I've recently been getting some crashes on our QMDI Pro where it will come to a hault. During the crash, it resets my counter to a previous number, disengages 1-3 units and some blowers come on briefly. It's like it's going into a reset state. I've noticed in the past that resetting the plug on...

Hello. I am looking into some sort of perfing system that could work on the DI. We have been looking into Litho Perf a bit, but I would like some input from anyone who has some insight on this or has used any type of perfing product on the DI. Thanks!

Check out StudioRip. Our original Rip crapped out on us a few years ago and we took this route. Its performed absolutely amazing and it gives the ability to link up multiple presses with hot folders. One big plus for us on this was the simplicity of the recognition of spot colors in the file...

The sheet length does show correct on S43The sheet length does show correct on S43 now. Unfortunately I am not receiving any more powder from it. now. When I use S04, the powder comes out just fine. Does it just get a stronger blast when using the S04 opposed to when it's just on impression?

I found the sensor you were talking about. I forgot about that one. It was gummed up which is why it was giving me those large numbers, but it didn't fix the issue. With this unit, there is a line that goes into the dryer system to keep it cool and then the other line to the spray bar. The...

Is the sheet length sensor the same thing as the sheet travel monitor that you need to get too from the hatch on the catwalk? Im just wondering where to find it if it's a different sensor.

I checked it this morning and the top number is 607 and bottom number is 609. Those numbers seem odd to me as sheet lengths for these presses don't even go up that high.

Hello. Yes the special function for sheet travel monitor is on. I've tried just about everything that I can think of. Like I said, I get plenty of pulse from what I can see in the powder canister itself, but very little that come out of the spray bar. I just rebuilt the dryer and checked all...

I agree with mantman. The ink densities are probably too high and the ink is over saturated. We like to keep our coverage at a maximum of 240% if we can achieve that. If we are printing a rich black we use the formula C=40 M=30 Y=30 K=100. I'm sure you've already checked this, but make sure...

Hello, Thanks for your reply. This is a powder spray/dryer system. Here are some specs for it as well as an image of the cover of our manual. I believe the model number might be OP-DISIR Model # HBQMDI-2-27PF 200-240v

Hello. We have an Airtech quickdry powder/dryer system on our press. Recently we stopped receiving powder out of it. I rebuilt the dryer system and replaced the manifold in the spray system. All lines seem to be unclogged. When I use special function 04, i can turn the system off and on and...

I am in the works of replacing a couple of laser diodes on our QMDI Pro. I am more or less winged it the last couple of times, but now that I replacing a couple more, what is the correct number to use as the new identification number for diode? It looks like it accepts a 3 digit code, but I'm...

Hello. I went ahead and reset the rollers again yesterday and checked the packing and the blanket pressure. Everything seems to checkout fine. I tried backing off the 3rd form roller pressure and adjusted the pressure from the oscillator rollers to the form rollers. I had no success with...

Thanks for the help and explaining how it works. I do have a new set of veins and a new filter so I am going to go ahead and toss those in and see if that could clear the issue. It sounds like the air coming from the pressure release valve is just a clogged filter with a bunch of graphite in...

Hello and thanks for your response on this issue. 1. This was printed uncoated stock(70# husky uncoated) but I will get this issue whether is on 50# uncoated or 100# gloss cover. I have tried a higher tack yellow at one point. It didn't clear up the issue, but it did help it. I can usually...

On our QMDI Classic, we have been noticing a decrease in blast air on the feeder. I checked the vacuum pump and there was air coming out of the pressure release valve on the pump. I went ahead and pulled off the front plate and pulled out the two filters. The right filter is filled with a...

Hello all! So we are running a QMDI classic and Pro. On our pro, I have been getting toning/banding issues for a few months now on the #4 unit. It only takes less than 50 sheets for the toning to start. Sometimes it can be on the first sheets coming off. I have pulled all of the rollers...

Hello, I will pull the schematics and see what I can find. I am not an expert with electronics or troubleshooting anything to complicated with electronics. I will see what i can do though.

Hello, Chock Could this issue be anything within the pneumatics at all? There's the black pump under the catwalk (forget the name of it) that controls the airflow to the suckers and the feed head and it only shuts off when the press crashes while on impression. I've checked for air leaks and...

Hello! Thanks for the reply. You mentioned pressing Key S 56...is that a special function? This is for the pro which doesn't have the special functions. I just want to clarify that this isn't for the classic
