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.
