Image processor Service Mode
The Service Mode Tests isolate defective FRUs (image processor board, RAM
SIMMs, Extended Feature (font) SIMM, Network Card (Smart Card, or print
engine). The Service Mode tests are set up in several sections, DRAM Test
Group (to check the optional memory SIMM), IP Board Test Group, the Font
SIMM, the Smart Card, and the individual engine diagnostics. The DRAM and
IP Board Test Groups operate in a continuous loop mode.
Tests can be viewed by using switches 2 or 3 (prev and next on the front panel
display, respectively) to scroll to the desired test, and switch 4 (start/stop on the
front panel display) to initiate the test. If no error is detected, tests will repeat
until switch 4 is pressed again. For group tests the entire test suite is repeated. If
an error is detected, the test failure is displayed on the LCD display and the
failed test is continuously repeated.
To start the Service tests, press switch 3 and hold it down during power up or
reset until “
Initializing Service:
” is displayed on the top line of the front
panel. The second line indicates which switches scroll through the menu, or
select the specific test group or individual test displayed.
The test groups are:
■
Kernel -- select the Kernel group from the front panel.
■
I/O -- select the I/O group from the front panel.
■
RAM -- select the RAM group from the front panel.
■
PWA -- select the PWA group from the front panel.
■
IP Board Test -- select the IP Board Group.
■
Engine -- select the Engine group from the front panel.
