Sharp ARM237, AR-M277 Service Manual

Quick Reference Guide: AR-M237/M277

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.
