This has got me really stumped, in July i had to go to this m/c for a misfeed on tray 1, took out the paper feed unit, carried out my repair & refitted it, a couple of days later kept getting a constant 02-02 error, as they had another m/c, i swapped the paper feed units over & the fault remained with the orignal m/c, spoke to KM helpdesk, they said to replace the PF driver pcb, replaced pcb & all went well, went in today as misfeeding on both of their C364s, carried out the same procedure on both m/c's, one works ok, the other has got the 02-02 error again, have had to disable tray 1, as it lifts up but doesn't detect that there is either no paper or it has reached the top, swapped over both paper feed units & the error stays with the original m/c's.....any ideas as to why the pcb is failing when the pf unit is removed & refitted, the m/c's are unplugged completely from the mains when i work on them
