HP 5L (C3941A) manual Printing an Engine Test, Engine Test Button

	Printing an Engine Test
	The engine test print can be used to verify that the print engine is functioning
	correctly. The Formatter PCA is completely bypassed during an engine test.
	Consequently, this test is useful for isolating engine printer problems. The engine
	test prints a full page of vertical lines down the entire printable area. This page is
	useful for checking and adjusting registration.
N o t e	Perform the engine test with the printer covers in place, as shown in Figure 3-6.
	Refer to “Engine Test” in Chapter 7 for the engine test procedure.
