Have new Windows 7 computer and HP all in one 6210 and have used Scan Doctor. I can print that day, but when I come back another day to print it does not print and shoots paper through with partial print. Help, please!
Sounds like the printhead is partially blocked with old, dried-up ink. This often happens if you don't use the printer every day, especially with HP & Epson printers. Try using the nozzle-cleaning utility in the HP printer driver.
