In October last year I purchased a Value Pack - LC47 of Ink Cartridges (Order ID 426)I have not needed to use them until now but one does not seem to working properly. It shows on the printer that Majenta is nearly empty even when replaced with new cartridge - the others appear to be fine. Could it be a"dud"one. It is Image Print with a use by date of May 2009 BarCode***36
