HP Color LaserJet 4650 Printer series - Manual (Page 122)

Managing memory
This printer supports up to 544 MB of memory: 512 MB DDR plus 32 MB of additional
memory on the formatter board. You can add additional memory by installing dual data-rate
(DDR) memory. To allow for memory expansion, the printer has two DDR slots, which
accept 128 or 256 MB of RAM each. For information about installing memory, see
Working
with memory and print server cards .
Note Memory specification: HP Color LaserJet 4650 series printers use 200-pin small outline dual
inline memory modules (SODIMM) that support 128 or 256 MB of RAM.
The printer features Memory Enhancement Technology (MEt), which automatically
compresses page data to provide the most efficient use of the printer’s RAM.
The printer uses DDR SODIMM. Extended data output (EDO) DIMMs are not supported.
Note If memory problems occur when you are printing complex graphics, you can make more
memory available by removing downloaded fonts, style sheets, and macros from printer
memory. Reducing the complexity of a print job from within an application can help avoid
memory problems.
