Roland Soljet ProIII XC-540

It's not registering the colors correctly. Encoder strip and board are consumables. Start by replacing the encoder strip. You can flip them but honestly it's the same amount of work to put in brand new. Generic strips are about 10 bucks.

 

The bi-directional alignment and horizontal alignment is off.

 

Before you replace any parts, you should do a complete head alignment in service mode. Your print heads are seriuosly out of alignment. This will include bias - which insures the heads are straight and parallel to each other, then the vertical - which lines all the heads up with each other. Think of a squad of soldiers getting all squared up. These are both mechanical alignments, and you should go back and forth between the 2 until you don't need to make any adjustments. After these are done, you do the horizontal - which sets the head firing timing so all the heads fire at the same reference point as the first head. This is only done once. After this, you will do the bidirectional alignment, which insures the heads fire in the correct spot on both outward and return head movement, also only once. After these are done, you also need to do the user bidirectional alignment in regular mode.

The encoder strip can cause fuzzy printing and also shifting of the print between passes, creating a look similar to JPEG jaggies. It will not cause the color misregistration that I am seeing in your pics.

Do you have the service manual for this printer? All the alignments are clearly explained in the manual. It isn't a very difficult process.

Your heavy black issue sounds like a profile issue. You might want to try some other profiles and see if you get different results with the black coverage.

Let me know need some more guidance.

Like Jim Hancock said, you'll need to do all the alignments then. That's not an encoder issue in my opinion.

 

I agree it is not the encode. Did you go into service mode and do all the alignments? Bias, vertical and bi-directional's. What is your head height set to?

 

A few years back, we had a similar issue and it ended up being a pinch roller that was worn and not feeding the material in straight. Ended up replacing all the rollers, but just remember the end rollers are tapered, so pay attention to which way they are sloped if you take them off.

 

Anywhere online you see them selling service manuals they are selling something that is not theirs to sell in the first place. Do a search here on Signs101 and you will find a bunch of posts where people give them away for free.

 

About the thick black, you have of course tried another file with only 100% K on the black? Do you have for example MAX Impact set on in Versaworks?

 

Glad to be of assistance! On your heavy black, some questions. What ink brand are you using? Have you tried other profile settings? Does it do it on all your materials?
Regards,
Jim

 

Your heads look brand new, i have same printer and i wish i have the same test print. I also notice when i print text that black ink is kind of thicker. like a bit raised. It gives nice effect. No problem whatsoever with the black head
