Enhanced Memory Management
The printer provides its own data compression technology in the printer
hardware and the supplied printer driver software, which can
automatically compress graphic data and font data efficiently into the
printer’s memory. You can avoid memory errors and print most full
page 600 dpi graphic and text data, including larger fonts, with the
printer’s standard memory.

Environment-Friendly
Economy Printing Mode
This feature will cut your printing cost by saving toner. It is useful to
obtain draft copies for proof-reading. You can select from two economy
modes—25% toner saving and 50% toner saving—through the
Windows printer driver supplied with your printer.
Sleep Mode (Power Save Mode)
When the printer is not used for a certain amount of time, sleep mode
automatically reduces power consumption. The printer consumes less
than 7 W when in sleep mode.
Low Running Cost
Since the toner cartridge is separate from the drum unit, you need to
replace only the toner cartridge after approximately 2,200 pages, which
is cost effective and ecologically friendly. (In USA, Canada and some
other areas the printer is supplied with a starter toner cartridge which
must be replaced after 1,000 pages.)
The actual number of pages printed with each toner cartridge may vary
depending on your average type of print job.
