I think it´s a toner issue, check toner input mechanism, mylars and motors.

I have recently had same error code on Ineo +552 after alot of eliminating diff parts i changed the toner hopper drive assembly (complete unit) as it was not driving toner from toner reservoir to imaging unit. This was some weeks ago and machine been fine since then . Hope this helps Mark

Wow..Is it still working?

i would swear that either all the sensor blow at the same time on toner hoppers or ...I dunno...I have this issue now and struggling..not really feeling changing the whole assembly, but hey if there is no other way :? What a bummer!


Thanks for your solution!!
