Scanned Image Size Does Not Match Print Size
If your roll paper printouts need to match the length of your scanned or copied files exactly, you can
adjust the document feed.
1. Press the home button, if necessary.
2. Select > General Settings > Scan Settings > Scan Options > Document Feed Adjustment .
3. Tap the adjustment value area to adjust the value directly, or use the +/- buttons to change the
value.
The adjustment value is calculated using the following formula:
[Length of Original]/[Length of Print Result]×100-100 with the result rounded at the second
decimal.
For example, if the length of the original is 50 cm, and the print result is 50.1 cm, the formula would
look like:
50 / 50.1 × 100 - 100 = -0.1996 rounded to -0.2
