I have seen this before, sometimes the sensor or the flag that tells it the bag is present, gets out of position and the flag is just not breaking the sensor as it should, and it thinks there is no bag there. If you pull the top left and back cover on that side, it will expose the bags and...

The PIP is what controls the pressure to the PH. They usually throw errors, but I have seen them just be faulty with no errors. If ink is dropping out after starting good, then I would be looking at that for sure. I am not sure why the encoder was replaced, that has nothing to do with the ink...

Curious what the wheels have to do with ink fading? Look, I never use all of the wheels, they are not needed. Even on 18oz banner I use only 4 equally spread out. Vinyl just the 2 outside ones. If you are laminating and cutting, then I would also use 4 spaced as evenly as possible. Heat runs the...

Have you color calibrated lately? I would grab the Generic SAV profile clone it, be sure to put a check in the Long print box and rename it whatever and perform a color calibration and see if that resolves it. I normally set the first step on the saturation at 100% and lower the heat to 200...

What Firmware do you have on the machine? current version is for TR2 ink is 4.10 is the most current if you have 4.00 then upgrade the FW. It could just be coincidence and the chip can be bad. I have seen it before. If you have another bag stick it in there, just to see. If FW is current and...

It is a fully functioning Roland RS-640 VersaArt sign making machine. It is in very good shape. All of the heads are full and printing perfectly, low hours on the motors. It is fast and produces fantastic results on just about any roll media. Has a working heavy duty take up unit attached. If...

Sightline- I hate to say, but I have done this and it has fixed the problem with OPEN AIR bulk systems. If it alternates between carts, the ink lines are still being fed, no matter which cart or solenoid is open. So with that said, let me ask you a question because it appears you have some good...

Slightline You are correct, thats why I was asking. Those are called "S" dampers, and they will squirt ink all over you if you squeeze the spring So beware. I wanted him to look, obviously if they were less than full that could be pointing to a flow problem, (ie air being induced) Good...

Yea that 170 got my attention to!! Cant help ya without the answers to my questions.

If you want to reduce file size while not hurting your output... PDF is the way to go. JPG is a bad suggestion, it may work for you but you are the minority. Even though your using those high quality settings when saving, you are still compressing the file and that will cause issues down...

Well that must have just come out within the last day or two, I have not updated my Roland database since last Friday because I have been on an HP Flatbed install this week. Nevertheless, I doubt its FW, but its always good to update. My suggestion would be do ONE thing at a time, so you...

Signguy Although Arlon is not the best choice of medias, its still a decent material that will usually render a good result. Be mindful that media companies are not perfect they do run into issues when making media. I cant tell you how many times in life repairing machines, that I have...

The FB500/700 machines are great machines. I really enjoy installing and training on these machines. The accessories are cool having the ability to print white and then go back to 6 color after you complete all your white jobs and although they are a pain in the butt the roll to roll system is a...

Changing the head is fairly straight forward, its the adjustments and calibrations that are the difficult steps. I would highly recommend having an experience person do that. If you do something wrong, you can really cost yourself alot of money. Good Luck

Jim I am a bit confused by your question. Can you take a pic of the area you are referring to, maybe point at it?

May I ask why this Model? Just curious

How much ink is in the damper? Are you running a bulk ink system? You can try syringing through the cap. You have two lines coming from the cap going to the waste bottle. I would block off the right side line on the cap, and put a syringe on the left line and pull through it. Run a cleaning...

The ink delivery system on these printers really sucks with bulk ink systems. First I am going to say that open air systems cause problems, sooner or later you will experience ink delivery problems. Running actual cartridges will fix most ink delivery problems you are currently experiencing...

Is this a JV-33? What model printer do you have?

Arlon 6000 XRP is what he stated. Mudmedia: Beware that to much heat doesnt allow the ink to gain likes its design to. Which can cause color issues. I also understand that Humidity and Ambient Temp is a factor too, but I am just throwing that out there.
