5. Service Tables
For every change of "1", speed is adjusted 1/1848 or approximately 0.054%.
Std: (19.6608 MHz/8)/1848 = 1329.97 pps
Example: If the setting changed by "+10" then:
(19.6608 MHz/8)/(1848-10) =
(19.6608 MHz/8)/(1838) = 1337.11 pps
1911 BP Strt Adj
Adjusts the time that the operator has to adjust the paper skew manually when feeding paper
manually from the bypass tray..
[1.0 to 8.0/2.0/0.1 sec.]

1912 Fed M SpdAdj
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

1916 Fus M SpdAdj
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).
