1.2.9 Operating Specification
1.2.9.1 How to Open Bins
1. Display is changed to user authentication mode when the Open button on
the Multibin Unit is pressed.
Display: Enter Password = XXXX
NOTE: When the Open button on the Multibin Unit is pressed, the
LED of the bin(s) for which password is disabled goes on. At
this time, this bin(s) can be opened. If there is no bin for which
password is enab led , Enter Password=XXXX is not displayed,
and Open Multibin Unit is displayed.
2. Enter password by pressing 4 switches, and all bins which matched the
password will open. The LED of the bin(s) that can be opened goes o n,
and Open Multibin Unit is displayed on the LCD.
If the entered password is incorrect, Password Error is displayed for two
seconds, and Enter Pasword=XXXX is once again displayed afterwards.
3. The bin(s) will be automatically locked 20 seconds after the Open button
is pressed. The Unit goes Off-Line when the Open button is pressed, and
for the next 20 seconds, no operation on the panel except for entering
password is possible.
1.2.9.2 Period in which the Multibin Unit can be opened
o Can be opened When the printer is in a status of lower priority
than XXX Error yyy.
o Cannot be opened During the printer is in SelecType mode, or
during printing.
NOTE: Bins can be opened when the Multibin Unit is not installed on
the printer (mechanical specification).
1.2.9.3 Display of Each Bin’s LED
o Paper Loaded: -
o Locked: Off
o Unlocked: On
o Full: Flash
The bin which is opened at that time will be locked immediately after it is
closed.
If no password is entered and 20 seconds passed after Enter
Password=XXXX is displayed, LCD display returns to the normal state.

2.2 Introduction
This section contains the removal and assembly procedure for main parts
of the Duplex.
2.2.1 Preparation
Before you begin any disassembly and assembly proce dure;
1. Switch OFF the main power.
2. Disconnect the AC power cord from the wall outlet, then start work.
3. Remove the EP cartridge and store it at a dark and safety place free from
direct sunlight.
4. In performing work for the FUSER ASSY periphery, wait until the FUSER
ASSY and its periphery have become cool enough.
5. Disconnect all interface cables from the rear panel of printer.
6. In performing work, to eliminate static electricity in your body, wear
wristbands, etc. to take grounding properly.
2.2.2 Precautions
CAUTION
n Many kinds of screws are used, and do not confuse where
they are used. Using wrong screws could cause the
tapped holes to be broken, or troubles to occur.
n In performing work with parts that are managed as spare
parts but its procedure is not given, make sure how the
parts have been mounted before starting work.
n Optional parts, as a rule, should be removed, but they
may be left in the printer, on condition that they do not
obstruct your work.
2.2.3 Notations in the Manual
The printer orientation expressed in the procedure is defined as follows.
Figure 2-2. Definition of Printer Orientation
o The screws in the illustration imply that they should be loosened and
removed using a cross-tip screw-driver, unless otherwise specified.
o A black arrow in the illustration implies that the part should be moved
in the arrow direction, and when numbers are assigned to black
arrows, the parts should be moved in the order of given numbers.
