Post charger HV module assemblies
The post charger HV module assemblies are located on the mid-
upper of the rear of the printer. Shown in figure 139 below are the
assemblies in an HP Color LaserJet 8550 printer. Compare the
developer/imaging drum bias supply to the same part from an
HP Color LaserJet 8500 printer, in figure 140 on page 289, callouts 1
(the smaller portion) and 2 (the larger portion). The smaller portion is
combined with the larger portion in HP Color LaserJet 8550 printer
models, and so is not present in these models.
