The PGI-2500 XL Magenta is to be used with a Maxify printer to produce professional quality documents suitable for business use. This is the XL version of the cartridge which means it holds 19.3 ml of ink making it a cost effective option for printing high volumes. The Maxify range uses DRHD pigment ink to produce printed documents of high clarity that are less susceptible to fading. This Magenta cartridge can be bought individually or as part of a set so if you only need to refill one colour you can.
