https://community.usa.canon.com/t5/Desktop-Inkjet-Printers/Pixma-MG6470-black-ink-stripe-problem-paper-doesn-t-feed/m-p/149690#M39990 <P>Hi, I bought a Canon Pixma MG6470 last year, and everything was working fine originally. However, after around 3 months of non-usage (vacation break from my university, so no printing of notes for me), the printer started to act up. The paper wasn't feeding properly, and the black ink (only black, which I don't know why) causes stripes in the printed material. I've attached two pieces of test print which shows the problem I am having. In the color test, the black ink prints with stripes and not the other colors, while in the printed Nozzle Check Pattern, the black portions are blurry. Can anyone with knowledge on these problems help me with this? Thank you.</P><P>&nbsp;</P><P><IMG src="https://community.usa.canon.com/t5/image/serverpage/image-id/7948i52D6C10578767AC1/image-size/original?v=mpbl-1&amp;px=-1" border="0" alt="IMG_20150824_0002-min.jpg" title="IMG_20150824_0002-min.jpg" /></P><P>&nbsp;</P><P><IMG src="https://community.usa.canon.com/t5/image/serverpage/image-id/7949i6AD9E802B5131455/image-size/original?v=mpbl-1&amp;px=-1" border="0" alt="IMG_20150824_0003-min.jpg" title="IMG_20150824_0003-min.jpg" /></P> Mon, 24 Aug 2015 06:27:41 GMT wayne_9x 2015-08-24T06:27:41Z https://community.usa.canon.com/t5/Desktop-Inkjet-Printers/Pixma-MG6470-black-ink-stripe-problem-paper-doesn-t-feed/m-p/149690#M39990 <P>Hi, I bought a Canon Pixma MG6470 last year, and everything was working fine originally.
