Installing memory and font DIMMs
You can install more memory for the printer, and you can also install a font DIMM to allow the
printer to print characters for languages such as Chinese or the Cyrillic alphabet.
CAUTION Static electricity can damage DIMMs. When handling DIMMs, either wear an
antistatic wrist strap, or frequently touch the surface of the DIMM antistatic
package and then touch bare metal on the printer.
To install memory and font DIMMs
1. Turn the printer off.
2. Disconnect all power and interface cables
