You didn't tell us a whole lot about your printer. What is the make and
model of the printer?
Did you replace an ink "tank" or a cartridge with ink and head built
together?
Did you follow the mfrs. instructions or just replace the ink cartridge?
Some printers have an "ink charge" cycle that must occur.
Was a built in head dry for some time before you replaced the ink? (If so,
it may need unclogging)
Is an indicator light blinking on the printer? If so, is there a repeating
pattern to the flashes?
