DC Controller Installation
Caution
When reinstalling the DC Controller PCA it is
extremely important that all cables be properly
routed. If cables are not routed properly, it is
difficult to reinstall the Formatter Cage and cable
damage may result.
When replacing the DC Controller, be sure to set the leading edge
adjustment as shown in the following procedure.
Note
The Leading Edge Adjustment is set at the
factory and is not required as a maintenance
procedure. The Leading Edge Adjustment should
be done only when the DC Controller is replaced.
The following procedure is performed with the Formatter
Assembly removed.
To set the Leading Edge Registration:
1
Install the new DC Controller in the reverse order of the
removal.
2 Run a test print to check the leading edge adjustment (as
shown in Figure 6-28.
3 Use VR202 (LaserJet 4) or VR201 (LaserJet 4 Plus and 5) (see
Figure 6-29) to adjust the leading edge registration to the
dimension shown in Figure 6-28 (a=2mm).
4
Make several test prints (15 ENGINE TEST as shown in
Figures 3-5 and 3-6) and check the adjustment. Repeat the
above steps until the adjustment is correct.
