AR-5012 SIMULATION, TROUBLE CODES 10 - 13
50 01 Lead edge image position
Used to adjust the copy image position and the lead edge void quantity on the copy paper. The adjustment is made by adjusting the
image scan start position and the print start position (resist roller ON timing) at 100%.
(Operating procedure)
When this simulation is executed, the current setup value is displayed the current setup value is displayed in two digits. (Center value:
50) Press the copy mode select key to select your desired coy mode, and the display will change. Enter the adjustment value with the
10-key and press the PRINT switch, and the setup value will be saved and a copy will be made. Press the clear key to save the setup
value and exit from the simulation mode. When the adjustment is made for the main cassette feed, all the adjustment values at all the
paper feed ports become the same. (Increasing the setup value by 1 corresponds to about 0.1mm shift.)
(Adjustment procedure)
1. Set the print start position (A), the lead edge void quantity (B) and the scan start position (C) to 0, and make a copy at 100%.
2. Measure the image loss quantity (R mm) of the scale.
Set C = 10
×
R (mm) (Example: Set 40.)
When the value C is increased by 10, the image loss is decreased by 1mm.
(Default: 50)
3. Measure the distance (H mm) from the paper lead edge to the image print
start position.
Set A = 10
×
H (mm) (Example: set 50)
When the value A is increased by 1mm, the image lead edge is shifted to
the paper lead edge by 1mm. (Default: 50)
4. Set the lead edge void quantity to B = 50 (2.5mm). (Default: 50)
When the value B is increased by 10, the void is increased by about 1mm.
(When set to 25 or less, the void becomes zero.)
∗
The SPF adjustment is performed by adjusting the SPF image scan start position.
10 Center offset adjustment
Used to adjust the copy image position on the copy paper and the center offset position when scanning a document.
(Operating procedure)
When this simulation is executed, the current setup value is displayed. Enter the adjustment value with the 10-key and press the PRINT
switch, and the entered value will be saved and a copy will be made. When the clear key is pressed, the entered value will be saved
and the simulation will be terminated. (When the setup value is increased by 1, shift is increased by 0.1mm.)
∗
When the setup value is too great, outside of the shading area may be read, and black streaks may be produced on the edges.
When the adjustment value is increased, the image is shifted to the left.
When the adjustment value is decreased, the image is shifted to the right.
