Re: T02-400

Re: T02-400
Blow the dust off the lower limit sensor in the back of the machine. Otherwise one of the small gears inside the elevator motor case has broken, or the two white wires running to the elevator motor assy has broken.Comment

Re: T02-400
thanks jermyth, worked like a charm, but now have new problem i hope you can help me with?
after about 500 run, a big blob of ink is coming out from under the clamp on the drum, i am running at the lowest ink possible, the prints are always very dark,
is the machine running too much ink, or could there be something wrong with the drum? hoping you can help.Comment

Re: T02-400
Two possible problems with the ink blob. 1. Need a new impression roller. It has gotten warpped over time and use and is stressing the drum. 2. Drum has blown the ink blocker under the screen, drum needs to be repaired by a tech.
It is possible that both problems are happening too.Comment
