PAPER FEED SECTION (MAIN BODY)
For the Paper Bank Unit – Tray 1/Tandem Tray
To ensure that the paper reaches the paper clamper on the pressure cylinder
properly. Changing the paper clamping timing with SP6-151-1 changes the paper
feed length for the paper registration roller (main body).
CAUTION: Do not change SP6-144 to 6-150 (these change the registration motor
start timing). In addition, do not change SP6-151-3.
1. Turn on the main switch, then access the SP mode.
2. Enter SP6-151-1.
NOTE: From the paper tray (see the previous page), paper clamping timing
depends on the paper type selected at the operation panel. However, the
paper bank unit takes normal paper only, so there is only one SP mode (it
is for normal paper only).
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 SP6-151-1: "145")
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.
For the Paper Bank Unit – Tray 2
To ensure that the paper reaches the paper clamper on the pressure cylinder
properly. Changing the paper clamping timing with SP6-151-2 changes the paper
feed length for the paper registration roller (main body).
CAUTION: Do not change SP6-144 to 6-150 (these change the registration motor
start timing). In addition, do not change SP6-151-3.
1. Turn on the main switch, then access the SP mode.
2. Enter SP6-151-2.
