MX-LCX2  SELF DIAG MESSAGE AND TROUBLE CODE  10 – 1

MX-LCX2

Service Manual

 

When a trouble occurs in the machine or when the life of a consum-
able 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 fea-
ture notifies the occurrence of a trouble and stops the machine to
minimize the damage.

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 con-
sumable part.)

• The self diag messages are classified as shown in the table

below.

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 trou-
ble is repaired. Some other troubles must be cleared by a simula-
tion.
Some warning messages of consumable parts are automatically
cleared when the trouble is repaired. Some other warning mes-
sages must be cleared by a simulation.

Class 1

User

Warning of troubles which can be recovered by the 
user. (Paper jam, consumable part life expiration, 
etc.)

Service
man

Warning of troubles which can be recovered only by 
a serviceman. (Motor trouble, maintenance, etc.)

Other

Cause

Sensor trouble, LCC control PWB trouble, gear 
breakage, lift motor trouble

Check 
and 
Remedy

Use SIM4-2 and 4-3 to check the operation of the 
sensor and the lift motor. Use SIM15 to cancel the 
trouble.

(PCU) PWB trouble, malfunction due to electrical 
noises

Check 
and 
Remedy

Turn OFF/ON the power to cancel the trouble. 
Check the connector and the harness of the 
communication line.
