View Full Version : CLJ 5550 will not duplex

I have a 5550 that won't duplex, but prints fine otherwise. I have replaced the transfer kit and the paper pickup unit. the paper actual gets out of the fuser and reverses down to the paper pickup unit where it stops with a 13.12 error. I don't see the paper bent like it hits something. It's almost like it doesn't get pulled when it gets to the pickup unit to reverse back up the other side. Some one said it was the fuser, but was wanting a second opinion if any one has seen this before.

I haven't seen this on this particular model, but yes, fuser has been the culprit for same problem on other models ...

if it is not the fuser, i have seen the switches next to the fuser that see the flages for paper exit, and duplex paper possition, get so dirty that they cant see the flages. garybear.

What is the page count on this fuser?
A worn fuser can become a timing issue with the duplexer.
