I am preparing a used C220 with 158K copies for resale & am going thru adjustments to ensure everything is ok.
Copies off the Glass are properly aligned but thru the doc feeder the image shifts up about 6mm.
The centering screws on the document guide are in the middle.
When I try the Auto Original Stop Position Adjustments (with the A4 alignment chart!) the Sub-scan 1 & 2 sides give me OK results but the Main scan adjustments both indicate 'unable'.
I checked the other available adjustments for the ADF with no better results afterwards.
If I open the side guides up and slide the chart off center to the front a few mm's then I can get an OK response but that doesn't resolve the issue - seems to confirm that some kind of centering value is shifted however I cannot find any centering adjustment other than the doc guide plate & it doesn't move far enough.
Any ideas?
