How let Lexmark S305 only use black cartridge to print black. Now the color cartridges getting empty by only printing black, and with "only use black ink" selected. (Besides that, the cartridge can print much less pages than what it says on the package, not 500 pages but at most 100 text pages.) People say you can install some software for that, but I can't find it.

When any printer starts it goes through a cleaning stage it uses color ink and blank ink to purge the heads of dried ink this is done by sucking ink through heads doesnt matter about settings in windows this normal mechanical function of printers in general.
