https://community.usa.canon.com/t5/Professional-Photo-Printers/imagePROGRAF-iPF8400-lines/m-p/191402#M3844 <P>I have a customer who is experiencing wavy lines on output that does not have solid color (2 images attached). Both A and B printheads have been switched out. The maintenance kit has been changed. I suggested a new suction fan, which I changed today.&nbsp; I have no idea what's causing this. 16,000 sq ft printed on the device. Any ideas?<IMG src="https://community.usa.canon.com/t5/image/serverpage/image-id/11672i692FB5550BCE389A/image-size/original?v=v2&amp;px=-1" border="0" alt="Canon imagePROGRAF iPF8400" title="Canon imagePROGRAF iPF8400" /><IMG src="https://community.usa.canon.com/t5/image/serverpage/image-id/11673i8461EFF89B8DCC85/image-size/original?v=v2&amp;px=-1" border="0" alt="Canon imagePROGRAF iPF8400 -2.jpg" title="Canon imagePROGRAF iPF8400 -2.jpg" /></P> Thu, 10 Nov 2016 01:00:47 GMT czubad 2016-11-10T01:00:47Z https://community.usa.canon.com/t5/Professional-Photo-Printers/imagePROGRAF-iPF8400-lines/m-p/191402#M3844 <P>I have a customer who is experiencing wavy lines on output that does not have solid color (2 images attached).
