You can re-calibrate the sensor in service mode. A lot of people just put tape over the sensor so it thinks it always has media. Just be aware that this introduces the possibility of the media actually being at the end and it will print on the platen until you notice it!

Usually when you can see the nozzles messed up like that it's physical. With electronic failure it usually either prints 100% no matter what is printing, it doesn't print at all or the nozzle check will look perfect but still print fuzzy edges. That being said, I have seen a few heads fail...

The only way to fry the board on the head when cleaning is if you get cleaning solution on it and then don't let it dry before powering up. Usually if I get solution on a board I clean it with 90% alcohol and then let dry just to be sure. You can also damage the head physically when trying to...

Merchant memberships are cheap and easy to setup on Signs101.

If it's a rumbling/humming sound, the motor voltage might need to be adjusted. I don't know if you can do that on a Roland but I do it on Mimakis once in a while.

The needle part number is 1033462. Hope that helps!

Chasin' that SEO!

Guess we'll have to disagree. I wasn't saying anything about latex. Just that Epson based eco sol heads do not fail sooner than HP ones that are consumables.

I don't doubt your experience with your machine. I have fixed 100's of printers and helped 1000's of people fix theirs. If your head degrades after one print something is majorly wrong. I have people who have gone 10+ years on a single head!

Not sure who told you this but it's not true. Sounds like an HP sales gimmick!

It comes free with new printers. Normally used printers will come with it as well but in the cases that the seller doesn't have it, you would have to purchase it. The free download is just a 30 day trial until you put the password in.

It's a creative idea for sure but I can't tell you either way. You would definitely need to turn off color correction for it to work but it's not something I have ever tried. If you do try it out, let us know how it goes!

Unfortunately no. The head on that machine is configured specifically that way. To change the color order you would need to be able to edit the firmware.

6 billion for each line. Usually magenta and yellow will hit that mark first.

DX7 heads with solvent inks usually last 3 to 5 years depending on use. The official life is 6 billion fires. If you don't use it a lot that can make it clog faster but usually a cleaning will bring it back. Have you changed the cap top yet? It should be changed once a year. Also, machines that...

I'm pretty sure Rolands use the GPGL programming language. If you can create some code that turns your design file into GPGL code you should be able to send it directly to the plotter. Never understood why Roland does things this way. Every other brand of plotter I have used lets you cut...

It could be the material in that case for sure. Do you have another material to test?

Trying to help a customer out and can't find this manual anywhere. Mimaki won't give me one because I am not officially trained on it!

Usually in these cases it will print a low resolution, non-variable dot profile fine because the biggest dots are easiest to fire. The higher resolution, variable dot profiles will print like you are seeing because the head isn't quite firing properly. The biggest dots are used in the test print...

In my experience that is usually a sign that the head is failing electronically. Even when the test print looks fine it can be having issues. If the head is 5 years old or more that is what I would suspect. You can also print out the service report and see how many fires the head has. If there...
