Printer memory You might want to add more printer memory to the printer if you often print complex graphics, print PostScript (PS) documents, or use many downloaded fonts. Added memory also gives you more flexibility in supporting job-storage features, such as quick copying. CAUTION To install printer memory Static electricity can damage DIMMs. When handling DIMMs, either wear an antistatic wrist strap or frequently touch the surface of the DIMM antistatic package, then touch bare metal on the printer. The HP LaserJet 2400 series printers come with one DIMM installed in slot 1. A second DIMM can be installed in slot 2. If desired, you can replace the DIMM installed in slot 1 with a higher memory DIMM. If you have not already done so, print a configuration page to find out how much memory is installed in the printer before adding more memory. See Configuration page. 1. After the configuration page has printed, turn the printer off and disconnect the power cord. 2. Disconnect all interface cables. 3. Remove the right side panel by sliding it towards the rear of the printer until the side slides free from the printer. ENWW Printer memory 191

To install printer memory

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, then touch bare metal

on the printer.

The HP LaserJet 2400 series printers come with one DIMM installed in slot 1. A second

DIMM can be installed in slot 2. If desired, you can replace the DIMM installed in slot 1 with

a higher memory DIMM.

If you have not already done so, print a configuration page to find out how much memory is

installed in the printer before adding more memory. See

Configuration

After the configuration page has printed, turn the printer off and disconnect the power

cord.

Disconnect all interface cables.
