Functional checks
Engine test
The engine test is used to verify that the print engine is functioning
correctly. The formatter is bypassed during an engine test, so the
engine test is useful for isolating printer problems. The engine test
prints horizontal lines down the entire printable area of a page and is
also useful for checking and adjusting registration.
Printing an engine test
The engine test switch is inside the left cover, below the formatter.
To print an engine test, remove the left side cover. See “Left side
cover” on page 80 and depress the engine test switch. A single test
page will print.
Note The formatter must be connected to the ECU to perform an engine test.
(See callout 1 in figure 65 on page 121.) Otherwise, the printer does
not print.
When you remove the left side cover, you must override the door
interlock (SW 301). (See “Paper path check” on page 155.)
