The amount of ink available for printing depends on several factors: the printing habits and how the printing system uses ink to print pages while maintaining reliable performance. Generally , printers used regularly consume less ink for cleaning. Compared to print jobs close, print jobs less regular require maintenance procedures more aggressive for the nozzles of printheads. These procedures more aggressive use more ink. The maintenance procedures can also be triggered by other events, such as the amount of ink used and the relocation of a cartridge that has not been used since long.
