Are the nozels in head or ink cartidge, are they blocked if kept unused? how to compare it whit MP 180, or 190?
I want to get color printer & scanner at home. is it the best or HP better. Is it compatible with Window XP service pack 2
I want to get an ink jet color printer, there r many choices, canon mp 250. 190 or HP. Which is the best? My above question mainly about canon mp250, are the nozzles in cartridge or head and how to clean them if blocked?
I use HP printers with my computers. Nozzles tend to dry up if not used for a long time. Most printer software has a program that you click on to clean the nozzle heads. This is basically the printer heating the nozzle head to soften the clots and blows the clots out in order to clean the nozzel head. Other methods is taking the cartridge out and manually cleaning them.
