How to install it
- Open the front cover and let the printer cool for a few minutes if it has been printing.
- Pull out the drum and toner assembly together, then press down the green lock lever and lift the old cartridge out of the drum.
- Unpack the new cartridge and rock it gently side to side five or six times to spread the toner evenly.
- Slide the new cartridge into the drum until the lock lever clicks.
- Slide the green tab on the drum from left to right three times to clean the corona wire, then return it to the home position.
- Put the assembly back in, close the cover, and print a test page.
If something goes wrong
The display still says replace toner
Brother printers count pages rather than measure toner, so the message stays until the counter is reset. Open the front cover, hold the control panel steps for your model, and the count clears.
Full guidePages come out blank or very light
Nine times out of ten the sealing tape is still in place or the cartridge needs rocking to spread the toner. Pull the cartridge, check the tape, rock it gently, and reinstall.
Full guideStreaks or a repeating mark down the page
Streaks usually come from the drum, not the toner. Clean the corona wire if your printer has one, and check the drum count before replacing the cartridge again.
Full guideQuestions about the DR350
How many pages does a DR350 print?
About 12,000 pages. The rating follows Drum yield is approximate and varies with pages per job.. That is a rated average, so heavy graphics use toner faster than plain text.
Does a compatible cartridge void my printer warranty?
No. Under the Magnuson-Moss Warranty Act a manufacturer cannot void your warranty just because you used a third-party cartridge. If a cartridge of ours damages your printer, our printer damage protection covers the repair.
What if it does not work in my printer?
Send it back. Returns are open for 90 days and that includes opened cartridges that are defective. Shipping is free both ways.
