Description

[9] SELF DIAG MESSAGE AND TROUBLESHOOTING [Error code] Monitors the machine conditions. 1. 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. 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 consumable part.) 3. Self diag message kinds Detects/analyzes the content. Warning Trouble/Warning Trouble The machine is stopped. The content is displayed. Trouble/Warning Warning Trouble Troubleshoot the cause. The self diag messages are classified as shown in the table below. Class 1 User Service man Class 2 Other Warning Trouble Other Warning of troubles which can be recovered by the user. (Paper jam, consumable part life expiration, etc.) Warning of troubles which can be recovered only by a serviceman. (Motor trouble, maintenance, etc.) — Warning to the user, not a machine trouble (Preliminary warning of life expiration of a consumable part, etc.) Warning of a machine trouble. The machine is stopped. — 4. Self diag operation A. 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 consumable part has reached its lifetime. NO YES Replace or supply the consumable part. Repair Cancel the selfdiagnostic message with the diagnostics (test commands). Reset Standby state SHARP TROUBLE & ERROR CODES AR-M550N, AR-M550U, AR-M620N, AR-M620U, AR-M700N, AR-M700U 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.

In case of a same trouble in this machine, selection is made with the simulation to write into the trouble memory or not. If this simulation is set, any trouble is written into the trouble memory unconditionally. Operations except for the trouble mode are enabled (READY). For the modes which cannot be operated, only setting is enabled and a message is given to show the operations are disabled. (NOT READY in this case) (Display) (SIMULATION. 26-35) 0: A same trouble as the previous one is not written. (Default) 1: Any trouble is written into the trouble memory unconditionally. When a trouble occurs, a dialog is shown. In the mode where the operation is enabled, the OK button is added to the message. In the mode where the operation is disabled, the OK button is not shown and the display is kept until the trouble is canceled. B.
