[5]OPERATIONAL DESCRIPTIONS
1.Lift Operation
When the power to the main unit is turned ON with the tray at a
midway position (that is, a position where both the upper limit sensor [LUD] and lower limit sensor [LDD] are OFF) or with the tray at
the lower limit position (where the lower limit sensor LDD is ON),
the main unit issues a lift-up request and, in response, the lift motor
is turned ON to lift the tray.
If the Paper-on-tray sensor (LPED) turns ON within 800 encoder
pulses of the start of tray lift, the lift motor is temporarily turned OFF
to stop the tray, and then the paper feed solenoid is turned ON to
lower the pick roller. Subsequently, the lift motor is turned ON, and
the tray is lifted to and stopped at a position where the upper limit
sensor (LUD) is turned ON.
If the Paper-on-tray sensor (LPED) does NOT turn ON within 800
pulses of the start of tray lift, the paper feed solenoid is turned ON
with the lift motor remaining ON, and the pick roller is lowered. The
lift motor stops when the tray reaches a position where the upper
limit sensor (LUD) is turned ON, and subsequently the paper feed
solenoid is turned OFF.
Lift operation is not performed if the power to the main unit is turned
ON with the tray at a position where it can feed paper.
When the tray is drawn out, it lowers by its own weight.
Service Manual
2.Paper Feed Operation
Paper feed operation can be performed if the tray is stationary at a
position where it can feed paper (with the upper limit sensor [LUD]
being ON) and there is paper in the tray.
When paper feed takes place, the transport motor (LPFM), the
transport clutch (LTRC), the paper feed clutch (LPFC), and the
paper feed solenoid (LPFS) operate with the following timings:

*1:
Operation stops only if the main unit synchronization signal is output.
When operation is stopped, the ON/OFF timing for each load is delayed by the stoppage time because each timer is suspended during the
stoppage.
To ensure efficient job processing, operation is not stopped under normal conditions.
When the transport clutch (LTRC) turns ON with the transport
motor (LPFM) is ON (rotating), the transport roller starts rotating.
When the paper feed clutch (LPFC) turns ON in this state, the
paper feed and take-up rollers start rotating.
When the paper feed solenoid (LPFS) turns ON, the take-up roller
is pushed down to press paper.

3.Paper-on-tray Detection
The Paper-on-tray sensor (LPED) checks whether there is paper in
the tray when the tray is lifted and stopped at a position where it
can feed paper, as well as during paper feed operation.
Paper feed operation is stopped if the sensor detects no paper in
the tray during paper feed operation.

[8]ADJUSTMENT
Each adjustment item in the adjustment item list is indicated with its
JOB number. The adjustment procedures should be performed in
the ascending order of Job numbers.
However, you do not have to always perform all the adjustment
items. Perform only the necessary adjustments according to the
actual conditions.
Skip any unnecessary adjustment items, and perform the next necessary item. Even with some items skipped, the adjustment procedures should be performed in the ascending order of Job numbers.
Failure to perform the adjustment items in the correct order may
result in adjustment errors or some other problems.

C. How Self-diagnosis Works
(1) Self-diagnosis and Troubleshooting Workflow
The self-diagnosis program built in the machine is always the monitoring machine function.
When the self-diagnosis program detects a trouble condition, it
stops the machine and displays the appropriate trouble message.
Typically, warning messages are displayed when there is a consumable part whose life is nearly or already expired.
Some warning messages are displayed without machine stoppage,
while other warning messages are displayed at the same time as
machine stoppage.
Trouble and warning messages are displayed on the LCD with one
or more specific indicator lamps lit or flashing.
Some trouble messages are automatically cleared upon recovery
from the trouble, while other trouble messages must be cleared
using the corresponding SIM.
Also, some of warning messages associated with consumable
parts are automatically cleared upon replacement or refill of the
consumable part, while other messages must be cleared using the
corresponding SIM.
2.Self-diagnosis
When a trouble condition occurs in the machine or when there is a
consumable part whose life is nearly or already expired, the
machine's self-diagnosis program detects and analyzes the condition and issues the appropriate notification on the display panel so
that the user and the serviceperson can take suitable action. In the
case of a trouble condition (rather than the expiration of a part's
life), the self-diagnosis program not only issues the appropriate
notification but also stops the machine to minimize damage.
A. Functions and Objectives
1) Ensures safety by stopping the machine as soon as a trouble
condition is detected.
2) Minimizes damage to the machine by stopping the machine as
soon as a trouble condition is detected.
3) Displays the description of the trouble condition so that the
user or serviceperson can quickly and accurately identify the
source of the trouble. This helps the serviceperson to perform
repair work most effectively and efficiently.
4) Issues an alarm when there is a consumable part whose life is
nearly expired so that the user can order the consumable part
before its life is actually expired. This helps prevent machine
outage due to the absence of a consumable part.
B. Types of Self-diagnosis Messages
Self-diagnosis messages can be classified into the following types:
Classification 1UserThis type includes user-recoverable
trouble or warning conditions (such as
paper jam or consumable part life
expiration).
ServiceThis type includes serviceperson-
recoverable trouble or warning
conditions (such as motor trouble or
maintenance).
Miscellaneous—
Classification 2WarningThis type includes those messages that
are primarily intended to warn the user
and not directly related with machine
trouble (such as a warning message
issued when there is a consumable
part whose life is nearly expired).
TroubleThis type includes those messages that
are directly related with machine
trouble and issued at the same time as
machine stoppage.

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.

table at the right.)

(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.
