Caution:
It's very important to protect the printer controller board and
any associated circuit boards from electrostatic damage. Before
performing this procedure, review the antistatic caution in “Antistatic
Protection” on page 3-2. In addition, always handle circuit boards by
the edges only.
1 Turn off the printer, and then disconnect the power cord and
all interface cables from the printer.
2 Open the printer’s
front cover.
3 Slide the fuser unit out
slightly.
4 Loosen the two
screws on the
controller board panel
and, using the lip on
the left side of the
panel, pull the panel
off of the printer.
