VP-540 print quality printhead replacement advice HELP!!!

[sydster]

Hi Guys,

I'm having quality issues,

1. Banding/white gaps on CYAN
2. Banding/white gaps and over spray on Black

I have purchased 1 new printhead but not sure which to replace, Cyan or Black, does on look better than the other? Can one be recovered to better state?

thanks in advance


also would anyone have a link for service manual or any instructions for head replacement.

The black. Both seem to have deflected nozzles but the cyan nozzles seem to be still aligning quite well horizontally (on the pic) while the black seem to have more of a "wave" in the upmost row. Just a stab at it, both seem to need some work (or replacement) at least, I assume you have tried head soaks?
Another point to consider is that if you print for example black text or something you usually see banding quite fast if you have a bad black head, but the color heads are more forgiving. Just my .02 here... Good luck!

, I assume you have tried head soaks?!

no haven't tried head soak, is it a function on the printer or will I have to remove head and soak with head cleaning solution?

It's not a function in the machine, you manually fill the capping station with cleaning fluid and let the heads soak for a while, the process is described on this site in some threads... The head soak could improve the pattern a bit but it looks like you've had a head strike at some point?
