Overview
One dual inline memory module (DIMM) slot is available for upgrading the device with the following
? More memory—DIMMs are available in 64, 128, 256, and 512 MB.
? Other DIMM-based printer languages and printer options.
The device uses 100-pin 133 MHz DDR memory modu les. Extended data output (EDO) DIMMs are not
supported.
For ordering information, see
Order parts, accessories, and supplies on page 314.
NOTE Single inline memory modules (SIMMs) used in previous HP LaserJet printers are not
compatible with the device.
The device also has one EIO slot for expanding the de vice networking capabilities. The EIO slot can be
used to upgrade the device with an additional network connection, such as a wireless print server,
network card, or a connectivity card for a serial or AppleTalk connection.
To find out how much memory is installed in the device, or to find out what is installed in the EIO slots,
print a configuration page. See
Use information pages on page 45.
NOTE If memory problems occur when you are pr inting complex graphics, you can make more
memory available by removing downloaded fonts, style sheets, and macros from device memory.
Reducing the complexity of a print job from within a program can help avoid memory problems.
