Ink "Spreading" on Roland SP540V

[Chris Wool]

any defection in the head print test
static – have you used a all plastic media lately
bi-directional settings need re-calibrating
main head alignment out

enjoy

Thanks for your help Chris. I have been tied up with clients all day. The head print test looks fine. My media is the same vinyl I that I have using for a long time. I have done bi-directional calibrating but I am still getting this Magenta "light spray" in the white areas when I print a solid navy label. I will contact Roland tomorrow. Thanks.

Too low humidity may also cause spreading, although it should show with every colour.

Thanks Otto. If you look at the following link, you will see a photo of the problem.

I hope this helps!!

Got the same machine as you Noel, in my experience one of two things would cause this sort of effect;

Head height is set to the high position, drop it back down and try again
or
Build up of ink residue around the head, give it a clean and try again

Also do the bi-directional setup which will probably help too

seen the pic my bet is static as it covers quite a area

I thought that Chris by the way it is scattering, but how come only magenta is scattering, makes me think that the head on the magenta has got some sh!t on it of some kind, maybe wipers and head need good clean.

Strange that it’s just the magenta colour that’s causing a problem. Could the magenta ink itself be at fault?

[Martin Oxenham]

I have exactly the same problem started yesterday with black. Its like a shadow around the colour. Have done a powerful clean and a manual clean as the test print had loads of squares missing. But after the cleaning the test print is almost perfect, but the problem is still there. I have tried wiping the head gently with cleaner as well. Have sent photos to Roland and waiting for a reply. The maintnance contract runs out in a few days so depending on the outcome will decide weather we change to another contract provider.

take a magnifying glass to it and would expect to see other colours as well
it was black on my machine when it happened but there was traces of other colours.
the wipers may not be doing its job to well then alowing the static to disperse the waist ink on the btm of the head.

this fault could go as quick as it came.

Thank you guys for all your contributions. I think I will change the wipers and give it a complete head cleaning.

I will let you know if I solve the problem.
