4 Things to Know About the Brother HL-L2390DW's Engine

The HL-L2390DW uses the same TN-730 engine as the entire HL-L23xx line. This means performance and reliability are consistent across the series.

It accepts two toner cartridge options. The standard-yield TN-730 prints 1,200 pages, while the high-yield TN-730XL prints 3,000 pages.

The printer uses a separate toner-and-drum design. You replace only the toner when it runs out, and the drum unit lasts much longer.

This architecture keeps replacement costs predictable. You avoid paying for a new drum with every toner change, which saves money over time.
