Service Manual
1. Lift operation
When the main unit is turned ON, if the tray is at the lower limit
position (lower limit sensor: LDD ON position), the lift motor is
turned ON to lift the tray.
When the paper presence/empty sensor (LPED) is turned ON
within 800 pulses of the encoder signal from start of lifting up the
tray, the lift motor is turned OFF to stop the tray, and the paper feed
solenoid is turned ON to move down the pickup roller. After that,
the lift motor is turned ON to lift the tray. The tray is stopped when
the upper limit sensor (LUD) is turned ON.
Lifting up operation (When LPED is turned ON within 800 pulses of encoder.)
When the tray is pulled out, it moves down by its own weight.

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.
When the transport clutch (LTRC) is turned ON with the transport
motor (LRFM) ON (rotating), the transport roller rotates. When the
paper feed clutch (LPFC) is turned on under this state, the paper
feed roller and the take-up roller rotate. When the paper feed solenoid (LPFS) is turned ON, the take-up roller is pushed down to
press paper.

3. Paper empty detection
When the tray lifts and stops at the paper feed position and during

ADJUSTMENTS
Service Manual
Each adjustment item in the adjustment item list is indicated with its JOB number. Perform the adjustment procedures in the sequence of Job
numbers from the smallest to the greatest.
However, there is no need to perform all the adjustment items. Perform only the necessary adjustments according to the need.
Unnecessary adjustments can be omitted. Even in this case, however, the sequence from the smallest to the greatest JOB number must be
observed.
If the above precaution should be neglected, the adjustment would not complete normally or a trouble may occur.

the content.
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.
Warning
Trouble/Warning
Trouble
The machine is stopped.
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.)

D. Self diag operation
(1) Self diag operation and related work flow
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.

(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-freeCOPYRIGHT

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
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. No part of this publication may be reproduced,
