04: Double Feed Detect
Specify whether or not to detect paper double feeding.
If this is set to "On", the machine stops when it detects paper double feeding, so as
to prevent mixing of unprinted paper.
Double Feed Detect
Note:
• The machine may erroneously detect double feeding when using special paper
(two-ply paper such as release paper). In such a case, set this to "Off".
05: Skew Detection
Specify whether or not to detect paper skew.
If this is set to "On", the machine detects paper skew when feeding paper. If paper
is skewed, set this to "Off", and then adjust the image position to correct the skew.
For details about adjusting the image position, see, p.68 "Shift Image Adjustment".
Skew Detection
Note:
• The machine may erroneously detect paper skew when using dark paper or
paper printed to its edges. In such a case, set this to "Off".
06: Colour Paper Edge Detection Adjustment
Adjust the luminance of the contact image sensor (CIS).
The machine's contact image sensor (CIS) may fail to correctly detect paper edges
when using dark colored paper or paper printed to its edges. In such a case, adjust
the luminance so that the sensor can correctly detect paper edges.
Press [+] or [-] to adjust the luminance.
