CAUTION Correct reinstallation of the dc controller is critical to correct operation of the
printer. If you are installing a new dc controller, follow the instructions in the reinstallation
tips. If you are installing a new formatter and a new dc controller, see the special section
that follows this dc controller section—
Installing a new formatter and a new dc controller
(LJ 4250/4350 only).
Failure to follow these instructions can result in a printer-configuration downgrade. For
example, an HP LaserJet 4350 printer could perform as an HP LaserJet 4250.
