CAUTION Correct reinstallation of the formatter is critical to correct operation of the
printer. If you are installing a new formatter, follow instructions in the reinstallation tips. If
you are installing a new formatter and a new dc controller in an HP LaserJet 4250 or 4350
Series printer, see the special section that follows this formatter 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.
