Diagnostics and Print Tests
3–2 3255 4073–002
If both the red Paper Status and the green Slip In LED’s are steadily illuminated,
it is an indication that the NVRAM has failed.
When the last step of the Level 0 diagnostics is complete, the Paper Feed button
is enabled and the printer is ready for normal operation.
If the printer does not complete Level 0 diagnostics, the LED’s flash to indicate
the problem. See “Getting Service” in section 4.
Level 1 Diagnostics
Level 1 diagnostics are selected using the DIP switches or the Paper Feed
button. During Level 1 diagnostics, the printer is not communicating with the
host computer. The diagnostics are described in this order:
• Switch Entry Mode
• Internal Switch Pack Values in NVRAM
• Flash Download Mode
• Data Scope Mode
• Verifying Read of MICR Characters
• Checking MICR Noise Level
• Selecting the Font for the MICR Check Reader
• Diagnostic Print Tests
Information About DIP Switch Settings
To run Level 1 diagnostics, use the DIP switches to change settings. See the
following illustration for the location of the switches on the EFP9800 printer.
Keep these points in mind when using the DIP switches:
To turn a DIP switch on, push it down. To turn a DIP switch off, push it up.
The settings can only be changed when the printer is about to enter Level 1
diagnostics. Switch 1 must be set to On, and switch 2 set to Off.
The default options are set at the factory and are stored in non-volatile memory
or NVRAM (also called EEROM). After the settings have been changed and
stored in NVRAM, the DIP switches must be set back to the normal settings for
the printer to operate. For a list of normal settings, see “Setting Switches” in
section 5.
