Lead edge position and paper lead edge/rear edge void adjustment
Used to adjust the copy image position on copy paper and the lead edge/rear edge void amounts. Performed by
adjusting the scanning start position and print start position (resist roller ON timing) in 100%.
(Operation/Procedure)
1. When this simulation is executed, the current set value is displayed in two digits. (Center value: 50)
2. When the copy mode select key is pressed, the setting mode and the setting display are changed sequentially.
* The selected adjustment mode is indicated by the lamps as follows.
3. Enter the adjustment value with the 10-key and press the START key. Then the set value is stored and copy is
made. (An increase of 1 in the set value corresponds to 0.1mm shift.)
4. Press the clear key to store the set value and exit the simulation.

Shading check
(Outline)
Used to display the detection level of the white plate for shading. (Vref of AD conversion IC is fixed.)
(Operation/Procedure)
When the START key is pressed, the mirror base unit moves to the white plate for shading and Vref+ voltage of
AD conversion IC is set to 4.5V and Vref- voltage to 0.5V, and the copy lamp is lighted.
This state is kept for 10 sec, and the level of one pixel at the center is detected every second to display on the
value display section.
