MFC-L3745CDW Replacement – Upgrade to Brother MFC-L3755CDW
The MFC-L3745CDW has been discontinued. Customers looking for a new replacement should consider the Brother MFC-L3755CDW.
The newer MFC-L3755CDW retains the practical Print, Copy, Scan and Fax configuration while increasing print speed to up to 26ppm in both Colour and Monochrome. It also provides automatic duplex printing, a 50-sheet ADF, Gigabit Ethernet and dual-band 2.4GHz/5GHz Wi-Fi connectivity.

Other MFC-L3745CDW Consumables
In addition to toner cartridges, the MFC-L3745CDW uses separate imaging and maintenance components:
Fast Colour and Monochrome Printing
The MFC-L3745CDW delivers print speeds of up to 22ppm in Colour and Monochrome, making it suitable for everyday business documents including reports, invoices, presentations, correspondence and marketing materials.
Automatic Duplex Printing
Automatic two-sided printing helps businesses reduce paper consumption and makes it easy to create professional double-sided reports, proposals and other multi-page documents.
Automatic Document Feeder
The built-in Automatic Document Feeder allows users to process multi-page documents more efficiently when scanning, copying or faxing, rather than manually loading every sheet onto the scanner glass.
250-Sheet Paper Capacity
A main paper tray holding up to 250 sheets reduces the frequency of paper refills, while the single-sheet manual feed slot provides additional flexibility for envelopes, labels and other supported media.
Wired and Wireless Connectivity
The MFC-L3745CDW supports Ethernet, Wi-Fi, Wi-Fi Direct and USB connectivity, making it suitable for both individual users and shared office environments.
MFC-L3745CDW vs MFC-L3755CDW
The older MFC-L3745CDW prints at up to 22ppm, while the newer Brother MFC-L3755CDW increases output to up to 26ppm and provides updated networking including Gigabit Ethernet and dual-band Wi-Fi.
Both models provide Print, Copy, Scan and Fax functionality with automatic duplex printing, but they use different consumable families.
- MFC-L3745CDW: TN253 / TN257 toner family
- MFC-L3755CDW: TN258 toner family
This difference is important when upgrading from an MFC-L3745CDW: existing TN253/TN257 cartridges should not be assumed to fit the newer MFC-L3755CDW.
