3. Diagnostic Aids
This chapter explains the tests and procedures you can run to
identify printer failures and verify that repairs have corrected the
problem.
Memory Test
The following tests run sequentially when performing this test:
Standard Memory Test
Optional Memory Test
The memory test runs automatically during POST if a different size
optional memory SIMM is installed since the last printer power on.
Perform the following steps to run the Memory Test:
1. Turn the printer off.
2. Open the top cover.
3. Press and hold the operator panel button as you turn on the
printer. Release the button once the Error LED comes on solid.
4. Close the top cover.
5. If all the diagnostic tests run correctly, the Data LED blinks. If a
test fails, the Error LED pattern for the service error code dis-
plays on the operator panel. Go to the “Service Error Codes” on
page 2-2 and take the indicated action for that error.
Diagnostic Test
Once the memory test is complete, the diagnostic test pages can be
printed by briefly pressing the operator panel button. Two pages are
printed. The first page is a listing of various printer settings and code
level. The second page is used to inspect registration. If the printer
requires a registration adjustment, you must contact your next level
of support to obtain the software utility that enables you to adjust
registration.
