OKI C5600 printer is printing Blank pages

Try a new cable.

This is an error for the yellow LED head. Check the connection. If you feel confident enough try moving the LED heads around. If the error moves with the LED head then it needs to be replaced. If the same error occurs the the CU pcb need to be replaced.

i got that error on the first day i got my oki c5950 it was a result of a paper jam in the fuser unit, i removed the jamed paper but the error was still there, i contacted oki support and got a detailed explanation on how to fix this error with a patch file, so if u or anyone out there r still having that problem send me a mail on [email protected] and i will forward u the info.
