3. 4. 2 How to Enter the Service Mode
Check
1. Inform customers that "The machine cannot be used as servicing will be started." (To
suspend a copy job and a local print job.)
2. Connect the Portable Service Work Station (shall be called as PSW below) to the machine.
(Fig. 1)
(Fig. 1) j0mf2402
Take note of the following when supplying power for the PSW from the Service
Outlet on the M/C:
• DO NOT supply power from the PSW AC outlet during Warm Up mode or the
following modes. Wait until "Ready to Copy" is displayed.
Reason: The machine uses 1.5KVA at maximum during Warm Up.
Applicable modes
- Warm-Up mode when the power is turned On
- Recovery mode after Standby mode
- Recovery mode after Sleep mode
- Recovery mode after Diag mode
• Do not connect other equipment except the PSW to this outlet. Connecting with
other equipment except PSW may cause fire/electric shock.
• As this outlet is to be used by the Service Engineer only, reinstall the Cover as
soon as the servicing has completed so that the customer is unable to use this
outlet.
• To enter the Service mode, you must connect the PSW to the PSW connection outlet
(RS232C) on the Main Unit using the RS232C straight cable. (As the machine
cannot identify the type of equipment, it cannot set up the electronic manual,
component names, etc.)
• When the screen indicating the [Retry] button is displayed, press the button after
making sure that the machine operation has stopped.
