HP Color LaserJet CM4730 Multifunction Printer series - Manual (Page 345)

E Install memory and print server cards
The MFP has two 200-pin DDR SDRAM slots. One slot is filled; a 128 or 256 MB DDR memory module
can be inserted in the open slot.
The MFP also has three flash memory card slots for MFP firmware, fonts, and other solutions.
● The first flash memory card is reserved for MFP firmware. The slot is marked "Firmware Slot".
● The two additional flash memory card slots are for font cards or third-party solutions, such as
signatures and personalities. The slots are marked "Slot 2" and "Slot 3."
CAUTION Do not insert a flash memory card that is designed for use with a digital camera. The
MFP does not support photo printing directly from a flash memory card. If you install a camera-
type flash memory card, the control panel displays a message asking if you want to reformat the
flash memory card. If you choose to reformat the card, all data on the card will be lost.
You might want to add more memory to the MFP if you print complex graphics or PS documents, or if
you use many downloaded fonts. Additional memory also allows the MFP to print multiple collated copies
at the maximum speed.
NOTE Single in-line memory modules (SIMMs) / dual in-line memory modules (DIMMs) used
on previous HP LaserJet printers are not compatible with the MFP.
Before ordering additional memory, see how much memory is currently installed by printing a
configuration page.
