DRAM Memory Test

The DRAM Memory Test is used 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 this test is selected from the operator panel, the
following screen is displayed and the printer begins testing DRAM
memory for the first time.

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.
