I have a couple of these machines and some work great and some not too great. I have two codes a CE90 and a CE50. Havent been able to figure these out any ideas.

I've never seen those codes not that it couldn't happen... is the machine in a warehouse or in an area not climate controlled?

As for CE50 if occurs in es3511/4511 then the automatic image sensor *poof* kaput...

CE90 your drum side section might be very dirty preventing the thermistor to sense the correct value of the drum.

Thanks
