I've replaced both heads within the last 2 years and am now getting an error message and that the right head needs to be replaced. I print often but not commercially. Any ideas why this may happen? Thanks.</P> Wed, 26 Feb 2020 17:55:45 GMT https://community.usa.canon.com/t5/Office-Printers/IPF-6400-printed-error/m-p/297452#M10524 denjes2 2020-02-26T17:55:45Z https://community.usa.canon.com/t5/Office-Printers/IPF-6400-printed-error/m-p/297568#M10532 <P>Hello.</P><P>&nbsp;</P><P>For assistance with hardware related errors, we would have to advise that you contact our support group over the phone by calling 1-800-423-2366.&nbsp; A live agent will be able to assist you in real time and go over your options to resolve this issue.</P> Thu, 27 Feb 2020 21:09:30 GMT https://community.usa.canon.com/t5/Office-Printers/IPF-6400-printed-error/m-p/297568#M10532 Michael 2020-02-27T21:09:30Z
