Roland SP300v printing issues

Hi all,
New here!
I’ve joined to hopefully get some advice about a printer I have just purchased.
It’s a cadet printer which is running as a Roland SP300v.
The person I bought it from says it’s just been serviced and recently had a new head but I’m having some problems.

Basically:
The print quality is very poor. There’s a section missing from the M and Y section of the head print. The C is pretty much perfect and the K has some missing nozzles.

It will print but there is banding, fuzzy printing and if it prints anything substantial the black will begin to turn green.

Just wondered if I could get some expert knowledge here, I’ve performed a couple of head soaks using Roland cleaning fluid, I’ve cleaned the cap tops and the wiper and tried a load of different profiles to print from.

When first printing everything came out very faint and no colours, I found some air bubbles in the lines so I’ve removed these using the cleaning functions, it’s had a couple of powerful cleans and some medium ones as well as just using the cleaning button on the printer control panel.

I’m printing from versaworks 5.

Thanks for reading

 

Hopefully these images show the latest head print as well as an image of a bi directional print and a uni directional print. Also a print I did the other day before the 2 logos which show the black with the fuzzy printing. The logos show some of the banding issues and droplets that can be seen within the white text. I’ve made some progress with this over the last few days but I’m beginning to run out of ideas and hoping it isn’t the head, obviously! On another note does anyone know of a Roland engineer that covers Tamworth?

Many thanks

 

Thanks. There is no obvious damage to the head surface. Is there a way to check the cap tops or is it just a replace them type of job? When I put the cleaning fluid on them it drains away after taking the clip off the drain pipe when I do the head soak.
I’ll have a look in to that ultra sonic cleaning aswell.

 

Great I’ll have a look in my service book and find where I need to disconnect and give it a go. If need be I’ll get new caps

 

Thanks. It’s a shame as the guy I had it from told me it had a new head recently and a big service. I’m beginning to think that isn’t the whole truth. I’m hoping I don’t need to replace them both. I can probably stretch to the yellow magenta head but if both are shot I will need to rethink my options with this machine I think

 

Yeah it’s probably going that way! Best I’ve found one here in the UK is approx £450, then it’s fitting it.
I haven’t tried printing in high quality I’ll give that a try and see if it makes things any better, in the short term at least.

 

I’m clamping the drain tube going in to the bottle, take bottle off and clamp the tube then put bottle back on. That will work ok?
It’s had about 9 hours today so I’ll check it when I get back and see if it’s any better. Most it’s had before is about 2 hours so I’m really hoping!

 

This is a print done just on high quality. Using the generic vinyl 2 setting in versaworks. The cut path is way out but I can’t use the normal marks as I get an error to do with the sensor, but it’s the quality I’m more concerned about at the moment.
I don’t think this looks too bad compared with what I have been getting.
After the 9 hour soak a couple of nozzles came back on magenta but there’s still a sizeable block missing.

 

It’s certainly a lot to get used to. The logo that’s printed is looking very close to how it’s designed which is much closer than it was before. I’ll give it an overnight soak and see if it brings back anymore nozzles. Thank you to everyone for advice so far, it’s very valuable.

 

Ok so it’s definitely a head job.
I’ve just done another test print which I’ve attached, I’ve also managed to get the flashlight from my phone under there and I can clearly see head damage on the magenta yellow head in the area of the issues I’m having with the missing nozzles. Damn it! Need to figure out why the blacks missing nozzles now too...or maybe its 2 new heads....hoping not! I don’t think my light was strong enough to see this damage the last time I looked!

 

So much has happened since I last posted here.
I ended up throwing 2 new heads in there.
The black head fell apart in my hands when it was removed!

I’m having some banding issues on magenta prints at the moment that I’m trying to sort but other than that it’s a hundred times better than when I picked it up.
