Hello Friends
I am using this model of Canon from 1 year in office. Truely its not made for office use. As it is not good for frequently printouts. Color cartridge empty quikly and cant be refill. That the drawback of Canon printers. HP printers Cartridge can be refill and can be used for long time as compare to Canon.
Black Cartridge of my Canon printer was refilled only 2 times.
Also, the printouts straight line problem is coming now a days from my printer. The line and words are not straight always.
