(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

(SPF)
This set value is used to align the document image lead edge

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-B)
This set value is used to adjust the relative positions of the im-
age position on the OPC drum and the copy paper.
This adjustment is made by adjusting the time from the output
timing of the image lead edge signal (LD START signal) to
RRC ON.
At the timing of LD START signal output, the print image is
made on the OPC drum at an optional position with the laser
beam.
Actually the RRC ON timing is determined as follows:
RRC ON timing = This set value (RRC-B) - Lead edge void set
value (DEN-A)
When the set value is increased, the RRC ON timing is de-
layed, decreasing the led edge void area.
When the set value is changed by 1, the lead edge void area is
changed by about 0.17mm (about 0.21mm for AR-4XX series;
about 0.24mm for AR-5XX series).
This set value is used to adjust the relative positions of the im-
age position on the OPC drum and the copy paper.
This adjustment is made by adjusting the time from the output
timing of the image lead edge signal (LD START signal) to
RRC ON.
At the timing of LD START signal output, the print image is
made on the OPC drum at an optional position with the laser

When the set value is changed by 1, the lead edge void area is

(IMAGE LOSS)
This set value (timing adjustment value) is used to determine
the lead edge image loss and the image lead edge reference
position by using the scan image lead edge position set with
RRC-A.
Effective print data is determined from the image lead edge po-
sition data scanned with this set value.

Used to set the timing for the RRC ON timing (paper timing)
set with EEC-B.
RRC ON timing = (RRC-B) - Lead edge void set value (DEN-A)
When this adjustment value is changed, the print image posi-
tion for the paper position is changed. As a result, the lead
edge void area is also changed.
When the set value is increased, the RRC ON timing is ad-
vanced and the lead edge void area becomes greater.
When the set value is changed by 1, the lead edge void area is
changed by about 0.1mm.
