1912 Feed Motor Speed Adjustment
Adjusts the feed motor speed for the type of print medium in use (plain paper,
translucent paper, film).
Std: (70 MHz/32)/1635 = 1338 pps
For every change of “1”, speed is adjusted 1/1635 or approximately 0.06%.
Example : If the setting is changed by “+10” then:
(70 MHz/32)/(1635-10) =
(70 MHz/32)/(1625) = 1346 pps
1 Plain [-100 to +100/-10/1%]
2 Translucent [-100 to +100/0/1%]
3 Film [-100 to +100/-10/%1]
1916 Fusing Motor Speed Adj.
SP1916 1 to 013 adjust the basic fusing motor speed and correct the speed for
different widths of paper to prevent skew in the paper feed path. Note :
The actual adjustment that the machine applies is the sum of the width
adjustment (1916 010 to 013) and the paper type adjustment (1916 021 to 045).
10 Width:611mm more [-100 to +100/0/1]
