Chapter 2 Operation of Diagnostic
DC301 NVM Init.
Description: Initializes an NVM area.
In [NVM Init.], any settings for a billing counter, M/C serial No., market, HFSI,
shutdown history and jam/fail counter are not initialized. Settings for a shutdown
history and jam/fail counter are cleared by selecting the [Exit Diagnostics Complete
Exit] screen when exiting the Diag mode.
In [NVM Init.], only [area:SYS] can be executed. [area:IOT] and [area:ALL] cannot be
executed ("Parameter NG" is shown). Therefore, NVM is initialized by downloading
an output setting value for the MCU NVM initialization through the firmware
upgrade. Two types of output setting values are available as described below:
1. Initialization file
Initializes NVMs, except for the following items specific to the machine.
• Serial No.
• Counter (Billing, HFSI, etc.)
• Shipment adjustment item (Color/Tray Regi., relation, magnification, Loop
amount, etc.)
2. Specified Place (Address) Rewriting File
Rewrites the contents of specified address in NVM, mainly for troubleshooting.

1. Enter the Diag (C/E) mode, and select the [Diag. Menu Adjustment] screen in a lower level using
the " → " key.
