Why is it saying there is a problem with the printerhead?

"Susan Costello, You did not state your model#, Start your trouble shooting of print head error using the links below. In some forums they say if you contact HP they may replace the printer as this is a known issue for some models to have a bad print head, may be worth looking into. If under warranty and no go, return for replacement/repair/refund. Good luck. I hope this helped you out, if so let me know by pressing the helpful button.
