Overview
This wireless color laser all-in-one prints, scans, copies and faxes, with automatic duplex printing and a 250-sheet tray plus a 50-sheet auto document feeder. Print speed reaches up to 19 pages per minute, and a 3.5-inch touchscreen handles shortcuts and cloud printing.
Aimed at a small office rather than a home desk, this model bundles fax and a document feeder that many home all-in-ones skip. It ships with a trial of Brother's Refresh toner subscription, which reorders toner automatically once enrolled, and it also works with Amazon's Dash Replenishment for the same purpose.
- 250-sheet adjustable paper tray plus 50-sheet auto document feeder
- Prints up to 19 pages per minute with automatic two-sided printing
- Connects to Google Drive, Dropbox and OneNote from the touchscreen
- Mobile app for remote printing and toner-level monitoring
Who it's for
A small office or home office running color laser output plus scanning, copying and fax needs is the target here, especially where several people print over wifi. Overkill for someone who only prints the occasional page at home and does not need fax or a document feeder.
Strengths and trade-offs
Drawn from this product's published specifications.
- Auto duplex printing saves paper on two-sided jobs
- 50-sheet document feeder speeds up multi-page scanning and copying
- Dual-band wifi plus Wi-Fi Direct for multiple users
- 3.5-inch touchscreen with cloud service shortcuts
- Laser toner and drum costs add up for light home use
- Fax and feeder features go unused in a pure home setting
- Refresh Subscription and Dash Replenishment require enrollment for ongoing toner value
Performance notes
Print speed tops out around 19 pages per minute with scan speeds up to 29 images per minute in black and 22 in color, figures typical of a workgroup laser rather than a home inkjet. Dual-band wifi (2.4GHz and 5GHz) plus Wi-Fi Direct and USB let several people print without fighting over one network band, and the 250-sheet tray combined with the 50-sheet feeder cuts down on refill trips during a busy day.
