What kind of memory can I use?

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 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 SO-DIMM must have the following specifications:

  • Type: 144 pin and 64 bit output
  • CAS Lantency: 2
  • Clock Frequency: 100 MHz or more
  • Capacity: 64, 128, 256 or 512 MB
  • Height: 31.75 mm (1.25 inches)
  • DRAM Type: SDRAM 2 Bank

  • There might be some SO-DIMMs that will not work with the machine.
  • For more information, call Brother Customer Service.

This type of memory SO-DIMM is available from most major memory suppliers.
