Weekly Tip No 48 - Never test your cartridge this way

NEVER EVER EVER put a different color cartridge in one for another color to see if the cartridge is the problem. Always replace a questionable cartridge with the SAME COLOR. Why? If you put a different color in the wrong cartridge slot, it will contaminate the flow-through sponge that delivers the ink from the cart to the ink-jet head nozzle. Once you do that, it will require running a gallon of ink through the delivery sponge to get the wrong color out.
