Engine Test
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. This testis therefore useful for isolating
printer problems. The engine test prints a fhll page of vertical lines
down the entire printable area, and is thus also useful for checking
and adjusting re&istration.
Note
An Engine Test can be performed on the
LaserJet 4L and 4ML with the printer covers in
place, as shown in Figure 3-8. The LaserJet 4P
and 4MP require removal of the covers and the
Formatter PCA. Refer to “Engine Test” in
Chapter 7 for the engine test procedure.
