Re: GR3770 image position on master

Something might be up with either the SC7700 or the image procssing PCB. See if happens with scanned images, if it does then its something in the machine (image PCB?) or not then something with the SC7700 or even software related.

Good Luck.

I should have thought to try scanning before, but it doesn't help anyway. I made a master and then without touching anything made another master. The second was "behind" the first by nearly 3/8 of an inch. So it appears that it is not software or SC7700 related. Any other ideas? Thanks.

Check the write motor, the pulleys and the belt that drives the write roller. Also disconnect and reseat ALL the connectors on the Image Processing PCB & the TPH Power PCB.

On the end of the write roller is a belt driven pulley. Remove the belt and tighten the allen screw holding it to the shaft.
