Frequently Asked Questions
My Brother MFC-8840 now uses a compatible toner cartridge. But recently, I noticed some dots on the printed pages. Is the compatible cartridge the culprit?
That's very unlikely. Dots on the printouts are often caused by a foreign material inside the machine (such as paper dust, staples, or glue from envelopes or labels) damaging or sticking to the drum's surface. When toner sticks or builds up on these areas, black dots are created on the printouts.
Are the toner cartridge and the drum unit replaced at the same time?
Not necessarily. The toner cartridge and the drum unit are two separate consumables. When one consumable is damaged or depleted, just replace it and leave the other one as is.
Is it possible to place my compatible toner cartridge offline?
Yes, absolutely! Our Customer Service Department is available from Monday to Friday between 7:00AM and 5:00PM. Just give us a call at 1-888-679-9416, and one of our friendly customer service representatives will be more than glad to assist you in placing your compatible toner cartridge order.
