Harvey Head Cleaner will NOT unclog a printer.
Harvey will prevent clogs from occuring in the first place. Inkjet printers clog up when they're not used. Harvey keeps printers in shape with a regularly scheduled workout routine.
So clogs just don't happen, nearly as often.
Harvey allows the user to schedule regular print jobs resembling a nozzle check. These patterns are designed to use all nozzles, with minimal use of ink.
The recommended schedule depends on the type of ink being used and the environment of the printer.
This small program sits in the background and awakens the computer to get a small print job done.
Harvey is for use in Windows - Windows 2000, XP, Vista and Windows 7.
