the diagnostics menu,it may temporarily clear this error ;(just to test it and see if it's related).
