BrianW 0 Posted March 17 Report Share Posted March 17 (edited) We have seen some banding in solid and gradient colors when printing on our 3800G. We have read online that it could be a roller or a barring inside the machine but am unable to find what we need to fix or replace. Have you seen this?

purnomosetiawan 7 Posted March 18 Report Share Posted March 18 first measure it from edge of paper, make sure it always the same place, from that see service manual, from there you can find caused of banding Quote Link to post Share on other sites
oliphaz 0 Posted March 18 Report Share Posted March 18 Are these lines running parallel or perpendicular to paper travel? Quote Link to post Share on other sites

oliphaz 0 Posted March 18 Report Share Posted March 18 Start with the exposure advance rollers and belts and make sure they are free of any debris, for some reason the paper isn't moving smoothly during exposure. I've had far less drastic instances of what you showed remedied by cleaning the underside of the main exposure belt. I haven't dealt with a 38 but I'm sure its similar to other Noritsu printers. The exposure drive belts are yellow/orange; they are very tight with minimal play. I've never removed them, but you should be able to clean just turning them slowly with a bit of patience.
