BH-C-280, DF-626, scan speed?

BH-C-280, DF-626, scan speed.

If I ever would have known I have forgotten how.

DF-626 has often but not always problem with double feeding and/or jamming during take up. Especially with scanning, little less with copying. Since the ADF is rather new with only 20K on the clock and sensors and rollers are clean. I'm not sure where to start, my first idea was to reduce the scan speed, at least for scanning, on a regular base. But how to do it, or perhaps any better ideas please?

Thanks in advance

Set DPI settings 200x200 is fast scanning. adjust up to slow it down.
