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.

 

Many thanks,

William.

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?

Hi Kevin,

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.

Many thanks,

William.

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!

 

Thanks again!
