Good day, Thanks for the prompt reply, i'l revise the connections and verify that the fuse is correct, i'll let you know what comes out. Thank you for your help.

Hello everyone, It looks like the fuse it burned (from my threads before), somehow it affected all the machine, looks like both light cyan and light magenta are not working, the group b fuse wasn't working, but got it repaired. The printing quality looks grainy, as if it was printed in low...

Actually I made a thread before that group b didn't print it, so they let me know that the fuse was wrong. I replaced the fuse but the yellow kept misfiring, so I replaced the yellow with the light cyan and know it doesn't misfire (it kept printing yellow on everything). Do you think that if...

Hello, I'm trying to print and doing test prints and it looks like it's needing calibration, so I went into service mode and try to print out the calibration test print but nothing comes up. I've got 2 heads that aren't working from what I see. It's the light ones (light cyan and light...

VanderJ, Here's the picture of how it comes out, i'll see if the transistors are what's wrong with it. Any other options? Dampers, cap-tops and wipers are in good condition, but I don't know why does it does that. I'll check transistors then i'll swap the heads to see if it does it with other...

OK, I just repaired the board and it works. So everything is back to normal, but the yellow ink keeps printing on top of the other colors when I do test prints. Do you guys know what's the problem? I've already changed the carriage board but not the ribbons.

Apparently the fuses look bad, could someone give me an opinion? Thanks

Thanks! I'll see what happens and let you know!

Hello, Some weeks ago I posted a question and I got helped and sort the problem out on the yellow ink. Now I've got a problem and don't know where to look for. My technician was printing normally but he says he smell smoke out of the printer, from our first thoughts was that the ink pump...

Thanks for the prompt reply, i'll do it tomorrow morning and let you know, so do I remove it and just print with the cable removed right? Thanks again!

Hello, I would like to know if someone has had this problem before, it looks that when the printer uses yellow it keeps on printing on all the colors. I don't know how to explain this. I've attached a test print picture so you know what I'm talking about. Any suggestions let me know, thanks

Hello, I'm new at this website looking for answers to questions I have about the Roland SJ-745EX. I have had this machine since September 2014, my wife and I just started a printing business and it's going well. But recently (2 days ago) I had a problem with the printer, it gives me an internal...
