We dont have the same one as you but on ours there is a screw on the bottom piece that adjusts the bottom die up and down for different size materials. If yours wont adjust you could always add small squares of vinyl banner material to the back of your banner where the grommet goes to thicken...

You need to be careful pushing acetone through the head with a syringe. That should be a last resort option only. I agree with you though. If you have a vacuum then something is clogged. I would clean off the black captop and the wiper. Run a cleaning cycle and see if any new black ink has...

Looks like a heat issue to me. Touch the left side of the platen with the heaters on. Does it feel as warm as the right side? Does it do this in all pass modes? To me it looks like the heat is too low causing the ink to pool up on the left side of the machine. You might just try running a higher...

I'm not too familiar with the dx-5 so correct me if I'm wrong. You need to determine if its an electrical or ink delivery related issue. For instance, when you run a cleaning cycle the jets dont actually fire. The pumps pull ink through them. So say if you put cyan cartridges in the magenta...

We have a bu-1600rfzy. It works great as far as I'm concerned. Simple and easy to use.

I will have to try the dryer sheets. Do you still have the boards? Maybe you could send them in to get repaired to one of those circuit board repair companies. Its possible if they find out whats wrong with the board than you could attempt to determine the cause.

I dont know much about the CET printers specifically or why you have replaced the head boards so many times. As for the dropouts and negative pressures can you adjust the negative air pressure via a precision air regulator? Does your machine have one? Static sucks. I assume youre cleaning the...

Hmm.. and what about torque pressure and weld pressure? Just curious as I have found very few people to talk to about welding. We have a t-83 air. We also have a t-100 wedge for the hems. Do you know any resolution for welding against the biased edge short of running heavier material? I work for...

You say the vertical bands are inline with the rollers? Are you referring to pinch rollers?

I have never welded that material in particular but in my experience smooth banner material is harder to weld than scrim. Its just hard to get a solid weld without a little heat distortion. What kind of welder are you using?

We have a 10 foot table that we keep in front of the laminator for short runs. We just bump the table until its flush with the laminator and then use the 10 foot side to square our material up to the laminator. It also helps for mounting decals onto rigid substrates.

I dont believe the ouput will help as much as the timing of your lamps. What are the options you have for shutter or curing settings? The post I was talking about I believe heats the material prior to laying down the ink. This would affect dot gain a little bit similar to a solvent printer with...

If its the actual gamut range that bothers you then you might try looking into different rip softwares. We use fiery and yellow has always been an issue. Damn program adds magenta and cyan to process yellow. But our colorburst rip doesnt. Your lamps can affect the pop of the color as well. Our...

We have a vutek. Running the lamps on post curing helps a little with color and ripping files with rendering intent set to absolute colimetric helps a little too. The colors are still disappointing though compared to solvent.

Try slowing down or speeding up the carraige speed if possible.

Vinyl gloves and sometimes protective eyeware if spraying the chemicals on. And clean those uv screens good. That ink can be very messy since it doesnt dry.

Is it possible that you have a glare from the light hitting the encoder strip? Just a shot in the dark. The lights from your room.

I did some research before deciding to respond again. Because the ribbon is for the whole head doing a data swap is not possible. It doesn't look like there is a way to test the head ribbon short of replacing it. Somebody on this site may know a way but a lot of them do'nt respond on weekends...

To me it sounds like ink starvation or air in the lines. If it was electrical you would have lost all of the nozzles or exactly half if the mutoh heads had two sets of jets in them. I don't know anything specific to mutoh printers so thats all I got.

Looks screen printed. White borders are very common in screen printing. Maybe thats a thin styrene .020 or .040. Most sign shops could duplicate that fairly well either by screen printing/flatbed direct printing or printing decals and mounting them.
