I'm sorry about the issue. Do you mean the model MG6320 (not MP6320), or is it another model?
Was scanning working fine previously? Is there any error or message?
Is printing currently working fine?
Do you have windows xp, vista, or 7, or 8, 10, or mac computer?
Can we do a remote support session, so I can troubleshoot the issue directly on your computer together with you?
Please reply at the box below. Thank you,
After scanning, do you see the scanned file in your Documents or Pictures?
Is there a program called (Canon) IJ Scan Utility on your computer? If yes, what happens when you use that program to scan?
