I've got a customer who's machine is printing double images. I haven't been to the machine yet, but he says it's during the paper advance, that they seem to go bad. He also says that sometimes when he turns the machine on, and it's pulling the paper back and forth, going through it's set up routine, it will pull the paper back too far... then the print job comes, and the printer starts printing on the platen cover for an inch or so before the paper advances far enough to start catching the ink.
The paper advance system on this machine really confuses me. The last time I was there, I tried to do the OMAS calibration, but I didn't have the right paper. I tried it with the paper I did have, but it didn't work... it failed. So I would automatically assume the OMAS, but doesn't it also detect paper via a sensor in the carriage? If this were bad, then it would detect paper when there was none... right? Plus, it would fail the OMAS calibration, if it couldn't see the lines it had printed... right?
The only reason I'm obsessing over it being the carriage instead of the OMAS, is because the machine is heavily used, and everything on the carriage has a nice thick sticky coating of old ink on it.
Hopefully, someone can point me in the right direction on this... Kiran.
