Printer does not print a proper testprint

You have an interesting printer ! I have two of them. Same problem. Basically to use ink refills one must have a chip reset utility. The cartridges are filled from the bottom and consequently leak if not sealed properly. The only solution is to use the blue grey plugs that come with some refill kits- Dell Refill kits have them - but only give you three. The next best is to use black electrical tape heated with a lighter then applied after the fill. What appears to happen is that the ink indicator may say there is ink but the cartridge is actually dry. Additionally I have found some new cartridges seem to have a vent problem - what happens is a vaccuum is created in the cartridge on head cleaning and a color will print, then not print , then the next one will do the same. Some brand new cartridges have chips also that the printer does not recognize. The solution is to use a chip reset tool and the old chip from the empty cartridge on the new one. There is a software called SSC Service Utility that works for deep cleaning and also resetting the ink pad counter - it will stop printing if the pad counter runs out. Basically if it refuses a nozzle check print - it is not getting ink or has no ink left.
