SERVICE PROGRAM MODE OVERVIEW

SP9-4/ SP9-1-4 (Parallel Loop-Back Test)

This tests the standard IEEE 1284 parallel interface using a loop-back connector.
The loop-back connector (P/#: G0219350) is required for this test.
NOTE: Do not use the loop-back connector with P/#: G0109350. This loop-back
connector causes a timeout error.
1. Turn off the machine and attach the loop-back connector to the Centronics
parallel interface.
2. Turn on the machine.
3. Enter the Printer Controller SP mode, and select "Test Mode".
4. Select "Parallel Loop-Back Test", then press the # key.
5. Check the error message. (! 3.1)

SP9-5/ SP9-1-5 (Self-diagnostic Mode)

The controller tests the following devices. If an error is detected, an error code
appears on the operation panel. (! 3.1)
• Resident SDRAM
• ASIC
• NVRAM
• Flash ROM
• NIB

CAUTION
Do not turn off the machine while this test is running.

SP9-30/ SP9-2-1 (Config data)

This initializes the following settings in the controller NVRAM.
• Controller diagnostics error log
• The network parameter settings in the User Tools except for "5. IP Address", "6.
Ethernet Speed", and "7. Network".

SP9-31/ SP9-2-2 (Controller NVRAM )

This initializes all the data in the controller NVRAM, but does not initialize the NIB
settings.
