Hello everyone who might have this problem of pages printing blank. Although I had done numerous nozzle check cleanings (which all the colors printed out perfectly), I didn't realize there should've been a black mesh design above the blue line on the printout.
I talked with a very kind (and patient) representative today and he suggested that I do a DEEP CLEANING. That did the trick. I've had my G4210 printer about 6 months and I don't do heavy printing, so if you have this problem and the black mesh design doesn't print in your nozzle check print, DO THE DEEP CLEANING! I have made a note in my printer folder so I have reference in case this happens again.
