4.3.1 Basic Adjustment

4.3.1.1
Upward
Mode
a. Outline
Paper tends to curl upward in certain
conditions, preventing normal delivery/
stacking. (See the following figure.)
F-4-1
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.

3) Turn on the host machine.
- When this mode item is enabled, the
machine changes the speed of its stack
delivery roller to ensure 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
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).
