Frequently Asked Questions
Can pictures and photos be printed with crisp and vibrant colors using a compatible toner cartridge?
Of course, yes! Our compatible toner cartridges are guaranteed to perform just like their OEM counterparts, so pictures and photos are printed with amazing results.
How do I know when to replace the drum unit on my Brother MFC-8840 printer?
When you start to notice a decline in print quality and it does not improve even after replacing the toner cartridge, then it’s time you change the drum unit. A ‘Replace drum’ message also usually appears on your printer panel to notify you to do so.
Should I replace the toner cartridge and the drum unit at the same time?
No. Replace only the consumable that has run out of ink or is defective.
