Compact colour all-in-one for small offices

The Brother MFC-L3720CDW combines print, scan, copy and fax in a wireless digital laser device. It suits small teams that need colour output and document handling without a large footprint. The 800 MHz processor drives the core functions for everyday office tasks. Buyers who need high-volume paper trays or advanced finishing options will find the capacity limited.

Print and scan throughput with toner capacity

Colour and mono print speed reaches 19 ppm at 2400 x 600 dpi resolution. Simplex scan speeds are 29 ipm for black and 22 ipm for colour at the same optical resolution. Fax transmission runs at 33.6 kb/s with 512 MB memory for inbound pages. The four-toner cartridge set handles colour jobs, though heavy daily print loads will require frequent replacement.

Media flexibility through manual feed and USB

A manual feed slot accepts sizes from 3 x 4.57 inches up to 8.5 x 14 inches for envelopes, labels and legal pages. Standard connectivity includes USB 2.0 for direct computer links alongside wireless operation. The compact frame fits on a desk but offers no automatic document feeder for multi-page scanning. Users who rely on unattended batch scanning or large-capacity trays will need a different model.
