Hi everyone!
Thats the problem.. The jam occurs when scanning documents throw ADF, original is stopping after exiting the path. Rollers even don't try to pick the next one. Rollers are OK, dusted photointerrupters with compressed air. Problem is not constant, sometimes it jams at once, sometimes it needs kind of 50 originals to jam. I know about the top ADF cover, sometimes it is to blame, but not this time... Do you have any ideas, maybe some common issues?
.P.S. counters are around 100k.
