PCL Board Settings
The PCL board uses DIP switches to control the registration of prints. Change these set-
tings only if directed to do so when following TAG #807.
Printhead Circuit Board Settings
The printhead circuit board uses jumpers to match printhead characteristics to controller
characteristics. Do not change these jumper settings; they should remain as set at the fac-
tory.
