Getting Started
The printers have four sockets for memory DIMM boards. You can expand the
printer’s memory up to 1 GB by installing two 512-MB DIMMs. To achieve the 1
GB memory in most models, you will need to replace the DIMM(s) provided with
512 MB DIMMs. The printer will not acknowledge more than 1 GB of memory.
Caution!
Circuit boards can be damaged by static electricity and rough handling. Keep
board in packaging until you’re ready to install it. DIMMs are sensitive to static
electricity. To avoid damage, ground yourself before handling DIMMs.
