topic IPF6400S Print head problem in Production Printing https://community.usa.canon.com/t5/Production-Printing/IPF6400S-Print-head-problem/m-p/442865#M1180 <P>I have been using my IPF6400S to print mostly canvases for about 5 years. I have an error message telling me to replace the left print head. I have tried two new ones and both show the same error message. "Open the cover and replace the left print head." I do not think the replacements are original Canon parts, even though they have a Canon label.</P> Tue, 24 Oct 2023 19:54:27 GMT ArtisticImpress 2023-10-24T19:54:27Z IPF6400S Print head problem https://community.usa.canon.com/t5/Production-Printing/IPF6400S-Print-head-problem/m-p/442865#M1180 <P>I have been using my IPF6400S to print mostly canvases for about 5 years.
