✒ Note
The printer has only one slot for a SIMM upgrade.If you want to increase
your printer memory again after you have installed a SIMM module into
the slot, you will need to remove the previously installed SIMM first. For
example if you have previously increased your memory from the standard
4 MB to 8 MB by adding a 4 MB SIMM and you wish to increase your
total memory to 12 MB, you need to remove the installed 4 MB SIMM
and install the new 8 MB SIMM into the printer.
Installing the SIMM
When you install the SIMM, follow these steps:
1. Turn off the power switch and unplug the power cord from the AC
outlet. Then, disconnect the interface cable from the printer.

removing the SIMM and the main controller board.
