Paper Clamping Timing Adjustment
For the Paper Feed Table
To ensure that the paper reaches the paper clamper on the pressure cylinder
properly. Changing the paper clamping timing with SP6-116-1 (or 6-116-2)
changes the paper feed length for the paper registration roller (main body).
CAUTION: Do not change SP6-112 to 6-115 (these change the registration motor
start timing). In addition, do not change SP6-116-3, -4, -6 or -7.
1. Turn on the main switch, then access the SP mode.
2. Enter SP6-116-1 (or 6-116-2).
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 SP6-116-2. (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. (The default for SP6-116-1 is
"145", and for SP6-116-2 it is "148".)
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.
