Flash ROM program writing mode
(Operating procedure)
When this simulation is executed, “d” is displayed on the display and the machine enters the Flash ROM program writing mode.
Use the writing tool to write the program from PC. During writing, the display indicates as shown below. After completion of 
downloading, turn OFF/ON the power to reset.

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.
