key.
The relationship between the adjustment modes and the lighting
lamps are as shown in the table below.
To select the adjustment mode with SIM 50-10, use the [ ] [ ]
key.
The relationship between the adjustment modes and the lighting
lamps are as shown in the table below.
(1) Lead edge adjustment
1) Set a scale to the center of the paper lead edge guide as shown
below, and cover it with B4 or 8 1/2" x 14" paper.
2) Execute SIM 50-01
3) Set the print start position (AE lamp ON) (A), the lead edge void
amount (TEXT lamp ON) (B), and the scan start position
(PHOTO lamp ON) (C) to 0, and make a copy of a scale at
100%. (AL-2030/2040CS)
For the AL-2050CS, the following LED’s are lighted:
• AE lamp/COPY mode lamp: (A)
• TEXT lamp/PRINT mode lamp: (B)
• PHOTO lamp/SCAN mode lamp: (C)
4) Measure the image loss amount (R mm) of the scale image.
Set C = 10 X R (mm). (Example: Set the value of C to 30.)
When the value of C is increased by 10, the image loss is
decreased by 1mm. (Default: 50)
5) Measure the distance (H mm) between the paper lead edge
and the image print start position.
Set A = 10 X H (mm). (Example: Set the value of A to 50.)
When the value of A is increased by 10, the image lead edge is
shifted to the paper lead edge by 1mm. (Default: 50)
6) Set the lead edge void amount to B = 50 (2.5mm).
When the value of B is increased by 10, the void amount is
increased by about 1mm. For 25 or less, however, the void
amount becomes zero. (Default: 50)
(2) Image rear edge void amount adjustment
1) Set a scale to the rear edge section of A4 or 11" x 8 1/2" paper
size as shown in the figure below, and cover it with B4 or 8 1/2"
x 14" paper.
2) Execute SIM 50-01 to select the image rear edge void amount
adjustment mode.
The set adjustment value is displayed on the copy quantity dis-
play.
3) Make a copy and measure the void amount of image rear edge.
