A Working with memory
ENWW221
 

Printer memory
You might want to add more memory to the printer if you often print complex graphics or PS documents,
or use many downloaded fonts. Additional memory also allows the printer to print multiple, collated
copies at the maximum speed.
To accommodate memory expansion, the available 200-pin small outline dual inline memory module
(SODIMM) can be upgraded to a maximum of 512 MB of memory. DDR SDRAM memory is available
in 128, 256, and 512 MB modules.
NOTEMemory specification: HP Color LaserJet...

Installing memory
You can install more memory for the printer.
CAUTIONStatic 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.
Installing DDR memory DIMMs
1. Turn the printer off.
2.Disconnect all power and interface cables.
