Adjusting the feed and separator roller
gap (semi-automatic feeder only)
IMPORTANT: Before adjusting the feed and separator roller gap, be sure the feed and separator rollers are clean. Cleaning the feed and separator rollers will frequently resolve document feeding problems.
The adjustment procedure should only be done when feeding and separating problems continue after the feed and separator rollers have been cleaned. For procedures on cleaning rollers, see Chapter 5, Maintenance.
The gap adjustment knob on the control panel increases or decreases the space between the feed and separator rollers. The gap must be adjusted properly for smooth transportation of documents without document overlap.
When documents of different thicknesses are fed in a group, adjust the gap using the thinnest document in the group.
The feed and separator roller gap may have to be adjusted to compensate for:
∙Very thin documents (onion skin, tracing paper, etc.).
∙Very thick documents (card stock, punch cards, cover stock).
∙Some coated documents (photographic paper,
If the gap is not adjusted properly:
∙More than one document at a time may be drawn into the transport system at the same time; not all of the documents will be scanned.
∙Documents may be drawn into the transport too quickly; documents may overlap or be spaced too closely (causing an error display).
∙Documents may become skewed during transport; jamming may occur.
NOTE: Prior to performing the adjustment procedure, the scanner must be calibrated and enabled.
To adjust the feed and separator roller gap:
1.Turn on the side panel switch.
2.Enter function code F04 and enable Counting Only.
3.Press Enter.
4.Press Run.
IMPORTANT: Do not make a gap adjustment while documents are in the feeder or transport system; doing so will produce an inaccurate adjustment.
5.Turn the gap adjustment knob clockwise three complete turns, or until it stops, to open the gap between the feed and separator rollers.
