DRAM test
The purpose of this test is to check the validity of DRAM memory, both standard and optional. The test
writes patterns of data to DRAM to verify that each bit in memory can be set and read correctly.
To run the DRAM Test:
1. Touch
to select DRAM Test from the menu. The message "DRAM Test Testing…" displays. Then
the message "Resetting" Printer appears, and the power indicator light blinks red.
2. Turn the machine off and on. While the DRAM test executes, the power indicator blinks green.The
following type of message appears:
DRAM Test <### P:###### F:####
• xxx represents the installed DRAM size.
• P:###### represents the number of times the memory test has passed and finished
successfully. Initially 000000 displays with the maximum pass count being 999,999.
• F:##### represents the number of times the memory test 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 pass and failures increments. If the test fails, the
message "Failure" displays for approximately three seconds, and the failure count increases by
one.
The test continues until all standard and optional DRAM is tested. Once the maximum pass count or fail
count is reached, the test is stopped, the power indicator is turned on solid, and the final results display.
To stop the test before completion, turn the machine off.
