Paper Clamping Timing Adjustment
PURPOSE: To ensure that the paper reaches the paper clamper on the pressure
cylinder properly. Changing the paper clamping timing with SP6-116-1
changes the paper feed length for the paper registration roller.
CAUTION: Do not change SP6-112 to 6-115 (these change the registration
motor start timing). In addition, do not change SP6-116-2, -4, -6, or -
7.
PROCEDURE:
1. Turn on the main switch, then access the SP mode.
2. Enter SP6-116-1.
NOTE: The paper clamping timing depends on the paper type selected at the
operation panel. SP6-116-1 is the adjustment for normal paper only.
For thick paper, use SP6-116-5. (Note that in thick paper mode, paper
clamping is not done.)
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 SP6-116-1 – "143,"
for SP6-116-5 – "150")
2) Changing the value by +1 decreases the registration motor's on-time
and feeds the paper 0.3 mm less.
4. Leave the SP mode, then check the paper feed performance. If the problem still
occurs, repeat the above steps.
