However, you can upgrade either of these models to a maximum of 384 MB of RAM
through the installation of additional SIMMs.
Additional memory allows you to download more fonts and increase the printer's
buffer (area where data sent from the computer is stored while waiting to be printed).
▲ Caution
: You may also need additional memory to print on some media sizes at
resolutions above 600x600 dpi. Refer to chapter 3, “Advanced Printing Features,” in
the Operation manual for details.

▲ Caution:
It's very important to protect the printer controller board and SIMM from
electrostatic damage. Before performing this procedure, review the anti-static caution
in “Anti-Static Protection” on page 3-2.
Always handle circuit boards by the edges only.
1 In case you need to restore any memory settings after the SIMM installation,
print an advanced status page.
»Note:
Installing SIMMs automatically resets memory defaults. If your memory
settings are specific to your environment, print an advanced status page before
installing SIMMs, so you can recover the current memory settings.
2 Turn off the printer, and then disconnect the power cord and all interface
cables from the printer.
3 Remove the printer’s controller board.
Loosen two screws, one on each end of the I/O connector panel, and, using the
tab on the connector panel, pull the controller board from the printer.
4 Position the controller board on a flat surface so the controller board lies
flat and the I/O connector panel is facing you.
