Need Help SP300i new problem occurs

[Eric Lemay]

Hi !


Since a month or two I have problem with my prints. The darker colors are affected, I mean those using black ink. Bright colors don't have those lines (as you can see on the picture below).

The black head has been changed 1 year ago. Last summer, I changed the wipers and the captops. In the same time, I also removed the encoder strip and cleaned it with acetone. I didn't change the dampers and I don't know the last time they have been changed.

I did a print test and everything is beautiful. I also went into the service menu and printed solid stripes of the 4 ink cartridges. The black was solid, no lines as it appears on the picture below.

This print is on a oracal vinyl. When I was printing on Roland photo paper, that was not happening, but since a few days, those line appears on this paper too.

Should I change the dampers ?

Thank you !

Have you tried a bi-directional/feed alignment?

Check for lint/hairs on the heads and cutting knife

I would say a bi-directional adjustment is probably needed. Also, do you have a picture of the nozzle test print?

I'm always printing Unidirectionnal !

Hi !

I never use the bi-directional function. I'm always printing uni-directional. Here's a picture of my test print:

Have you tried playing around with the profile settings? Are you doing a high quality print or just standard? Also you could play around with the speed and heat, but I think it could be partially an alignment thing. Have you done a Calibration recently to make sure the feed gap is correct?

Yes I tried many profile such as many papers. This was happening first only on vinyl, but then appeared on photo paper and t-shirt vinyl. I didn't do an alignment yet, that's a good idea to check this out.

Any luck after doing the alignment?

Yes. I tried many feed adjustments with the head calibration. It didn't change anything. This night I will perform a head soak until tomorrow.
