[5] OPERATIONAL DESCRIPTION

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.) Lifting up operation (When LPED is not turned ON within 800 pulses of encoder.)

If the paper presence/empty sensor (LPED) is not turned on within
800 pulses, the paper feed solenoid is turned ON with the lift motor
ON to move down the pickup roller. The lift motor is stopped at the
upper limit sensor (LUD) ON position, and the paper feed solenoid
is turned OFF.

When the machine power is turned on, if the tray is on the paper
feed position, lifting is not performed.

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
paper feed operation, paper presence/empty is detected by the
paper presence/empty sensor (LPED).

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.

ADJ 1 Print off-center adjustment

1) Execute SIM.50-10 by the key operation of the machine. Then,

the displays shown on the right side appear.

2) The print off-center adjustment value can be set for each tray.

3) Press the [↓] key on the touch panel to select “G:50:LCC”.

4) Then, enter your desired adjustment value with the [10] key.

(Default: 50 Adjustment range: from 1 to 99)

* If the adjustment value is decreased by 1, the main scanning

print position is shifted to the front side by 0.1mm.

* If the adjustment value is increased by 1, the main scanning

print position is shifted to the rear side by 0.1mm.

5) When the [EXECUTE] button is pressed, the [EXECUTE] but-

ton is highlighted, currently set value is saved into the
EEPROM and the RAM, and printing for adjustment pattern
image is started. After printing is finished, the [EXECUTE] but­ton returns to the normal display status.

6) Check the adjustment pattern image position.

Measure the dimensions of the void area in the adjustment
pattern front and rear frame directions, and ensure that they
satisfy the conditions shown below.

1) Execute SIM.50-5 by the key operation of the machine. Then,

the displays shown on the right side appear.

2) Press the [↓] key on the touch panel to select “E:PAPER”.

3) Then, enter the adjustment value 6 with the [10] key, and press

the [OK] button.

(Adjustment value 6: LCC)

4) When the [EXECUTE] button is pressed, the [EXECUTE] but-

ton is highlighted, and printing for adjustment pattern image is
started with the currently set value. After printing is finished,
the [EXECUTE] button returns to the normal display status.

5) Check the adjustment pattern image position.

Measure the dimensions of the void area in the adjustment
pattern right and left frame directions, and ensure that they sat­isfy the conditions shown below.

:

If condition of A=4.0±2.0mm, B=4.0±2.0mm is satisfied, no
adjustment is necessary.

If it does not satisfy the condition above, execute the proce­dures shown below.

6) Change the adjustment values of the adjustment items

A(DEN-C) and B(DEN-B).

* As the adjustment value of the item A(DEN-C) is decreased

by 1, the print start position is moved to the lead edge side of
paper against the paper feed direction by 0.1mm.

* As the adjustment value of the item B(DEN-B) is decreased

by 1, the print range is increased to the trailing edge side of
paper against the paper feed direction by 0.1mm.

7) Repeat the steps from 4) to 6) until the condition shown in the

step 5) is satisfied.

8) After the adjustment is finished, escape from the simulation

mode with the reset key.

[10] SELF DIAG MESSAGE AND

TROUBLE CODE

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.

Service Manual

Class 1 User Warning of troubles which can be recovered by the

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

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-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.
