Hardware Tests
LCD Hardware Test
Selecting this test causes the printer to continually execute the LCD display test. To
cancel the test, press Return or Stop.
Button Test
Use the Button Test to verify the operation of each button on the operator panel. When
you select the Button Test the following screen is displayed.
Press and hold a button and CL (Closed) is displayed. Likewise, while a button is not
pressed, OP (Open) is displayed. If the wrong message is displayed, then the button must
be malfunctioning.
To exit the button test, press Return or Stop. The previous menu screen is displayed
when the button is released.
DRAM Memory Test
Use the DRAM Memory Test to check the validity of DRAM (both standard and optional
DRAM). The test involves writing patterns of data to DRAM to verify that each bit in
memory can be set and read correctly. When you select this test from the operator panel,
the following screen is displayed and the printer begins testing DRAM memory for the first
time.
Terminology
:
• P:###### represents the number of times the memory test has passed (finished
successfully). Initially 000000 is displayed for ######. The maximum pass count is
999,999.
• F:##### represents the number of times the memory test has failed (finished with
errors). Initially 00000 is displayed for #####. The maximum fail count is 99,999.
The power indicator blinks indicating the memory test is in process. The printer
continually runs the same test until cancelled from the operator panel (by pressing
Return or Stop).
Each time the test finishes, the screen is updated with the result. If the test passes, then
the Pass Count is incremented by 1. However, if the test fails, then a failure message is
displayed for approximately 3 seconds and then the Fail Count is incremented by 1.
