CACHE Test
This test is used to verify the printer processor cache.
To run the CACHE Test:
1. Touch HARDWARE TESTS from the Diagnostics Menu.
2. Touch CACHE Test. CACHE Test Testing... appears on the display. Then the message Resetting the
Printer appears. While the CACHE test executes, the power LED is green. The printer automatically
performs a POR.
The following type of message appears:
• P:###### represents the number of times the cache has passed and finished successfully. Initially
000000 displays with the maximum pass count being 999,999.
• F:##### represents the number of times the cache has failed and finished with errors. Initially 0000
displays with the maximum fail count being 99,999. Initially only four digits appear, but additional
digits appear as needed.
Each time a test is completed, the number of passes and failures is incremented. If the test fails, the message
Failure appears for approximately three seconds, and the failure count increases by one.
The test continues until all of the printer processor’s cache has been tested. Once the maximum pass count or
fail count is reached, the test is stopped, and the final results display.
To stop this test before completion, turn the printer off.
