Parallel Wrap Test
The Parallel Wrap Test checks the operation of each parallel signal,
using a wrap plug. To perform the wrap test, follow these steps:
• Disconnect the parallel interface cable, and install the parallel
wrap plug.
• Select HARDWARE TESTS from the Diagnostics Menu.
• Select Parallel Wrap to initiate the Parallel Wrap Test.
• Select the appropriate Parallel Wrap Test
(Parallel Wrap, Parallel 1 Wrap).
The printer begins testing the parallel hardware and the following
screen displays:
Terminology:
P:###### represents the number of times the memory test finishes
successfully. Initially 000000 displays for ######. The maximum
pass count is 999,999.
F:##### represents the number of times the memory test finishes
with errors. Initially 00000 displays for #####. The maximum fail
count is 99,999.
The power indicator blinks indicating the memory test is in process.
The printer continually runs the same test until cancelled from the
operator panel by pressing Return or Stop. Each time the test
finishes, the screen is updated with the result. If the test is
successful, the Pass Count increments by 1.
