just had an interesting fault, customer tries to print/copy & memory goes down & then back up to 99%..nothing comes out & in jobs list alongside job it says "stopprint"....even in tech rep mode you cant print out the management list, went on to infohub & found a bulletin, saying it needs firmware GC-4 if HR non stop is set, checked m/c & it already has firmware, m/c only done 130k so HR shouldn't need replacing, reset HR count anyway, set softswitches 51 & 55 back to factory setting & m/c indicated requires DR & DV, set both to F0 & 0C again, both items @ 130%, thought as they'll need replacing i might as well reset counters, m/c started copying/printing again,but is working ok without a C2557 error, so looks like even though counters reset, may not need to replace DV, but will keep you posted as to what happens. Hope this helps someone out of trouble...took me a while to work it out, when i phoned KM....they suggested i replaced the MFP pcb....but then they always do!
