Manage memory
The MFP has two double data rate (DDR) DIMM slots to provide more MFP memory. DDR DIMMs are
available in 64, 128, and 256 MB, for a maximum of 512 MB.
The MFP has two compact flash slots to provide the following features:
●
To add flash-based memory accessory fonts, macros, and patterns, use the appropriate DDR
DIMM.
●
To add other flash-based printer languages and MFP options, use the appropriate DDR DIMM.
NOTE: Single in line memory modules (SIMMs) used on previous HP LaserJet products are not
compatible with this MFP.
For ordering information, go to www.hp.com/support/ljm9040mfp or www.hp.com/support/ljm9050mfp.
Determine memory requirements
The amount of memory you need depends on the types of documents you print. Your MFP can print
most text and graphics at 1200 dpi FastRes without additional memory.
You might want to add more memory to the MFP if you often print complex graphics or PS documents,
print two-sided documents (duplex printing), use many downloaded fonts, or print large paper sizes
(such as A3, B4, or 11 x 17).
Install memory
Use this procedure to install additional DDR memory DIMMs. Before you begin, print a configuration
page to find out how much memory is installed in the MFP. The following table lists the maximum amount
of memory allowed for each DIMM slot.
Slot label on the Configuration page Slot label on the Formatter board Description
Slot 1 J1 256 MB
Slot 2 J2 128 MB
Total 384 MB
CAUTION: Static electricity can damage DDR DIMMs. When handling DDR DIMMs, either wear an
antistatic wrist strap or frequently touch the surface of the DIMM antistatic package, and then touch bare
metal on the MFP.
1. If you have not already done so, print a configuration page to find out how much memory is installed
in the MFP.
2. Slide the optional output device away from the print engine.
