Brother MFC-L3745CDW, MFC-L3750CDW & MFC-L3770CDW Toner Cartridges
The Brother MFC-L3745CDW, Brother MFC-L3750CDW and Brother MFC-L3770CDW use the Brother TN253 and Brother TN257 toner series, together with the DR-253CL drum unit, WT-223CL waste toner box and BU-223CL belt unit. Designed for busy small offices and workgroups, these colour multifunction printers use separate black, cyan, magenta and yellow cartridges, allowing each colour to be replaced individually. High-yield Brother TN257 colour cartridges are well suited to regular reports, presentations and marketing documents, while keeping a spare TN-253BK black cartridge available can help reduce interruptions during everyday document printing. Ink Depot has supplied consumables for these printer models since Sep 2018 and is rated 4.8 by customers on Google.
Page output expectations and testing standards
Page yield ratings for TN-253 and TN-257 cartridges follow the ISO/IEC 19798 standard for continuous color laser printing at 5% page coverage. Choosing high-yield TN-257 colour cartridges reduces supply replacement frequency and optimises cost-per-page for busy office environments.

Drum units, belt units, and waste toner handling
In addition to toner cartridges, the Brother MFC-L3745CDW, MFC-L3750CDW, and MFC-L3770CDW rely on separate long-life components. The DR-253CL drum unit lasts up to 18,000 pages, the BU-223CL transfer belt is rated for 50,000 pages, and the WT-223CL waste toner bottle captures surplus toner. Pro Tip: After replacing a drum unit, reset the drum counter on the printer's touchscreen menu to ensure accurate life cycle tracking.

Frequently Asked Questions
Are TN-253 and TN-257 toner cartridges interchangeable across the MFC-L3745CDW, MFC-L3750CDW, and MFC-L3770CDW?
Yes, all three printer models share the same engine and support standard-yield TN-253 and high-yield TN-257 cartridges across all four toner slots.
Can I mix standard TN-253 black with high-yield TN-257 colour cartridges?
Yes, standard and high-yield cartridges fit in the same slots and function together without any operational issues.
Does installing a new toner cartridge reset the "Replace Drum" message on these models?
No, toner cartridges and drum units are separate components with individual life counters. Replacing a toner cartridge will not clear the DR-253CL drum warning.
