Black bleeding into red

[jus.hila]

Hey guys...just wondering if anyone knows what the problem may be with my Roland sv300i.
When it prints red it print solid and half way through a large print the black starts bleeding into the red (see images).
I've tried manual clean and numerous cleans and it goes back to printing well. Half way through the print the black starts bleeding into the red again. Any help would be greatly appreciated.

Any chance of providing a nozzle test print? The print itself doesn't look to be clear

Here's a test print. It doesn't look too bad. Black only starts bleeding half way through the print.

Print until the black banding is really bad. Then - without doing a cleaning cycle - immediately do a nozzle test print and post it please.
