HL-4140CN

Add wired networking to the 22-ppm color engine and you get the Brother HL-4140CN, a 10/100 Ethernet printer built for shared office use. It holds one notable quirk: despite the CN badge, Brother's spec sheets confirm there is no automatic duplex here — two-sided output stays manual. With 128MB of memory and 2400x600 dpi resolution, it handles color documents crisply, and TN310/TN315 compatible cartridges make its running costs easy on the budget.

Frequently Asked Questions

Which toner does the Brother HL-4140CN use?

The HL-4140CN uses the Brother TN310 standard-yield toner series (black ~2,500 pages, each color ~1,500 pages) or the Brother TN315 high-yield series (black ~6,000 pages, each color ~3,500 pages), paired with the Brother DR310CL drum unit (~25,000 pages).

What is the difference between the TN310 and the TN315?

Both fit the same printers. The TN315 is the high-yield version — about 6,000 black / 3,500 color pages versus about 2,500 black / 1,500 color for the TN310 — so it costs less per page if you print a lot.

Are the cartridges on this page original or compatible?

Both — this page carries compatible TN310 and TN315 replacements as well as genuine Brother OEM TN310 and TN315 toner cartridges and the genuine Brother DR310CL drum.
