Troubleshooting Scan and Copy Issues
Line discontinuities
When scanning or copying large originals, you may sometimes
find issues such as shown in the following image, where a straight
line (does not have to be horizontal) appears with discontinuities or
small steps. Note the black arrow indicating the scanning direction
in this example.
To correct:
1. Repeat the scan, making sure the product is correctly
positioned (i.e., flat on the floor and does not move).
Note:
Turning the original 90 or 180 degrees and scanning it again
may also solve the problem.
2. If the problem persists, check that the original to be scanned is
not skewed and that it does not become skewed during the
scan. If so, see
“Troubleshooting Scanner Printing Issues” on
Note:
Also try deactivating the automatic de-skew algorithm as
indicated in
“Troubleshooting Scanner Printing Issues” on page 6-
.
3. If there is no skew but the problem persists, clean and
calibrate the scanner as indicated in
and
“Calibrate the Scanner” on page 5-18“Calibrate
4. Take care not to move the printer during the calibration, and
check that the maintenance sheet is correctly positioned
before starting the calibration. Also check that the
maintenance sheet is not damaged before calibrating the
scanner (an old or damaged maintenance sheet may cause
this problem); if damaged, reprint it as explained in
