  • Smudge lines left on some prints Canon ipf8400

    I am having this problem on every print but only when printing 24x18 size poster prints - it doesn't happen when I print 24x36 - it happens in the same spots every time and it looks like the paper is coming into contact with something it shouldn't that is smudging ink on it. Any help appreciated!

    That's what's known in the trade as a head strike. The media is buckling in that spot for whatever reason and the printhead is hitting it as it passes over it. On the ipf, usually that caused by too much ink for the media, so the media cockles and that causes the buckling and the head strike.

      I had Canon ipf 3100. After having variety of problems (and incurring losses) I abandoned it in favour of Epson. Happier since then.

        Maybe so...

        But as far as I'm concerned, the ipfx400 is the best printer ever made. I have one myself and if the goal is absolute top quality, nothing else can touch it.

          Are the marks at the start of the print or near the end?

            Thanks for the help - it was the print head striking the paper - I switched from a glossy poster to a semi gloss and I think the new paper had a bit more spring to it and was why the print head was catching it - I increased the vacuum to max and raised the print head height to standard from low setting and all is well now. Thanks for info!

            Print Embellishment Goes
            Straight To The Bottom Line

            InfoTrends reported that interviews with more than 100 print customers demonstrated an appetite and willingness to pay premiums of 24% to 89% for special effects, over CMYK-only printing. They also indicated embellishment could apply to a significant portion of their work. Embellishment options can include hot foil stamping, spot gloss UV, embossing, debossing, letterpress, diecut shapes, lamination, duplex, triplex, gold foil, silver foil, copper foil, white foil, black foil, clear foil, etching, and laser cutting techniques.
