I have a genuine HP Cyan cartridge Q 6001A which seems to be spitting out toner on the the paper. It is also leaving a streak of blue toner on the LH side of the film roller. How long does HP warrant the cartridges for? I bought the printer from a friend who went back home from Bangkok where he was on assignment so I don’t have a receipt but I have the printer report saying that it still 85% full. Would there be anywhere in Bangkok where HP would be able to look at it and hopefully replace it?
