SERVICE PROGRAM MODE 1 March, 2000
3: 6-010 (Master writing speed)
This changes the master feed motor speed.
Inputting a positive value stretches the image on the master. Inputting a negative
value shrinks it.
Normally, do not use this SP mode to adjust the vertical magnification. Use it only if
the vertical magnification is not satisfactory by adjusting Scanning Speed (SP6-
011).
4: 6-011 (Scanning speed)
Inputting a positive value stretches the image on the master. Inputting a negative
value shrinks it.
5: 6-050 (Operation panel LCD contrast)
0: Palest, 7: Darkest
6: 6-070 (Master making density)
0: Pale, 1: Normal, 2: Dark
The default is 1: Normal. Changing this moves the user's image density settings up
or down one notch.
7: 6-082 (MTF filters)
A stronger filter leads to a sharper image, but moiré can become more apparent.
Refer to the following diagram for the relationship between this SP mode and filter
strength (the relationship is not linear). Do not use a value of 1; this is for
designer's tests only.
