Our take
Brother describes the MFC-L3750CDW as an electrophotographic LED printer, rather than calling its imaging engine a laser. It provides color print, copy, scan and fax, rates one-sided output up to 25 pages per minute, and supports automatic duplex printing. The U.S. specification lists a 50-sheet ADF, a 250-sheet standard tray, Ethernet and Wi-Fi. The reviewed page does not give a recommended monthly page range, and it distinguishes this model from the MFC-L3770CDW, which has additional duplex document-handling features. Buyers should compare the exact model and workflow rather than transfer L3770 features.
A small office that accepts LED imaging and wants color copy, scan, fax and duplex from a networked device..
Choose another device if a laser engine is a strict requirement, if you need duplex scanning, or if a documented monthly-volume recommendation is required.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Brother lists color print, copy, scan and fax with automatic duplex printing.
- The 50-sheet ADF, 250-sheet tray, Wi-Fi and Ethernet cover common small-office workflows.
- The rated 25 ppm applies to both black and color one-sided output.
What to weigh up
- Brother identifies electrophotographic LED technology, not a laser engine.
- The source does not give a recommended monthly page range.
- Automatic duplex scanning is listed for the L3770CDW, not established for the L3750CDW.

Full review: how the features affect your choice
What the features mean for you
A color multifunction workflow with a clearly stated engine
Brother identifies the MFC-L3750CDW as an electrophotographic LED printer. It can print, copy, scan and fax in color, so a small office may keep several document tasks on one networked device. The engine distinction should stay visible for buyers who specifically require laser technology; this record does not relabel LED as laser. For people who accept LED toner-based printing, the model's functions are a broader fit than a print-only color device ([Brother MFC-L3750CDW specifications](https://support.brother.com/g/b/spec.aspx?c=us&lang=en&prod=mfcl3750cdw_us_eu_as)).
Automatic duplex covers output, not every document step
Brother lists automatic two-sided printing for the MFC-L3750CDW. That can reduce manual page turning for reports and internal packets. The ADF is a separate feature: Brother lists a 50-sheet feeder for originals but identifies automatic two-sided scanning and copying for the MFC-L3770CDW, not this L3750 version. Offices handling double-sided source documents should not assume the feeder captures both sides in one pass. Keeping print duplex separate from scan duplex avoids extending a family feature to the wrong suffix.
The feeder and tray serve different jobs
The MFC-L3750CDW combines a 50-sheet ADF for originals with a 250-sheet standard paper tray for printing. The feeder supports batches of pages for scan, copy or fax, while the tray holds output stock; their capacities should not be added together as printer input. A 250-sheet supply is a moderate reserve for routine work, but a large team may refill it often. Check the paper guides and ADF rollers on a used device because Brother's original capacity figures do not describe wear.
Wireless and wired networking are both listed
Brother's U.S. specification lists 10/100 Ethernet and Wi-Fi for the L3750CDW. Ethernet can suit a fixed shared location, while Wi-Fi can help when a cable drop is inconvenient. A networked MFP still needs compatible host software and access to the intended network, so verify that the exact model is configured for the office. NFC is listed for the sibling L3770CDW, not established here; this review does not transfer that separate feature.
Use the rated speed as a comparison point
Brother rates one-sided black and color output up to 25 pages per minute. Its specification also lists a lower two-sided output rate of up to 8 sides per minute for the L3750CDW family group. Those are manufacturer ratings and should not be read as an observed speed for a particular file or network. The reviewed U.S. page does not state a recommended monthly range, so a buyer should not substitute a maximum duty cycle or the MFC-L3770CDW's profile for missing guidance.
Check LED technology and the exact offered suffix
The MFC-L3750CDW sits near Brother laser products in retailer categories, but Brother's own specification calls its method electrophotographic LED. A buyer who simply wants color toner printing may find that distinction acceptable; someone specifying a laser engine should choose a confirmed laser model. Also check for the exact L3750 suffix and avoid importing the L3770's duplex scan, duplex copy or NFC claims. The Amazon search link uses the exact L3750CDW name but does not guarantee a current listing, included supplies or individual unit condition.

Before you buy
Is the MFC-L3750CDW a laser or LED printer?
Brother calls its print method electrophotographic LED; this review keeps that technology distinction explicit.
Does it print automatically on both sides?
Yes. Brother lists automatic duplex printing for the MFC-L3750CDW.
Does the ADF scan both sides automatically?
That capability is listed for MFC-L3770CDW, not established for the MFC-L3750CDW.
Does this model include Wi-Fi and Ethernet?
Brother's U.S. specification lists both Wi-Fi and 10/100 Ethernet for the exact MFC-L3750CDW.
