Determining memory requirements

The amount of memory you need depends on the types of documents you print. Your print engine can print most text and graphics at 1,200 dpi FastRes without additional memory.

Add memory to your printer if you:

●commonly print complex graphics.

●use many temporarily downloaded fonts.

●print complex documents.

●print two-sided documents.

●use advanced functions.

●print PostScript documents.

Installing memory and fonts

		To install DDR memory DIMMs
		Use this procedure to install additional memory. Before you begin, print a configuration page
		(see To print a configuration page) to find out how much memory is installed in the printer before
		adding more memory. The table lists the maximum amount of memory allowed for each DIMM
		slot.

Note		On the HP LaserJet 9040/9050 base model, to obtain 512 MB of memory, you need to remove
		the 64 MB that came with the printer and replace it with 256 MB.
		On the HP LaserJet 9040n/9050n and the HP LaserJet 9040dn/9050dn, to obtain 512 MB of
		memory, you need to remove the 128 MB that came with the printer and replace it with 256 MB.
