printing problem on seiko 64s colourpainter

[mario]

Hi,

Does anyone experience this kind of printing? (attached) It does it occasionally every 2/3 m run of printing. I think its a capping station, but cables to heads looks clean, and heads are working fine except the light cyan and light magenta not top condition but is this related? i dont think so...

I never seen anything like that before, you sure there isin't another file with in the file your printing?

Its a tiff file. I will check saved prints by the way.

Hi what rip software are you using?

Not very known to this machine but looks like encoder or encoder strip problem to me

I use photoprint with its rip software. The printer worked fine when i cleaned the cables attached to the heads as there was some dry ink. Thought i solved it but it making it again today.

I have an HP9000s which is probably the same. It's a clear strip about the upper track
where the printhead bearing rides. YOu wouldn't know it was there unless you were looking for it.
I was having some strange print issues which didn't make sense. I think is was some sort of banding perpendicular to the printhead direction if I remember correctly and wiping the encoder strip lightly with a soft lint free cloth dampened with 99% isopropyl alcohol.

But DON'T do anything without confirming the alcohol thing. It's been over a year and I don't necessarily trust my memory on that.

Thanks Bill for that tip! i will try that tomorrow.

Is it safe to clean with capping solution?

Is it safe to clean with capping solution?

If you're talking about the encoder, no. You should use something like 70% ipa and a lint free cloth to clean the encoder.

I'm not sure if its that plastic stip along the way at the top of the carriage, where there is a sensor reader to it. I cleaned this and cables attached to head and edge of cables to the board and is working fine now. Hope that was it.

thanks friends for your tips !!!
