3.9.18 PAPER FEED LENGTH ADJUSTMENT
Paper Feed Motor Stop Timing Adjustment
PURPOSE: To ensure that the paper reaches the registration roller properly.
Changing the paper feed motor stop timing with SP6-031-2 changes
the paper feed length for the paper feed roller.
CAUTION: Do not change SP6-014 and 6-015 (these change the paper feed
start timing).
Procedure - Main Body
1. Turn on the main switch, then access the SP mode.
2. Enter SP6-031-2.
3. Increase or decrease the value on the display.
NOTE: 1) Before changing the value, check the current setting, in case you
need to recover the previous setting. (Default for SP6-031-2 – "21")
2) Changing the value by +1 increases the paper feed motor's on-time
and feeds the paper an extra 0.3 mm.
4. Leave the SP mode, then check the paper feed performance. If the problem still
occurs, repeat the above steps.
