Engine Test
The engine test verifies that the print engine is functioning correctly. The
Formatter PCA is completely bypassed during an engine test. This test is
very useful for isolating printer problems. The engine test prints a full page
of horizontal lines across the entire printable area, and is also useful for
checking and adjusting registration. The engine test prints from Tray 3
only, and can be activated with the Formatter PCA removed.
Note
Tray 3 must be installed and loaded with paper to perform an engine test.
Also, ensure that the EP toner cartridge is installed in the printer.
Engine Test Button Location
The engine test button is located on the DC Controller PCA. It is accessible
through a hole at the right rear of the printer.
Printing an Engine Test
To print an engine test, use a non-metallic object to press the engine test
button (see Figure 7-4). A single test page will print.
