Using Service Diagnostics
Most of the diagnostic tests are straightforward and require no additional
explanation, but there are some that require that specific conditions be met to
achieve meaningful results. These instructions cover each of the test groups,
listing special instructions, conditions, or other information necessary to
successfully interpret the results of the diagnostic tests.

printer. These values are read-only and cannot be changed.
Engine ROM Version Lists the version number of the code stored in the engine
ROM and its checksum value.

the printer’s activation. This page count is reset if the HVPS/engine logic
