sp 300 / problem after new pump

[groutch]

I have change to the new pump/ now i'm having some promblem with my machine. It's not getting a sharp image. It's giving me line in my image. That same image had been printed before the pump was change with a sharp image no lines. Has anybody came across a problem like mine. What can I do .

Did you try going though a cleaning cycle? I did mine about 2 mo. ago and needed to run a cleaning cycle and have had no problems since.

Just had pump replaced with the new style on my 540v
(tech instal - warranty). Required firmware update.

I think he said it was to slow the pump speed
