Single In-Line Memory Modules (SIMMs)
Additional printer memory allows you to increase data transfer and
processing speed. To install SIMMs,
1. Follow the instructions in “Removing the Controller Board”
(earlier in this chapter), being careful to discharge
electrostatic buildup before you begin.
2. Turn the controller board so that the side where the SIMMs
are located is closest to you and the SIMMs are located on
your right side.
3. If there are enough open connectors for the additional SIMMs
you are installing, skip to step 6. However, if you need to
remove existing SIMMs to make space for new ones, follow
the instructions in steps 4 and 5.
4. If you need to remove a SIMM to make room for
larger-memory SIMMs: Use the clips located on each side of
the connector to gently release the SIMM.
CAUTION: If you are removing SIMMs, remember that printer
operation requires at least 12 MB of total memory, with at least 4
MB of that memory in the slot closest to the center of the board.
