One Colour Smudging

[Prograf]

One colour is smudging on my Canon Image Prograf printer. I have printed out a test print which clearly shows all bar one colour printing fine.

Does anyone know if this means that the head needs replacing?

Not sure what you mean by smudging. Can you take a picture or do a scan and upload it so we can see what you mean?

Also, can you do a nozzle check and upload that too?

Hi. Thanks for your reply. I am new to this forum and not sure how to attatch a jpg of the Nozzle check?

It's easy to describe tho', basically where the nozzle pattern should show several sets of vertical twin parallel lines for each colour, it does this for all colours except Light Cyan. The Light Cyan has one perfect twin and the rest are progressively less sharp and spread out. As if the nozzle is 'blown out', which I am guessing is what has happened.

However there are several nozzle check patterns to print and the most common looking one, rows of staggered horizontal lines, all colours perfect except Light Cyan, which has about 25% of the lines missing in patches. No fuzziness just gaps.

Also, when I moved the printhead to check it some Cyan, probably Light Cyan, leaked on to the platten.

Look forward to hearing your views.

You can find instructions for uploading here. However, I would suggest that you rescan your image as a bitmap so that it doesn't lose any detail like happens with jpegs. Use the highest resolution possible. Then open the image in Paint and crop it so that it is just the size of the nozzle check and then resave it as a .png. Finally upload the .png version of the scan.

That up-load system flumoxed me! There was no code after up-loading the image, just a 'Thumb' and 'image' URL or something like that?

I think my description was fairly clear, sorry. Don't worry if I haven't been clear tho' because I've just ordered a new head! but I am still keen to have any opinions or shared wisdom. Many thanks!

Just copy the text in the 'image' display and paste it into your post.
