New Problem

[Jim Hill]

I fixed the problem of cross contamination with the yellow cartridge after it ran out of ink with no warning message with a new yellow cartridges and I replaced the dampers and used the syringe to draw the yellow into the damper with no problem. I also flushed the lines first.

My test print shows all all colors are printing with no drop out at all and it looks perfect.

When I print any image that should have yellow it is printing with magenta.

I just completed another manual cleaning of the heads and capping stations and I checked the dampers but they all look fine and have no cross contamination.

I have cleaned the encoder strip a few times.

I have new cap tops on the way and they should be here today.

Any idea what it might be?

dumb question, but what is the magenta printing?

 

[Jim Hill]

Sp-300

A Roland SP-300 has only two heads.

The one head is for the magenta and yellow color.

When I print any image that should be yellow instead it's magenta colored.

The crazy part is the test print looks perfect in all colors and no drop out.

Thanks Jim

Did you try printing a rectangle of each color?
(with 100% Y, etc.)

Maybe you switched the dampers, and put them on the wrong part of the head?

Print Yellow Square = magenta
Print Magenta Square = yellow

that's what i was getting to, been there...

Changed dampers

I just switched the yellow and magenta dampers and it started to print yellow and then went right back to magenta.

The New caps tops should be here today and I am thinking it must be a bad cap top.

I had removed the cap top in question and pulled the springs apart just little because it was sealing tight.

What else am I over looking?

Is there just one fuse for each head or would there be a fuse for each color?

Thanks Jim

Test Print

I will post again once the new cap tops arrive and I install them.

I even received a nice phone call from Roland Support with some very helpful idea's.

Sorry for the last very long post.

Jim,
Let us know what happens when you put in the new captop. I'd love to see test prints of CMYK.

Or get into the service menu and do a fill test pattern.

Two new cap tops

I just replaced the two cap tops.

The magenta and yellow cap top is bone dry after doing a test print.

The black and cyan are both printing perfect.

With the heads parked on the capping station can I connect a syringe and slowly pull some ink from the tube under the cap tops or will this damage anything?

I really thought replacing both capping station would fix the problem but now I am searching for answers.

Again this is an SP-300 with new dampers, wipers, scraper and now cap tops and I also installed another new yellow cartridge.

I removed one cap top at a time to make sure I put them back just the way I removed each one. I was very careful installing the springs also.

Thanks for everyone help. Jim Hill
