Please see attached picture.
This has suddenly started happening where in the middle of a print, roughly at the same point the head seems to hit the paper.
I am using Hahnemühle Museum Etching 350gsm paper – which I have uses without problems for years now.
The head height is set at “Highest” and the vacuum strength at “Strongest”.
Any suggestions or information will be greatly appreciated.

A couple of questions . . . is this a one off or does always happen now? Which direction is the paper going? On a long piece of paper does it repeat? These help us to see if it is a head issue or roller issue. If it is repeatable how much distance between repeats? Does it happen with other papers?Re: Canon iPF8400Reply #2 on: August 1, 2023 at 8:56 am
It started immediately after a head replacement…
I was making a 914mm x 1530mm print and it first started after about 300mm(24″)….then it did it a few times at about double that distance. I was then able to make a 914mm x 1530mm and immediately after that a 914mm x 1330mm print without a problem. All on Hahnemühle Museum Etching 350gsm….
The next day I made two 610mm x 664mm prints on Hahnemühle Photo Rag 305gsm and it made a slight mark on the first one…second one fine!
Always on the right-hand side of the machine i.e. the side where the print-head carriage rests. The outside borders were perfect.
Each time just once.
Shout if you need more information.

Quick update: based on Kevin mentioning “roller”, I reset the “Roll Tension” from “Standard” to “High” and then printed just over three meters without a problem. It was on 305gsm…we will see what happens when I try the 350gsm!
