Stafford Cox is your man to speak to.
I have same machine but never had that problem, sorry

How old is the machine, my 1st point of call would be to change the dampers & capping station

Hi Kev

The machine is about 9 year old, had new printhead fitted by Hybrid a 3 years ago, in the time I’ve had it it not been heavily used, but cleaned regularly.

I myself thought it could be the dampers or pump? the problem its very odd, I can do test print one minute and all seems to be ok, then after doing a print job if i carry out a test print it shows large sections of colour banks missing??

I’m going to order 8 new dampers tomorrow and a pump to see if that cures it?

I’m still open to any other ideas that anybody has to what the problem could be?

Many thanks.

I would say damper, but on that age machine i would treat it to new dampers & camping station, bad seal on capping station would show up as a pump issue

Hi Kev,

Thanks for the reply,

I replaced the the capping station few weeks back with no noticeable change, I will replace all the dampers this week and pump and ill see if it cures the issue?

Regards

without teaching you to suck eggs did you ensure it was sealing & id you have the issue before or has it occurred afterthe swap

Hi Richard.

I’d go with dampers first, too. The fact you can get the nozzle test back from cleaning would suggest to me that the pump and cap are doing their job. I only use/sell genuine compression dampers on these machines as generic ones have proven temperamental in my experience. Just replace the ones that need replacing though.

As for overspray, it could be anything. Pictures say a thousand words in these situations. Post some up and I’ll see if I can help.
