Can you hear the pumps pumping? If so, purge any working color for 5-10 seconds. Listen for the pumps. They probably operate with short burst. How many "pumps" did you hear? Now purge your black. How many pumps? If your working color gets like 2 pumps and your black gets like 10 or so before...

A second air hose right? Sounds to me like you have one for negative pressure and one for positive pressure(purging). Trace both of those lines to their end opposite the subtanks and tell me what they are attached to. If the line you removed was the negative pressure line then ink would weep...

so when you take the hose off of the top of the tank is air blowing out. It should not be. There should be a regulator that would only allow positive air to push into the subtank when you are purging. This air is what forces the ink out of the heads. There should be a solenoid to regulate...

Also does your machine automatically wipe or do you have to manually wipe the heads after a purge? Regarding your other thread, if your printer uses positive air pressure applied at the subtanks to purge, then you should be able to see ink weeping from the heads as you run a purge. If there is...

So your printer has subtanks right? Was it a capsule filter and an inline filter? Does your printer use air pressure to purge and have a negative air pressure line?

Our qs is pretty solid. Its a 2006 I believe and its nozzles are about 99 percent. On its fastest setting it runs around 14-4x8 sheets per hour. This would be 4 pass bidirectional. We use this setting about 20-30 percent of the time. Our standard setting is 8 pass bidirectional and its closer to...

In my experience an error relating to the pump usually means that the pump has timed out. When the pump is told by the printer to turn on, the pump only activates a certain number of times before timing out. This would mean that the pump could not get enough ink to its desired location within a...

The vutek heads pretty much never go out. I'm not sure if your looking at new or used printers but Global Garage has a used 2013 vutek gs3250r for $225,000. You wouldnt need any special materials for this machine either. I've never actually operated one but I have been operating a qs2000 for...

Regarding the ink pumps, what I meant to say was where are they located? Are they under the capping station or next to the primary ink tank?

So are you saying that you cant get the magenta ink to the head? Does this machine have secondary ink tanks (sub tanks). I assume there are ink pumps on this machine? What about filters? I googled Mutoh Toucan Hybrid and found this same thread on several other printing forums. I'll try to help...

Does the printer ask for a sheet size or does it scan the material to figure out the size?

Can you describe the ink system in your printer? Are there subtanks? Ink filters? Pictures would help as well. I couldn't find any useful information on the internet about how this printer is set up. As others have mentioned it does sound like a damper issue. Its hard to say what else it could...

We have been using www.sign-in-china.com for pretty much any part we need that they carry. They have lots of parts for mimaki and mutoh. We buy our dampers from them for our vutek flatbed (seiko heads). One of these dampers cost us about $400 from a company that services our machine. We bought...

I dont think there is any way static can keep a printhead from firing. Not without frying it at least. Does the software on this machine allow you to look at the printhead temps and voltages? If its not firing because of a connection issue I would think the temps and\or voltage readings would...

The best process to use for backlit signs in my opinion is called a three-layer white using a vutek printer. Say your print is solid red with white letters. The first layer would be your print on single pass. The second layer would be a flood white. All of the red in the print would be covered...

Never tried uv coating aluminum. The production clear is made for better adhesion on difficult substrates like coroplast. If you don't mind me asking, where do you get your uv coating from?

Were these samples you posted printed in uni-directional? Set up your colors as pms colors if not already. Some RIP softwares adjust cmyk colors. They read pms colors as spot colors and leave the cmyk values alone.

I've seen this several times on our QS2000 when ripping a file in a different resolution than the printer is equipped to print with. For instance if I print a 10 inch by 10 inch square ripped at 360 x 360 dpi and then print the file on our printer which prints at 540 x 360 dpi the result would...

Oh but ours is a solvent sorry. Vutek probably has a uv equivalent.

We run a vutek 3360. Part of the platen is removable exposing a trough directly beneath the print area. Works great for mesh.
