CHAPTER 13: AF SCANNING SECTION
[ 13 - 16 ]
Adjustment
1. AF Read Pulse Motor Speed Adjustment (Image elongation & shrinkage control in AF scanning)
Checks and adjustment
(1) Set A3-size paper in the paper-feeding tray, place Test Chart No.11 on the AF unit, make a master and
print.
(2) Lay the print on top of the original to confirm that the image elongation or shrinkage is within plus or minus
1.4% from the top to the 350mm line of the test chart image.
(3) If the image elongation or shrinkage is out of this specification, make an adjustment using Test Mode No.
3074 (AF Scanning Speed Adjustment).
* Prior to the adjustment, finish the image elongation and shrinkage in master-making first.
2. AF Scan Start Position Adjustment
Checks and adjustment
(1) Set A3-size paper on the paper-feeding tray, place Test Chart No.11 on the AF unit, make a master and
print.
(2) Check the prints and confirm that 5mm (plus or minus 2mm) of the top scan skip check graduations is
skipped.
(3) If the scan start position is out of the specified parameter, make an adjustment using Test Mode No. 3073
(AF Scan Start Position Adjustment).
3. AF Horizontal Scan Position Adjustment
Checks and adjustment
(1) Set A3-size paper in the paper-feeding tray. Using the AF unit, place Test Chart No.14 on the AF unit and
make a master.
(2) Check the master created on the print drum. Confirm that none of the ”e” images on the left and right of
the original is not omitted.
(3) If any “e” image is omitted, make an adjustment using Test Mode No.3072 (AF Horizontal Scan Position
Adjustment).
4. AF Read Sensor Sensitivity Adjustment
Checks and adjustment
(1) Switch off the machine power and open the AF unit.
(2) Remove the AF cover and close the AF unit.
(3) Turn the variable resistor VR-1 on top of the AF-PCB to adjust LED1 to the maximum brightness.
Checks after adjustment
- Check that LED1 on top of the AF-PCB goes off when an original (normal white paper) is detected by the
AF read sensor.
