Hi there!
This case costs us our nerves: colleague was called for blank pages. He tried ITB, 2.transferroller, pcdu´s, printerhead, nothing helped. Boss goes angry & put it in the workshop. 1. thing we find, the drums are covered complete with toner, but only white pages. After changing the DC-controller & updating fw it looks like this:[ATTACH]37959
We took out the complete HV-blackbox & cleaned all cooper-contacts on the back, rebuild it - quality OK.
Greetings...
