Brother MFC-L6700DW Business Monochrome Laser All-in-One Printer

The MFC-L6700DW is worth considering for shared office document work: retailer evidence identifies printing, copying, scanning and faxing, automatic duplex operation, Gigabit Ethernet and wireless connectivity. Its listed paper capacity and toner option address repeated document jobs. Buy on these documented features, while treating measured speed, print quality, feeder reliability and current running costs as unresolved.

Buyer questions

Before you buy

Does the 48 ppm rating apply to default duplex jobs?

The manufacturer specifies one-sided printing for the maximum speed rating and says changing the default setting is required. The 48 ppm figure is a rating, not a native-verified independent benchmark here. [2], [4]

Compatibility

Is third-party toner guaranteed to work?

No current guarantee is established. The accepted evidence records a retailer's 2019 compatible-cartridge statement, with current firmware compatibility unresolved. [3]

Setup

Can an office share this printer?

The retailer lists Gigabit Ethernet and wireless connectivity. Exact setup steps and current driver support are not verified. [4]

Care and maintenance

What does the toner yield tell me?

The retailer estimates 12,000 pages for TN880. A yield estimate alone does not establish current running costs or your actual replacement interval. [1]

Why is drum life not one fixed page count?

Brother rates approximately 30,000 pages at one page per job or 50,000 pages at three pages per job for Letter/A4 simplex pages. These are rated conditions, not a measured service interval for your unit. [2]

KnowSpec analysis

Office document workflow

The MFC-L6700DW is worth considering for shared office document work: retailer evidence identifies printing, copying, scanning and faxing, automatic duplex operation, Gigabit Ethernet and wireless connectivity. Its listed paper capacity and toner option address repeated document jobs. Buy on these documented features, while treating measured speed, print quality, feeder reliability and current running costs as unresolved.

Method: inferred

Job structure matters for maintenance planning

The TN880 estimate identifies a supply option, while Brother's drum interval changes with pages per job. An office printing many single-page jobs should retain that distinction when planning maintenance. Retailer ease claims do not measure staff time, and no price observations establish a total ownership budget.

Method: inferred

Verify supplies and software before purchase

The accepted compatible-cartridge claim comes from a retailer's historical statement, so it should not be read as a current firmware guarantee. Network interfaces and an automatic document feeder are documented features, while current driver behavior and feeder durability remain gaps. Confirm the intended computer environment and consumables before making the printer part of a daily workflow.
