Hi. There is error j21-01 and j21-51 after changing the drum. The page stops in the middle of the transfer belt. First it's j21-01 and I have to take out the page. Then there's the j21-51 error. I have to turn off the machine to eliminate the error. I turn it on and the same again. Please help.

are you a tech?

Yes, with little experience.

Make sure the grounding tabs are touching the PCC corona. You can also try taking the PCC corona out of the machine and see if you get the same result. Check the springs on the drum separator claws.

Thanks, I'll check it out next week.

Problem solved. The reason was the A0G5H16000 board. Thorough cleaning helped. Thanks for help.
