Answer to: Printer won't print in black. What's wrong?Change the printhead. Dont waste anymore time. Order one from amazon for 17$. It was a risky move considering the printer didnt have much value left as it is old (kodak hero 3.1) but now it works like new! Im sure buying the cheap ink cartridges isnt the best thing for the printer but hey now i will hopefully get a few more years!
