I have a 7900 that recently started smudging the left edge when borderless printing, It appears to be ink build up and there's about a 1/8th inch wide area of wet ink as the paper exits the machine. The rest of the print isn't effected. I've never had an issue with the print quality until now. Just before this started happening I had my first head strike when printing to canvas, it's stopped the machine and bent the canvas but I finished that job with wider platen gap settings. The little pad behind the left edge of the 10" paper setting was filthy but I swapped it out with a clean one and I cleaned the nozzle wiper. I'm coming into my busy season so any advice or recommendations will be greatly appreciated!
