When I print with my HP LaserJet M277 in color the whole page is colored blue. When I print in black and white a blue band covers the top of the page.

If the page is clearly cyan then in most cases it will be a failed cyan cartridge. One of the toner control blades in the cartridge is defective. HP Warrants cartridges until they reach low so if the supplies status does not indicate end of life and this is an actual HP cartridge and not a 3rd party or refill you can contact HP regarding warranty on the cartridge. They will require a copy of the supplies status page. Go to support.hp.com to find contact info.

Thanks, Repairatrooper. Your explanation made sense, so I ordered a new cyan cartridge. It worked like magic—literally. Because of the Fourth of July holiday weekend, the new cartridge has not yet arrived but my printer is working fine. Go figure.
