Printer memory (HP Color LaserJet 5500 models)
The printer has five dual in-line memory module (DIMM) slots.
Note
For maximum flexibility in DIMM support, the formatter is designed with four 168-pin DIMM
slots and a fifth 100-pin DIMM slot. Due to technical limitations, only four DIMMs can be
loaded at a time, so the fifth DIMM slot (100-pin) is logically the same as the fourth DIMM
slot (168-pin). The system can only have a DIMM installed on the fourth DIMM slot (168-pin)
provided that no DIMM is installed in the fifth DIMM slot (100-pin) and vice versa.
Use these DIMM slots to upgrade the printer with:
● More printer memory - DIMMs are available in 64, 128, and 256 MB
● Flash memory DIMMs - available in 4 MB; unlike standard printer memory, flash DIMMs
can be used to permanently store downloaded items in the printer, even when the printer
is off
● DIMM-based accessory fonts, macros, and patterns
● Other DIMM-based printer languages and printer options
You may want to add more memory to the printer if you often print complex graphics or
PostScript documents, or if you use many downloaded fonts. Additional memory also allows
the printer to print multiple, collated copies at the maximum speed.
Note
Single in-line memory modules (SIMMs) used on previous HP LaserJet printers are not
compatible with the printer.
Before ordering additional memory, print a configuration page to see how much memory is

Installing memory and font DIMMs (for HP Color LaserJet
5500 models)
You can install more memory for the printer, and you can also install a font DIMM to allow
the printer to print characters for languages such as Chinese or the Cyrillic alphabet.
CAUTION
Static electricity can damage DIMMs. When handling DIMMs, either wear an antistatic wrist
strap, or frequently touch the surface of the DIMM antistatic package and then touch bare
metal on the printer.
1. Turn the printer off, and disconnect all power and interface cables. Locate the formatter
board in the rear of the printer.
