Installing Memory
Caution
Static electricity can damage dual
in-line memory modules (DIMMs).
When handling DIMMs, either wear an
antistatic wrist strap or frequently touch
the surface of the DIMM’s antistatic
package, then touch bare metal on the
printer.
If you have not already done so, print a
configuration page to find out how
much memory is installed in the printer
before adding more memory
(page 134).
1 Turn the printer off. Rotate the printer
for access to its right side. Unplug the
power cord and disconnect any
cables.
2 Grasp the cover (as illustrated) and
pull it firmly toward the rear of the
printer until it stops.
3 Remove the cover from the printer.
4 Loosen the captive screw holding the
DIMM access door with a Phillips #2
screwdriver. Open the door.
