DRAM Test
This test checks the validity of DRAM, both standard and optional. The test repeatedly writes patterns of data to DRAM
to verify that each bit in memory can be set and read correctly.
To run the DRAM Test:
From the Diagnostics menu, navigate to HARDWARE TESTS > DRAM Test.
DRAM Test Testing… appears on the screen, followed by Resetting the Printer.
After the printer resets, the results of the test appear: DRAM Test (x)MB P:###### F:######.
• (x) represents the size of the installed DRAM.
• P:###### represents the number of times the memory test has passed and finished successfully, with the maximum
pass count being 999,999.
• F:##### represents the number of times the memory test has failed and finished with errors, with the maximum
fail count being 999,999.
After the maximum pass count or fail count is reached, or when all the DRAM has been tested, the test stops and the
final results appear.

Duplex Quick Test
The duplex quick test determines if the Duplex Option Top Margin is set correctly. This test prints a duplexed version
of the Quick Test Page that can be used to adjust the Top Margin for the back of the duplexed page. You can run one
duplexed page (Single) or continue printing duplexed pages (Continuous) until Stop (X) is pressed.
