4.3.1 Basic Adjustment

4.3.1.1 Upward Curl Mode

a. Outline
Paper tends to curl upward in certain conditions,
preventing normal delivery/stacking. (See the
following figure.)
If such is the case,
1) Turn over the stack of paper inside the paper source
(e.g., cassette). If doing so makes the upward curling
worse than before, turn back over the stack. If the
paper still develops upward curl and, thus, fails to
deposit itself normally, try enabling the upward curl
mode item.
b. Enabling the Upward Curl Mode
1) Turn off the host machine.
2) Set the bits of SW104 on the finisher controller
PCB as follows:
ON
1 2 3 4 5 6 7 8
3) Turn on the host machine.

proper stacking.
- When this mode item has been enabled, changes in
conditions (e.g., the use of paper with little curl or
paper with downward curl) can cause improper
stacking. In this regard, it is very important to study
the type of paper that is most often used by the user
before enabling this mode item.

4.3.1.2 Special Curl Mode

a. Outline
If paper with irregular curl is deposited*, its edges can
block the delivery slot of the finisher, pushing forward
the exiting stack when the next sheet arrives. (See the
following figure.)
*LDR size only (mainly, Boise Cascade; 75 g/m2 in
weight).
Paper with
appreciable body.
If this is the case,
1) Turn over the stack of paper inside the source (i.e.,
cassette). If paper starts to curl more than before, turn
back over the stack. If the curling is not corrected as a
result, try enabling the special curl mode item.
b. Enabling Special Curl Mode
1) Turn off the host machine.
2) Set the bits of SW104 on the finisher controller
PCB as follow:
