CHAPTER II THEORY OF OPERATION
1. ELECTRONICS
1.1 General Block Diagram
<MX-2001 & MX-2002>
The MX-2001 Mailbox unit is operated according to signals sent from the printer by serial
communication. The MX-2001 and MX-2002 also communicate with each other by serial
communication. Refer to Fig. 2.1 which shows the general block diagram of the MX-2001
and MX-2002.

1.2.1 CPU
The CPU M50727 is a 4 bit one-chip microcomputer which controls the Mailbox unit and
communicates with the printer using serial communications. According to the commands
from the printer, the CPU drives the feeding motor and the solenoid of each bin and then
feeds the paper to the specified bin. If it detects paper full in the specified bin, the CPU
sends the signal to the printer.
1.2.2 Bin solenoid drive circuit
The bin solenoid drive circuit drives the solenoid of each bin which controls the diverter
flap to send the paper to each bin. The diverter flap is opened when the solenoid is
energized and the flap is closed when the solenoid is de-energized. Each drive circuit for
each of the five bins works independently.
This circuit provides a constant current drive to the solenoid. The solenoid is driven at
600mA for 200msec when it is first energized and then it is held by being driven at
150mA.
1.2.3 Entrance solenoid drive circuit
The entrance solenoid drive circuit drives the solenoid which controls the flap to switch
the paper eject tray from the printer to the Mailbox unit. It is the same as the bin solenoid
drive circuit and connected to the entrance solenoid through the I/F PCB.
II-3
1.2.4 Bin capacity sensor
The bin capacity sensors, which are five infrared LEDs, detect whether the bin is full or
not.
The infrared sensor output generated from the sensor PCB is shut off when the bin is full
of paper. The CPU recognizes that the bin is full when the infrared sensor output is shut
off for 20 seconds.
These sensors also detect paper jams. When paper is ejected into the bin, the sensor is
covered temporarily by the actuator. The CPU recognizes that a paper jam has occurred
when the sensor has not cleared after a specified time has passed.
1.2.5 Infrared LED drive circuit
The infrared LED drive circuit drives the five infrared LEDs on the sensor PCB. This
drive circuit is controlled by the CPU.
1.2.6 Power supply LED drive circuit
The power supply LED drive circuit drives the power supply LED when the regulated DC
power, +24V, is supplied when the adapter is connected and plugged in.

1.3.1 Regulator
The regulator generates and supplies the +5V logic power supply from the +24V supplied
by the adapter.
If the adapter is not connected, the regulator generates the +5V logic power supply from
the +24V supplied by the printer. In this case, the +24V supplied by the printer is not
connected with the +24V supply that should be provided to the Mailbox unit from the
adapter.
II-4
1.3.2 Serial I/F circuit
The serial interface circuit transmits and receives data to and from the printer.
1.3.3 Feeding motor drive circuit
The feeding motor drive circuit drives the motor which feeds the paper in the Mailbox unit
according to the signals from the CPU.
1.3.4 Entrance sensor input
The entrance sensor which is connected with the CPU detects whether the paper is fed
into the Mailbox unit or not.
1.4 Sensor PCB
The five infrared LEDs are mounted on the sensor PCB to detect whether the bin is full or
not. The sensor PCB is controlled according to signals from the CPU.
1.5 Power supply LED PCB
The LED which turns on when the +24V is supplied from the adapter is mounted on the
power supply LED PCB.
1.6 Communication with the Printer
A 3-line clock synchronous serial interface is used for communication between the
Mailbox unit and the printer.

2.2 Paper Feed Sequence
This section describes the sequence when paper is fed from the printer to #1 bin as an
example.
(1) When the paper is sensed at the eject actuator in the fixing unit, the printer
specifies which bin of the Mailbox unit the paper is to be ejected to and sends the
command to start the operation of the Mailbox unit. (Refer to Fig. 2.6.)
When the Mailbox unit receives the command, it drives the feeding motor and
starts the timer to open the entrance flap (flap U).

Entrance Flap (Flap U)

(2) While the paper is being fed towards the entrance flap, the Mailbox unit starts
driving the entrance solenoid (solenoid U) and turns on the entrance flap so that
the paper is fed to the Mailbox unit. (Refer to Fig. 2.7.)
If the entrance sensor has not turned on after a specified time has passed, it
detects that a paper jam has occurred.

(3) The Mailbox unit drives the #1 bin solenoid (solenoid A) and sets the #1 bin flap
(
)
(main flap) so that the paper is fed to #1 bin. (Refer to Fig. 2.8.)
If the eject sensor of #1 bin has not turned on after a specified time has passed, it
detects that a paper jam has occurred.

(4) After the paper end is ejected from the printer to the Mailbox unit, the printer sends
the command to stop the entrance solenoid to the unit. As soon as the Mailbox
unit receives the command, it stops driving the entrance solenoid.
(5) After the paper is correctly ejected into the #1 bin, the printer sends the command
to stop the operation of the Mailbox unit. As soon as the Mailbox unit receives the
command, it stops driving the feeding motor and the #1 bin solenoid.

Note:
The above timing applies to the 20ppm mode. It takes twice as long when the printer
is in the 10ppm (1200 dpi) mode.
The timing delay to eject the paper into the next bin upwards is about 0.3 seconds
later than the bin below because the distance between each bin is 39mm. Also, note
that the distance between the #5 bin and the #6 bin is 55mm and the timing is 0.43
seconds later.

CHAPTER III DISASSEMBLY
1. SAFETY PRECAUTIONS
To avoid creating secondary problems by mishandling, be careful to follow the following
precautions during maintenance work.
(1) Always unplug the power cord from the power outlet of the Mailbox unit before
accessing any parts inside the unit.
(2) Be careful not to lose screws, washers, or other parts removed during servicing.
(3) Be sure to apply grease to the gears and applicable positions specified in this chapter.
(4) When using soldering irons or other heat-generating tools, take care not to accidentally
damage parts such as wires, PCBs and covers.
(5) Before handling any PCBs, touch a metal portion of the equipment to discharge any
static electricity charge on your body, or the electronic parts or components may be
damaged.
(6) When transporting PCBs, be sure to wrap them in the correct protective packaging.
(7) Be sure to replace self-tapping screws correctly, if removed. Unless otherwise
specified, tighten screws to the following torque values.
TAPTITE, CUP B
M3 : 7kgf • cm
M4 : 10kgf • cm
TAPTITE, CUP S
M3 : 8kgf • cm
SCREW
M3 : 8kgf • cm
(8) When connecting or disconnecting cable connectors, hold the connector body, not the
cables. If the connector has a lock, release the connector lock first to release it.
(9) After a repair, check not only the repaired portion but also all connectors. Also check
that other related portions are functioning properly before operational checks.
