(RRC-A)
This set value is used to align the document image lead edge
ad the scan image data lead edge in the document table scan
mode.
After starting scanning, the image lead edge position is deter-
mined by using the scanner home position detection signal
(MHPS) OFF timing as the reference.
RRC-A set value = Time (distance) from the output of the
scanner home position detection signal (MHPS OFF) to the im-
age lead edge position.
If this setting is not made properly, the image lead edge posi-
tion (image loss) varies depending on the copy magnification
ratio.
When the set value is increased, the image position is shifted
in the advancing direction on the paper.
When the set value is changed by 1, the image lead edge posi-
tion is varied.
This set value is used to align the document image lead edge
ad the scan image data lead edge in the document table scan
mode.
After starting scanning, the image lead edge position is deter-
mined by using the scanner home position detection signal
(MHPS) OFF timing as the reference.
RRC-A set value = Time (distance) from the output of the
scanner home position detection signal (MHPS OFF) to the im-
age lead edge position.

tion (image loss) varies depending on the copy magnification
ratio.
When the set value is increased, the image position is shifted
in the advancing direction on the paper.
When the set value is changed by 1, the image lead edge posi-
tion is varied.
(SPF)
This set value is used to align the document image lead edge
position and the scan image data lead edge position in the
SPF scan mode.
After starting scanning, the scan image lead edge position is
determined by using the resist sensor detection signal (REGS
ON) timing as the reference.
RRC-A set value = Time (distance) from the output (resist sen-
sor detection signal (REGS ON) to the image lead edge posi-
tion.
This set value is used to align the document image lead edge
