<Installing accessories>

Your printer is a full-featured laser printer that has been optimized to 
meet the majority of your printing needs. Recognizing that each user 
may have different requirements, however, Samsung makes several 
accessories available to enhance the printer’s capabilities.

This chapter includes:
•

Never remove the control board cover while the printer is plugged in.

To avoid the possibility of an electrical shock, always disconnect the 
power cord when installing or removing ANY internal or external 
accessories.

The control board and internal accessories (network interface card, 
DIMM, and hard disk) are sensitive to static electricity. Before installing 
or removing internal accessories, discharge static electricity from your 
body by touching something metal, such as the metal back plate on any 
device plugged into a grounded power source. If you walk round before 
finishing installation, discharge any static electricity once again.

Your printer has a dual in-line memory module (DIMM) slot. Use this 
DIMM slot to install additional memory.

Your printer has 128 MB of memory which can be expanded to 512 MB. 
For information about ordering optional DIMMs, see page 7.1.

Turn the printer power off and unplug the power cord and printer 
cable from the printer.

Remove the duplex-slot cover or the duplex unit from the back of 
the printer.
