MP990 Streaking photo

[gooch]

When I print a Jpg on the MP990, I get streaks in the photo as shown below. I have tried Clean and Deep Clean and I notice a slight improvemnet after the Deep Clean. Is there anything else I can do or should I keep trying the Deep Clean?

Before I started working on this, I did a nozzle check and everything looked okay and the pattern looked fione with no streaks. Now after trying various options, the nozzle check is only printing the PGBK, BK and G but no C, M or Y. Any photo I print now is in gray scale with no streaks. I must of changed a setting to lose the color somewhere but don't know what. Any ideas?

I must have turned the color off when testing. Turned it back on and ran the Clean on the color cartridges 4-5 times and every thing lookls good now.
