4020 ADF Scan Glass Dust Check
This feature checks the ADF exposure glass for dust that can cause black lines in
copies. If dust is detected, a message is displayed, but the process does not
stop.
001 Check On/Off Change (0:OFF/1:ON)
Issues a warning if there is dust on the narrow scanning glass of the ADF when
the original size is detected before a job starts. This function can detect dust on
the white plate above the scanning glass, as well as dust on the glass. Sensitivity
of the level of detection is adjusted with SP4020-002.
[0~1/1]
0: Off. No dust warning.
1: On. Dust warning. This warning does not stop the job.
Note: Before switching this setting on, clean the ADF scanning glass and the
white plate above the scanning glass.
002 Detect Level
Adjusts the sensitivity for dust detection on the ADF scanning glass. This SP is
available only after SP4020-001 is switched on.
[0~8/1]
• If you see black streaks in copies when no warning has been issued, raise the
setting to increase the level of sensitivity.
• If warnings are issued when you see no black streaks in copies, lower the
setting.
• Dust that triggers a warning could move be removed from the glass by the
originals in the feed path. If the dust is removed by passing originals, this is not
detected and the warning remains on.
003 Rejection Level
Sets the level for vertical line correction (the black vertical lines caused by dust
on the ADF exposure glass).
[0~7/1]
0: No vertical line correction.
1-7: Enables and sets the level for vertical line correction. If you select a higher
number, this can decrease the unwanted lines caused by dust. But, it can
also erase thin vertical lines of the original.
4301 APS Sensor Output Display
Displays the APS sensor output signals when an original is placed on the
exposure glass. If a non-standard size is placed on the glass, asterisks (*) are
displayed.
4303* APS A5 Size Detection
Selects whether or not the copier determines that the original is A5/HLT size
when the APS sensor does not detect the size.
[0~1/1]
0: Not detected
1: A5 SEF (5
If "1" is selected, paper sizes that cannot be detected by the APS sensors are
detected as A5 SEF. If "0" is selected, "Cannot detect original size" will be
shown.
