[10] SELF DIAG MESSAGE AND TROUBLESHOOTING

1. Outline

When a trouble occurs in the machine or when the life of a con-

sumable 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.

2. 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 con-

sumable part.)

3. Self diag message kinds

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

4. Self diag operation

A. Self diag operation and related work flow

The machine always nonitors 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.)

Serviceman Warning of troubles which can be

recovered only by a serviceman.

(Motor trouble, maintenance, etc.)

Other —

Class 2 Warning Warning to the user, not a machine

trouble (Preliminary warning of life

expiration of a consumable part, etc.)

Trouble Warning of a machine trouble. 'The

machine is stopped.

Other —

The contents are detected

and analyzed.

Trouble/Warning
