a) Specifications
Type EDO RAM DIMM, 72-Pin
Access time 60ns
Capacity 4MB, 8MB, 16MB
b) Operations
This option memory is used to store print data, and it comes in several sizes:4MB, 8MB,
and 16MB.
The printer uses an advanced Memory Reduction Technology that compresses documents,
when necessary. This reduces the memory requirements for printing complex pages. These
could include duplex documents, documents using a variety of fonts, scanned or dithered
photographs and documents containing large amounts of graphical data. This type of
compression greatly reduces memory errors while printing, however, it can also reduce the
print speed and print quality of some documents. With more memory, the printer can handle
more complex documents without having to use compression.
The table below lists the minimum amount of total memory required for duplex printing to
operate effectively. For example, the printer has 4 MB of standard memory so for the 8 MB
listed in the table below, you need an additional 4 MB of memory.
Minimum Memory Requirements for the Duplex Unit

NOTE
Even with a total of 8 MB, you may need to install additional memory if you frequently
print complicated documents that contain large amounts of data.
