Seems like the XR-640 cost about 16k new some years ago. Hard to justify putting that much into it. That said, we had a bad head strike a little over 4 years ago and replaced the heads. Machine is running great still. Head strike is caused by material tunneling as it feeds - often unequal wear...

One thought this morning: remeber the angle you pull the vinyl up at impacts its ability to come off in one piece and with the adhesive (to some degree). Try pulling at 45 and 90 degrees, usually 135 degrees and 180 degrees are both too much. Scrapers and Lil Chiseler are to start the vinyl, not...

Wall-paper steamer... dangerous to use heat (though sun will warm it up for you), but when you need heat on any fuel vehicle a wall-paper steamer is the way to go. Lil Chiseler scrappers help. We also have 4" Plastic Safety Scrapers (Item SRWGPO) we got off of Amazon. Some Rapid Remover to get...

Orajet 3981 RapidAir Premium Digital Eco Print Film and then there is Oraguard 289F PVC-Free Laminate to put on it. Not cheap, but 10year outdoor life and suitable for wraps. You can read a bit of it on Grimco's site, though they are out of stock right now...

We have some very OLD ones still here. Can't promise yours is the same size, but ours takes a 39.5x95.75 panel and the channel accommodates a .75" panel.

I am not familiar with this brand, but looks like what you get when your flatbed printer negative pressure needs adjustment. Sometimes an air bubble can do something similar, but consistency points to negative pressure (the negative pressure setting holds the ink in the head until printing, too...

Read the directions... used to be with Liquid Nails, you put the adhesive on one side, lay on the substrate, pull back off and wait 10 seconds (or so) and then put it back on for a better bond.

Liquid Nails Fuze It All Surface would be what I would try now. I think what we used to use was Liquid Nails Extreme Heavy Duty

On big stuff, we used to use Liquid Nails. Care must be taken to spread it evenly on you see slight ripples in the aluminum. Now we hardly ever need do that - instead we buy Aluminum composite (ACM), which happens to come in brushed aluminum finish as one of the colors.

Haven't used 201HTAP, but can say 3M SCPS-55 or R-Tape 4075 Conform RLA do not stick real well to GF 226HTR and MacTac Rebel 228H. They will work, but you have to remove the wax liner from the masked vinyl, not the vinyl from the waxed liner. Might try 4076 Conform RLA Higher Tack or 4885 Super...

We just got some parts from them last week. They are in Illinois, so time difference for us. Phone number is 800 232 8018 if you want to compare with number you are using. I haven't had too much problem reaching after noon East Coast time.

As far as materials: 1. Acrylic for 4x4, polycarbonate for large faces. Polycarbonate needs to be off-gassed for 24-48 hours before applying vinyl to the faces - that means pulling the masking off 24-48 hours before lettering. 2. Translucent vinyl would be appropriate, and was designed for this...

I should add a few things: If you get prints that look like static on an old TV, that is usually an indicator of Negative Pressure being off. Air does sometimes get in the lines, Air bubbles can cause overspray and will cause streaks of off color. We clean coroplast off with Solv S1000...

First thing I would ask is if you have a breeze running through or a fan on while the machine is running. That can blow the droplets off course. Second thing I would check is negative pressure. Ever drink a soda from a straw - every play with it? Think of the holes in the printheads as straws...

The R98H has Ricoh Gen 5 heads

Check your cables. restart the computer that has the Production Manager on it. If that does not work, you can try to reinstall the plotter (maybe give it a new name). When we have had a similar issue, it is nearly always the cord, and when it is not then a restart has worked.

You can use Oraguard 290 on 3551. But agree with Solventinkjet regarding his tips about the blade.

2-3% would be typical. As high as 5% is not out of the question for certain jobs. Normal Finder's Fee is 2-5%. But the question becomes whether you pay this person just once or if you pay him everytime the new business uses you from now till forever... That would shape the percentage in my mind.

Your monitor and your printer will always have different color ranges - the monitor more plus it is more vibrant since it is light. Your RIP will also impact the color output. For instance, we have a Roland printer and use Versa Works with it. We also have Oynx for a UV flatbed printer, but can...
