Toshiba MR-3031-B RADF 100-Sheet Reversing Automatic Document Feeder

Duplex Document Feeder for e-STUDIO Multifunction Systems

The Toshiba MR-3031-B RADF is a reversing automatic document feeder that mounts on compatible e-STUDIO multifunction printers. It holds 100 A4 or Letter originals and processes both single-sided and duplex sheets without manual turning. A reversing mechanism flips each original so the host MFP captures the reverse side in the same job.

Feed speed reaches more than 73 sheets per minute at 300 dpi and more than 50 sheets per minute at 600 dpi on single-sided work. Duplex feeding runs at approximately 25 sheets per minute at 600 dpi. The unit accepts paper from 35 to 157 g/m² on single-sided jobs and 50 to 157 g/m² on double-sided jobs.

Supported original sizes cover A3, A4, A4-R, A5-R, B4, B5, B5-R, Folio, Ledger, Legal and Letter. The feeder draws DC 5V and DC 24V from the host machine and consumes 5 W or less. It measures 575 x 531 x 135 mm and weighs about 11 kg. A jam access cover and LED notification lamp speed up clearing and status checks.

Why Choose the MR-3031-B

• An 11 kg frame and 135 mm height keep the feeder stable while leaving the scanner bed accessible.
