This machine has 64 MB of standard memory and one slot for optional memory expansion. You can expand the memory up to 576 MB by installing small outline dual in-line memory modules (SO-DIMMs). When you add the optional memory, it increases the performance for both copier and printer operations.
In general, the machine uses industry-standard SO-DIMMs with the following specifications:
Type: 144 pin and 64 bit output
CAS latency: 2
Clock frequency: 100 MHz or more
Capacity: 64, 128, 256 or 512 MB
Height: 31.75 mm
Dram Type: SDRAM 2 Bank

Note
• | There might be some SO-DIMMs that will not work with the machine. |
• | For more information, contact Brother Call Center. |
Installing extra memory
1 | Turn off the machine’s power switch. Unplug the telephone line cord. |
2 | Disconnect the interface cable from the machine, and then unplug the power cord from the electrical socket.  Note | Be sure to turn off the machine’s power switch before you install or remove the SO-DIMM. |
|
3 | Remove the SO-DIMM cover and interface access cover. |
4 | Unpack the SO-DIMM and hold it by its edges.   IMPORTANT | To prevent damage to the machine from static electricity, DO NOT touch the memory chips or the board surface. |
|
5 | Hold the SO-DIMM by the edges and align the notches in the SO-DIMM with the protrusions in the slot. Insert the SO-DIMM diagonally (1), then tilt it toward the interface board until it clicks into place (2). |
6 | Put the interface access cover and the SO-DIMM cover back on. |
7 | Plug the machine’s power cord back into the electrical socket first, and then connect the interface cable. |
8 | Plug in the telephone line cord. Turn on the machine’s power switch. |

Note
| To make sure that you have installed the SO-DIMM properly, you can print the user settings page that shows the current memory size. (See How to print a report). |
