Maintenance: Keep the print heads clean and avoid risk of blockage

Always ensure that the print head is kept clean in order to stop ink clogging in the print head. Some machines, mostly the Hewlett Packard printers, have a tendency not to clean the print head properly as part of their normal cleaning cycles. Often deposits of ink will form on the end of the print head causing the cartridge to function sub-optimally. This problem can be fixed by gently cleaning the print head with a soft cotton ball, cloth or clean tissue. Snap the cartridge in and out a couple of times to get a good connection after cleaning. Keeping the print head clean also greatly increases the number of successful refills.
