Screen Printer Help - 100MV UP100 or Quad 100MV | 6 February, 2021

Hello,

I'm new to this forum. I recently purchased a 100MV Screen printer and unfortunately; it arrived damaged. I was able to turn the unit on and I was able to get the unit do the initiation process (ex. datums).

When I tried to do a sample PRINT operation; then a vacuum menu window showed and immediately the LCD became non-responsive. I restarted the unit and still non responsive.

I tried removing the IC of the LCD and the main board and re-installing it; and still no response.

Any help will be appreciated.

These machines are known for this. Keep reseating the chip on the display board. The mylar display looks pretty bad and may need replaced.

I spend several hours resetting both chips and no luck.

I have a question: The lcd not displaying could be the main controller board?

Does anyone sell parts for this machine ?

Make sure the pins on the chip on the main display are not bent or tarnished...i have scraped the bottom of the legs before.

I would try Reprint in UK. I think they still have parts.

Do you recommend soldering the chip to the available smd surface pad?

Did you mean https://www.sigmaprint.co.uk/?

Thanks

I would not because it could be the mylar that has an issue.

The mylar is just the keyboard and has its own connector. All the keys seems to work well (the lcd pcb has some leds and they blink when I push each key). The lcd is soldered on the display board.

For some reason i remember reseating the mylar and it working but it was probably just lucky and fixed a bad connection somewhere else on the board. I know we also reseated the ribbon cable.

Honestly speaking, do you recommend fixing the printer? Is it very reliable?

I tried calling sigmaprint.co.uk but they did not answer. The have no working links in their site and they might be out of business?

I believe sigmaprint is out of business....but Reprint still has a working webpage so they should be able to help you. I like those printers but they are very old and the boards can cause intermittent problems.

Do you have any direct contact for reprint?

Is this their site ? https://www.reprintinternational.com/

That is the site. I do not have a direct contact but i probably know a few of the guys. I believe they used to work for smtech along time ago.

Great. I just send them an email; I appreciate your support.

Quick question: I found it odd that the printer seems to be working fine when I turn it on for the first time. But as soon as I push the two "PRINT" buttons, a window of VAC came up and the letters in the LCD had some sort of error/miss-characters. Could it be possible that maybe one of the motors is bad and something got smoked and is just not allowing the LCD to communicate with the main board?

I think in the machine configuration there is an option to use the vacuum or not. Its been a long time but i think you just just skip past the vac message if it pops up. Pust both left buttons at the same (under the display) time to get into the machine settings.

Hi, so I was able to turn the machine on for a few seconds. It looks like the IC on the LCD doesn't have goo contact because it's very hard to keep the machine operational. I was able to see the table lifting for the first time; it was so cool! but then it stopped working again...

I have a few questions:

1. I noticed that there is a resistor close to the IC and it gets very hot to the point you can't touch it. Is this normal? I noticed is connected parallel to the power of the LCD screen so I figure it was normal.

2. Can you share a picture of your limit switches for the head? It will go back half way and then it will crash in the front and go to the main menu screen. Is this normal?

I was in the maintenance menu, and I tried to move the head towards the front or back and it crashed really bad.

3. I attached a screen capture of how the LCD looks when I try to do a quick print calibration.

Thanks for your help!

1. The resistor is normally hot. 2. If the machine is crashing towards the front then the system settings need reset. Do this by pressing and releasing the e stop then pressing both front left buttons on the mylar below the lcd screen. Go into the machine configuration and reset system parameters....after it homes you will have to reteach the front and rear limits and the squeegie blade postions for printing.

Thanks! Do you happen to have copy of the manuals? or any documentation at all to do what you just explained for doing the system reset.

Contact George at PPM in New Hampshire. He knows these machines very well and usually has any parts for way less than SigmaPrint

Thanks a lot! I sent the boards to REPRINT in UK, and I'm waiting to get them deliver to do the final testing.

Are these printers very reliable? I heard that if you have the stencil cleaner (my has) to avoid using it since it was a bad design and burns the power board.

We used to have 5 of these in service and they worked great. Only 1 had the stencil wiper, and we did not utilize it. We've since installed all inline printers, but we do keep 1 MV100 on the floor as a back up. The firmware can get squirrely and the ICs often need to be re-seated to clear up issues. When the touch pen and vision system start to go, parts are very rare. Sometimes the machine will just sort of lock up and not want to do anything, but 9 times out of ten, we go in and set parameters to default and it clears right up.

Thats good to hear. I have (1) extra boards for the LCD and the Motion drivers in case something gets damaged later because as you mentioned; parts are very difficult to find (or super expensive)

I did soldered the IC chip on the LCD unit and get REPRINT to inspect it and it seems to work...will see.

Yep. I kept a lot of the parts from the ones we took out of service just to keep the last one running.

If you ever have the acrylic LCD part with keypad and willing to sell it let me know.
