This may prolong Uniform head life.
I had someone in to create some profiles for me yesterday, he works at a supplier local to me and yesterday Roland where in to up there dealer status yesterday and the guy doing the profiling for me is a trained Roland engineer.
He had a look at my machine and the only comment he made was about ink on the top of the heads, he showed my a defector over the heads that is black although it started life clear. What he says has caused this is that Roland printers have what he called a "spit tank" this is basically a square bowl with a pipe to the waste bottle that the heads fire ink into on every pass , what i have been told is that on a Roland machine these have a sponge in them, B&P sometimes remove this sponge as Activasol cause it to expand and hit the heads. The effect of removing the sponge is that instead of the head firing the ink into the sponge it sprays it into mid air as it is 15m/m to the bottom of the bowl and the head’s only fire ink a couple of m/m, the problem is that with the ink in mid air and the head moving backwards and forwards causing turbulence the ink get blown around hence the area around the capping station and all of the heads get covered.
The engineer suggedted that i buy value scourer from Tesco cut the green side of and use this as he has had good results with this method.
All of what he said made sense so i have been to Tesco today and made a sponge because there is a fine covering of ink on my machine.
I thought i would share this as other Uniform printers may be getting excess ink on the print head boards because of a lack of sponge.
Best regards
Russell.

Is that the sponge in front of the wipers Russell. I have a cadet plus so may be a bit different.

Hi Steve,
Yes on my machine it is in front of wipers and just top left of capping station.

Mine has a sponge in but needs replacing as it has stopped being spongy and if you bent it it would snap. Will have to try morrisons scourers as we don’t have a tesco. :lol1:

Nice work Russell, if you can post a picture then please do or just send it to robbie rob@uksignboards.com and he place it here. Like to see your wiper assembly a bit more… there is a spong on the JV3 but not how you decribe it.

hi Russel yes that is a problem i spotted 4 years ago. as the sponge was hitting the head.
i over came it by fitting a new sponge with a gauze over the top.the gauze was the type used with car filler found in car accessory shops cut to fitt under the silver cover but on top of the sponge. stopping the sponge from expanding.
