I do some of the basic troubleshooting for our copiers and I came across this error after removing a paper jam (accordian style) at the exit of the drum unit. I had to remove the drum unit to get all of the paper out. After powering back up everything looks ok. When I make a copy I get the f-28-2 error. When I open the front door there is paper about half way out of the drum unit.
This copier just came in a couple of months ago from another division and we did not renew the contract. . .yet!
Is this an easy fix or something for a Konica tech?
Shorting transfer corona,either shorting or broken wire, if it is shorting replace the entire assembley.it can also be the contact block on the duplex door, either way i would call a qualified tech,hope this helps
