You could give Canon a call at 1-800-OK-CANON and chat with them to see what they think.</P> Tue, 06 Dec 2016 11:46:06 GMT jrhoffman75 2016-12-06T11:46:06Z https://community.usa.canon.com/t5/Professional-Photo-Printers/Pro-100-noise/m-p/193917#M3913 <P>I just bought a Pro-100. It prints fine but constantly sounds like it is cleaning the printheads. Sometimes it will grind on for&nbsp;as much as 30 seconds&nbsp;right after I print. Any comments are appreciated. Thanks</P> Tue, 06 Dec 2016 11:02:57 GMT https://community.usa.canon.com/t5/Professional-Photo-Printers/Pro-100-noise/m-p/193917#M3913 missallpc 2016-12-06T11:02:57Z https://community.usa.canon.com/t5/Professional-Photo-Printers/Pro-100-noise/m-p/193924#M3914 <P>Mine does it periodically.
