Why the AR-M237/M277 …

The Sharp 23-ppm AR-M237 IMAGER and the 27-ppm
AR-M277 IMAGER are designed with advanced features
that help users maximize productivity. These IMAGERs
come standard with a 100-sheet RADF that feeds up to
43 originals per minute, electronic sorting, auto-duplex
capability, and 1200 dpi output.

These IMAGERs offer standard PC printing that outputs
jobs at up to 1200 x 600 dpi (enhanced) resolution. For
speedy printing, Sharp’s host-based print controller
utilizes JBIG compression, which reduces the job’s file
size, and with a standard USB-2.0 interface, the AR­M237/M277 IMAGER can transfer data up to 40 times
faster than USB-1.1.

With the optional Super G3 Fax Module i, the AR­M237/M277 IMAGERs become powerful workgroup
facsimiles, offering advanced features such as duplex
scanning, job build, F-code communication, ledger-size
reception, and more. Ideal for high-volume faxing, the
AR-M237/M277 IMAGERs can also broadcast up to 200
destination, and can store up to o500 auto numbers, all
of which can be managed through the touch-screen
display.

Powerful Features for Increased
Security

To secure your electronic documents and
restrict access, the AR-M237/M277 IMAGERs
offer several levels of network and data
security.
