Printer memory and expansion
Overview
This appendix includes:
●Determining memory requirements
●Installing memory and fonts
●Checking memory installation
●Saving resources (permanent resources)
●Installing EIO cards/mass storage
The printer has two double data rate (DDR) memory DIMM slots for upgrading various features. 
●To add more printer memory, DDR memory DIMMs are available in 16, 32, 64, 128, and 
256 MB, for a maximum of 512 MB.
●To increase flash memory cards, available in 16, 32, and 64 MB. Unlike standard printer 
memory, flash memory cards can be used to permanently store downloaded items in the 
printer, even when the printer is off. The printer supports Type 1 and Type 2 flash memory.
●To add flash memory-based accessory fonts, macros, and patterns, use the appropriate 
DDR DIMM.
●To add other flash memory-based printer languages and printer options, use the appropriate 
DDR DIMM.
Note Single in-line memory modules (SIMMs) used on previous HP LaserJet printers are not 
compatible with this printer.
You might want to add more memory to the printer if you often print complex graphics or PS 
documents, print with the optional duplex printing accessory, use many downloaded fonts, or 
print large paper sizes (such as A3, B4, or 11 x 17). 
The printer has two EIO slots fo r expanding printer capabilities:
●One or more network cards.
●A mass storage device, such as a hard disk.

							182Appendix C Printer memory and expansion ENWW
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.
CAUTIONStatic 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.

To install memory
1If 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. (Press 
22 on the numeric keypad when 
the printer is idle.)
2 Turn the printer off. Disconnect the power cord and any cables.
3 Loosen the two captive thumb screws on the back of the printer.
WA R N I N G ! The formatter has sharp edges.
4 Grasp the screws and pull the formatter board out of the printer. Place it on a flat, non-
conductive surface.
 
						

							184Appendix C Printer memory and expansion ENWW 5
Remove the DIMM from the antistatic package. Hold the DIMM with fingers against the side 
edges and thumbs against the back edge. Align the notches on the DIMM with the DIMM 
slot. (Check that the locks on each side of the DIMM slot are open, or outward.)
See  Installing memory and fonts  for the maximum amount of memory for each DIMM slot.
6 Press the DIMM straight into the slot (press firmly). Make sure the locks on each side of the 
DIMM snap inward into place. (To remove a DIMM, the locks must be released.)
7 Slide the formatter board back into the printer and tighten the two screws.

Plug in the power cord and connect all cables. Turn the printer on.
To install a flash memory card
CAUTION Do not insert a flash memory card that is designed for use with a digital camera into the printer. 
The printer does not support photo printing directly from a flash memory card. If you install a 
camera-type flash memory card, a message asking if you want to reformat the flash memory card 
appears on the control- panel display. If you choose to reform at the card, all data on the card will 
be lost.
1 Turn the printer off and disconnect all power and interface cables.
2 Loosen the two captive thumb screws on the back of the printer.

conductive surface.
4 Remove the compact flash from the antistatic package. Hold the compact flash with fingers 
against the side edges and thumbs against the  back edge. Align the notches on the compact 
flash with the compact flash slot.
5 Press the compact flash straight into the slot.
CAUTION Do not insert the flash memory card at an angle.
NoteThe first flash memory slot marked “Firmware Slot” is reserved for firmware only. Slots 2 and 3 
should be used for all other solutions.

Checking memory installation
Follow this procedure to verify th at memory is installed correctly:
1 Check that  READY appears on the printer control-panel display when the printer is turned on. 
If an error message appears, a DIMM might have been incorrectly installed.
2 Press 
22 on the numeric keypad. The configuration page prints.
3 Check the memory section on the configuration page and compare it to the configuration 
page printed before the DIMM installation. If the amount of memory has not increased, one 
of the following situations might have occurred:
 The memory might not be installed correctly. Repeat the installation procedure.
 The memory might be defective. Try a new DIMM, or try installing the DIMM in a different 
slot.
Note If you installed a printer language (personality), check the Installed Personalities and Options 
section on the configuration page. This area should list the new printer language.
