Adding 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.
Installing 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 M4345 Series MFP comes with one DIMM slot. If desired, you can replace a DIMM
installed in the slot 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
Use information pages .
1. After the configuration page has printed, turn the printer off and disconnect the power cord.
2. Disconnect all interface cables.
3. At the back of the device, remove the side cover by placing your fingers in the indented area
and sliding the cover off.
4. Open the formatter-cage door by grasping the metal tab and pulling the door open.
