SC500 Printing Problem, Advice Needed
Hi all,
After a long day at the Sign Show ive came back to a problem i left hoping it had gone away but it hasnt.
I have a Roland SC500 using EcoSol Max inks that was printing perfectly until last week.
After a weekly clean it has started printing with lines through everything. When i do a test print it is fine with no drop out and also printed blocks of cyan, magenta, black & yellow and these also print okay but not mega.
I spoke to a Roland engineer today at the show and he said to perform a powerful head clean which i did and also turn the machine off at the mains then back on again and also try cleaning the white strip attached to the head or near it (apologies ive forgotten its name its been a long day)
none of which have improved the print. Ive also tried messing about with the profiles and media which does show some change but it not looking so good.Any ideas or suggestions would be appreciated before opening the bank book for an engineer to come and look at it, even if to narrow it down a little more.
Heres hoping.
Cheers
Gareth 🙄

Hi Gareth
it sounds rather like a problem i had with my CJ500 , almost as if one nozzle has kept going after the others have stopped and generated a "drag" mark.
my solution, and you probably wont like this …. or will have tried was to run a 1/2m print of solid colour K in my case through which cleared it!!! It seemed to be almost a blocked nozzle in reverse!! Good luck Hugh -
if the lines are in the direction of the head travel then check the feed print calibration has not been altered.
presuming that the sc500 does a print calibration test print set this and try again. -
Hi Hugh thanks for your advice it sounds exactly the same.
I will try this when I return on Sunday.
Chris the lines are in the direction of the print head, I’ve had a quick look through the user manual and I can’t see anything about feed print calibration, any ideas where I can find this in the menu or even if it has it.
Thank you both for your replies its appreciated I’m sure I will get it sorted, I have to.
Cheers Gareth

do you mean its leaving a black line or a white line
-
It’s leaving whatever colour the image is I’m printing, I’ve taken photos and sent them to a local engineer but he is at the show today!
Like I say just seems strange that its printing its block colours fine and the test print but as soon as an image is.sent the coloured lines start, I’ve even tried cleaning the encoder strip
-
i would have a close look at the pump and capping station as if it doesn’t clean away the waist ink , it leaves a thin film of ink on the btm of the head. which then deposits on the media.
just a idea

I will have a look at those aswell, sure I’ve got a new station in the box just in case, thanks for your time Chris.

Can you run a test in the service menu on the linear encoder check. I have had stuff get on the censor that reads the strip, and that caused lines in the print. It’s hard to see back there but if you can blow some air over or by it, you might clear it off.
Running the encoder check in the service menu will tell you if something is not right with that and at least eliminate one area.Have you replace heads lately and not changed the head rank?
I am not sure if the test prints and the solid block test prints use the encoder strip to refer to position where as running an actual file uses the encoder strip for sure. This may be why the lines don’t show on the test prints.
