[5] OPERATIONAL DESCRIPTION

Service Manual

1. Lift operation

A. Lifting by insertion of the tray

When insertion of the tray is detected, the tray is locked by the tray
lock solenoid so that the tray cannot be pulled out.

When tray lock is settled by turning ON the tray lock sensor (LTLD),
the lift motor is turned ON to lift the tray.

When the tray is lifted, the tray LED blinks and stops at the paper
feed position (upper limit) by turning ON the upper limit sensor
(LUD).

When the tray stops at the paper feed position (upper limit), the tray
LED turns on.

When the paper empty sensor (LPED) turns ON within 1097 pulses
of the encoder signal from start of the tray lifting, the lift motor is
turned OFF to stop the tray, and the paper feed solenoid (LPFS) is
turned ON to lower the pick roller.

After that, the lift motor is turned ON again to lift the tray and stop it
at the upper limit sensor (LUD) ON position.

When the paper empty sensor (LPED) does not turn ON within
1097 pulses, the paper feed solenoid (LPFS) is turned ON with the
lift motor ON to lower the pick roller. The lift motor is stopped at the
upper limit sensor (LUD) ON position and the paper feed solenoid
is turned OFF.

B. Lowering operation by paper empty detection

or pressing the tray SW

When the paper empty sensor (LPED) turns OFF with the tray at
the paper feed position (upper limit) or when the tray SW (LTLSW)
is pressed, the tray is lowered by 542 pulses of the encoder signal
and stopped at the paper supply position.

When the lower limit sensor (LDD) turns ON before lowering the
tray by 542 pulses of the encoder signal, the lift motor is turned
OFF to stop the tray.

When the tray is moving down, the tray LED blinks. When the tray
is stopped at the paper supply position, the tray LED turns OFF.

When the tray is stopped at the paper supply position, the tray lock
solenoid releases the lock so that the tray can be pulled out.

When the tray is lowered with the paper empty sensor (LPED) OFF,
the tray remains at the paper supply position and the tray lock is
kept released.

When the tray is lowered by pressing the tray SW (LTLSW), if the
tray is not pulled out from the paper supply position for 90sec, the
tray lock solenoid locks the tray. When the tray is locked securely,
the lift motor is turned ON to lift the tray.

When the tray is lifting, the tray LED blinks. When the upper limit
sensor (LUD) is turned ON, the tray stops at the paper feed position
(upper limit).

When the tray stop at the paper feed position (upper limit), the tray
LED turns ON.

C. Lowering operation by paper supply

If the tray is pulled out when it is at the paper supply position, the
tray lock solenoid keep the lock released.

When the tray is pulled out, the tray LED turns OFF.

When the paper front surface sensor (LPUD) is turned ON for 2sec
while the tray is pulled out, the lift motor is turned ON to lower the
tray.

When the paper front surface sensor (LPUD) is turned OFF while
the tray is lowered, the lift motor is turned OFF to stop the tray.

When the lower limit sensor (LDD) is turned ON while the tray is
lowered, the lift motor is turned OFF to stop the tray regardless of
the state of the paper front surface sensor (LPUD).

2. Paper feed operation

When the tray is stationary at the paper feed position (upper limit
sensor: LUD ON position) and there is paper on the tray, paper
feed operation can be performed.

Paper feed operation is performed by the transport motor (LPFM),
the transport clutch (LTRC), the paper feed clutch (LPFC), and the
paper feed solenoid (LPFS) at the following timing.

[10] SELF DIAG MESSAGE AND TROUBLE CODE

Service Manual

1. Self diag

A. General

When a trouble occurs in the machine or when the life of a consum­able part is nearly expired or when the life is expired, the machine
detects and displays it on the display section or notifies to the user
or the serviceman by voice messages. This allows the user and the
serviceman to take the suitable action. In case of a trouble, this fea­ture notifies the occurrence of a trouble and stops the machine to
minimize the damage.

B. Function and purpose

1) Securing safety. (The machine is stopped on detection of a
trouble.)

2) The damage to the machine is minimized. (The machine is
stopped on detection of a trouble.)

3) By displaying the trouble content, the trouble position can be
quickly identified. (This allows to perform an accurate repair,
improving the repair efficiency.)

4) Preliminary warning of running out of consumable parts allows
to arrange for new parts in advance of running out. (This
avoids stopping of the machine due to running out the a con­sumable part.)

C. Self diag message kinds

The self diag messages are classified as shown in the table below.

Class 1 User Warning of troubles which can be recovered by

Class 2 Warning Warning to the user, not a machine trouble

D. Self diag operation

(1) Self diag operation

The machine always monitors its own state.

When the machine recognizes a trouble, it stops the operation and
displays the trouble message.

A warning message is displayed when a consumable part life is
nearly expired or is expired.

When a warning message is displayed, the machine may be or
may not be stopped.

The trouble messages and the warning messages are displayed by
the LCD.

Some trouble messages are automatically cleared when the trou­ble is repaired. Some other troubles must be cleared by a simula­tion.

Some warning messages of consumable parts are automatically
cleared when the trouble is repaired. Some other warning mes­sages must be cleared by a simulation.

LEAD-FREE SOLDER

The PWB’s of this model employs lead-free solder. The “LF” marks indicated on the PWB’s and the Service Manual mean “Lead-Free” solder.

The alphabet following the LF mark shows the kind of lead-free solder.

Example:

(1) NOTE FOR THE USE OF LEAD-FREE SOLDER THREAD

When repairing a lead-free solder PWB, use lead-free solder thread.

Never use conventional lead solder thread, which may cause a breakdown or an accident.

Since the melting point of lead-free solder thread is about 40°C higher than that of conventional lead solder thread, the use of the
exclusive-use soldering iron is recommendable.

(2) NOTE FOR SOLDERING WORK

Since the melting point of lead-free solder is about 220°C, which is about 40°C higher than that of conventional lead solder, and its soldering
capacity is inferior to conventional one, it is apt to keep the soldering iron in contact with the PWB for longer time. This may cause land
separation or may exceed the heat-resistive temperature of components. Use enough care to separate the soldering iron from the PWB when
completion of soldering is confirmed.

Since lead-free solder includes a greater quantity of tin, the iron tip may corrode easily. Turn ON/OFF the soldering iron power frequently.

If different-kind solder remains on the soldering iron tip, it is melted together with lead-free solder. To avoid this, clean the soldering iron
tip after completion of soldering work.

If the soldering iron tip is discolored black during soldering work, clean and file the tip with steel wool or a fine filer.
