4020 Dust Check Set for Dust Check on ADF Exposure Glass
These SP codes adjust the dust check operation at the ADF scanning glass and the
white scanning belt.
Note: Dust that triggers a warning could 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.
001 Dust Detect:On/Off Switches the dust warning ON and OFF. When this SP is ON,
a warning is issued if the check detects dust on the ADF scan
glass or the white plate above the scanning glass. Always
clean the ADF scanning glass and white plate before turning
this SP ON.
[0~1/1] 0:Off, 1:On
002 Dust Detect:Lvl Adjusts the sensitivity of the check. 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.
