Laser safety
The Center for Devices and Radiological Health (CDRH) of the U.S. Food and Drug Administration
has implemented regulations for laser products  manufactured since August 1, 1976. Compliance is
mandatory for products marketed in the United States. The device is certified as a “Class 1” laser
product under the U.S. Department of Health  and Human Services (DHHS) Radiation Performance
Standard according to the Radiation Control for Health and Safety Act of 1968. Since radiation
emitted inside the device is completely confined  within protective housings and external covers, the
laser beam cannot escape during any phase of normal user operation.
WARNING! Using controls, making adjustments, or performing procedures other than those
specified in this user guide may result in exposure to hazardous radiation.

määritetty standardin EN 60825-1 (1994) mukaisesti.
VAROITUS !
Laitteen käyttäminen muulla kuin käyttöohjeessa mainitulla tavalla saattaa altistaa käyttäjän
turvallisuusluokan 1 ylittävälle näkymättömälle lasersäteilylle.
VARNING !
Om apparaten används på annat sätt än i bruksanvisning specificerats, kan användaren utsättas för
osynlig laserstrålning, som överskrider gränsen för laserklass 1.

							Overview
Memory is upgradeable by replacing the memory DIMM. DIMMs are available in 32, 48, 64, 128, and
512 MB.
For ordering information, see 
Order parts, accessories, and supplies
NOTE Single inline memory modules (SIMMs) used in previous HPLaserJet printers are not
compatible with the printer.
The printer also has one EIO slot for expanding the printer networking capabilities. The EIO slot can
be used to upgrade the printer with an  additional network connection, such as a wireless print server,
network card, or a connectivity card for a serial or AppleTalk connection.
NOTE The HP LaserJet M4345 Series MFP comes with a network device already installed.
The EIO slot may be used to provide networking capabilities in addition to those already built
into the printer.
To find out how much memory is installed in the printer,  or to find out what is installed in the EIO
slots, print a configuration page. See 
Use information pages .
262 Appendix E   Working with memory and print server cards ENWW
 
						

							Adding printer memory
You might want to add more printer memory to the printer if you often print complex graphics, print
PostScript (PS) documents, or use many downloaded fonts. Added memory also gives you more
flexibility in supporting job-storage features, such as quick copying. 
Installing printer memory
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.
The HP LaserJet M4345 Series MFP comes with one DIMM slot. If desired, you can replace a DIMM
installed in the slot with a higher memory DIMM.
If 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. See 
Use information pages .
1. After the configuration page has printed, turn the printer off and disconnect the power cord.
2.Disconnect all interface cables.
3. At the back of the device, remove the side  cover by placing your fingers in the indented area
and sliding the cover off.
4. Open the formatter-cage door by grasping the metal tab and pulling the door open.

							5.Remove the DIMM from the antistatic package.
CAUTION To reduce the possibility of damage caused by static electricity, always wear
an electrostatic discharge (ESD) wrist strap or touch the surface of the antistatic package
before handling DIMMs.
6. Hold the DIMM by the edges, and align the  notches on the DIMM with the DIMM slot. (Check
that the locks on each side of the DIMM slot are open.)
264 Appendix E   Working with memory and print server cards ENWW
 
						

							7.Press the DIMM straight into the slot, and press firmly.  Make sure the locks on each side of the
DIMM snap into place.
NOTE To remove a DIMM, first release the locks.
8.Close the formatter-cage door.
9.Replace the formatter cover.
10.Reconnect the interface cable(s).
11. Reconnect the power cord, and  turn the device on.

							Checking DIMM installation
After installing the DIMM, make sure that the installation was successful.
To verify that the DIMM is installed correctly
1.Turn the printer on. Check that the Ready  light is illuminated after the printer has gone through
the startup sequence. If an error message  appears, the DIMM might have been incorrectly
installed. See 
Use information pages .
2. Print a configuration page (see 
Use information pages ).
3. Check the memory section on the configuration page and compare it to the configuration page
that was printed before the memory installation. If the amount of memory has not increased, the
DIMM might not be installed correctly, or the  DIMM might be defective. Repeat the installation
procedure. If necessary, install a different DIMM.
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.

							Save resources (permanent resources)
Utilities or jobs that you download to the device sometimes include reso\
urces (for example, fonts,
macros, or patterns). Resources that are internally marked as permanent remain in the device
memory until you turn the device power off.
Use the following guidelines if you use the page description language (PDL) ability to mark resources
as permanent. For technical details, see an appropriate PDL reference for PCL or PS.
● Mark resources as permanent only when it is absolutely necessary that they remain in memory
while the device power is turned on.
● Send permanent resources to the device only at the
 beginning of a print job and not while the
device is printing.
NOTE Overusing permanent resources or downloading them while the device is printing
might affect device performance or the ability to print complex pages.
ENWW Save resources (permanent resources) 267
