Grainy Prints on Roland

[All Star Graphics]

We're print vector files for a wrap. The Cyan cartridge ran dry with no warning. Replaced and reprimed, the Roland is printing very grainy. ANy ideas? Thank you in advance

Does the Nozzle Test look good? What head height setting? What media and profile? What software RIP being used?

Just ran into the same thing, fixed it with a humidifier and head height adjustments. Hope yours is as simple. It got so bad before adding humidifier that we thought we had a damaged head

if you completely ran out of ink while printing .. you got air in your line use a syringe to bleed the line.

Why no warning? You may have your machine set to continue printing when the cart is low. I dont let it do that. When cart is low..I get a heads up , replace cart..and carry on.
Cheers!
