I refilled the black CLI42 cart earlier today and shortly after when I was printing out some vinyl stickers I started getting some severe smudging / ink spray and poor print quality. The refill inks and cartridges I have used plenty of times in the past with no problems. The printhead is fairly new (replaced 2 months ago) and is a genuine Canon one.<BR /><BR />I've had problems with blocked nozzles / ink starvation with previous print heads and this doesn't look like that. I'm not sure what's going on here. A nozzle check showed the issue is with the black colour only. I've run cleaning cycles but it's not making any difference.</P><P>Does anyone have an idea what the problem could be here?</P><P>&nbsp;</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="IMG_0232.JPG" style="width: 749px;"><img src="https://community.usa.canon.com/t5/image/serverpage/image-id/68785i0553E05231BB91BB/image-size/large?v=v2&amp;px=999" role="button" title="IMG_0232.JPG" alt="IMG_0232.JPG" /></span></P> Wed, 30 Jul 2025 23:14:21 GMT Rich_R 2025-07-30T23:14:21Z https://community.usa.canon.com/t5/Professional-Photo-Printers/Black-Ink-spraying-smearing-with-Canon-Pixma-Pro-100s/m-p/562354#M18602 <P>I have a Pixma Pro100s that I used good quality refill inks.
