What does OEM mean?
OEM stands for 'original equipment manufacturer'. OEM cartridges are manufactured by your printer supplier, e.g. Canon, Epson, HP or Lemark. They are commonly referred to as 'originals'.

What is a compatible cartridge?
A compatible cartridge is manufactured by a third party source other than the original equipment manufacturer. Most compatibles are manufactured using new materials, however in some cases, due to patents etc., some cartridges are re-manufactured using the original manufacturer's components.

Are compatibles easy to install?
Compatible cartridges are installed in exactly the same manner as original cartridges.

Why should I buy a compatible cartridge?
Compatible cartridges are substantially cheaper than originals. They are engineered to the highest standards of quality and reliability with ink yields that meet and often exceed those of an OEM cartridge.

Will using a compatible cartridge void my printer manufacturer's warranty?
No. The original equipment manufacturer is not allowed to void your warranty simply because you have used a compatible cartridge.
