Running the test and diagnostic (T&D) programs
The T&D program can be run in two modes: Single Test Mode or Automatic Test Mode. Single Test Mode is used
to run individual tests, for example, to perform an adjustment or print a print test. Automatic Test Mode, which runs
all the tests sequentially, is used to verify correct printer operation. Automatic mode requires manual intervention
for several of the tests.
1. Power off the printer.
2. Remove all paper from the paper paths.
Tests T&D07 through T&D12 and T&D15 can perform paper path sensor tuning. If sensors are tuned with
paper in the path, paper will not feed correctly.
Note: The following step refers to loop-back connectors needed for T&D03 (parallel interface). If the
connector is not available, the test can be bypassed as described in T&D03—Parallel attachment test.
Attention: Power off the printer before installing or removing the parallel or serial option loop-back connectors.
3. If you are here to run T&D in Automatic Mode or to run T&D03 (Parallel Attachment Test) in Single Mode, a
loop-back connector needs to be installed. Install the parallel loop-back connector (PN 08H7269) on the
attachment bezel.
4. Hold the Stop and Test keys at the same time.
5. Power on the printer.
