Image processor diagnostics
Full verification test
Verification Tests are a subset of the tests available in the Image Processor
Service Mode discussed below. The Verification Tests are those individual
Service Mode tests not requiring operator intervention or any consumables.
These tests take up to 5 minutes (depending on optional memory installed) to
complete. To enter this mode:
■
Press and hold down front panel switch 2 during power up or reset
until
VERIFYING
is displayed on the front panel.
■
At the beginning of each test a message is sent out the RS232 port and
to the front panel to indicate which test is about to start. The RS232
port is configured for 9600 baud, 8 bits of data, no parity and 2 stop
bits.
When the Verification Tests have completed, the test suite restarts and execute
repeatedly until power is turned off. If an error is detected, the test with the
error will execute in a loop until power cycled or reset. Also with each error an
error message will be sent out the RS232 port and displayed on the front panel.
