those dampers have air in try and suck the air out using a syringe from the head end of the damper, leave the ink levers down or youll get pressure.

Sorry to be a bit thick but what do you mean by ink levers down? Do you mean the main leaver where you insert the carts?

yes where you insert carts

Same outcome some cyan but not much more. Maybe time to buy some dampers and try from there.

Bugger, bugger, bugger. I now have nothing at all. completely blank. Not a line or even the text below which I have always had from the black.

Have you touched the black lines ?

no only pulled through the cyan. done a clean , nozzle check then checked the dampers again replaced cleaned and now nothing.

If its dropping out all over its more than likely the pump cap assembly

Got it back hadn't reset the dampers properly. Didn't push them on properly to busy rushing and getting worked up. Had a cup of tea and rechecked everything. But we are back to the clear checks on every line bar the cyan. Now I know this is not the technical terminology or even close but could it be the nozzle bits that the dampers fit onto. Is there a way of clearing them or is that what a pwr clean does anyway. I will get a photo of what I mean and the most recent nozzle check.

Have found my own answer. I know reaslise that is actually the rear of the head unit. So I am guessing I cant do anything there then.
