I was looking at the Seiko Dryer and it looks to be a pretty good setup and design, but I noticed their was an attachment that installed on the rear side of the printer it has a large curveature to it. Is there any place that we can purchase that attachment seperately with the hardware without buying the dryer?
depends what you want this for. in my experience this is supposed to push the substrate nearer the heater to aid drying. in practice this make a negligible effect on the overall drying time on any substrate.
We were running the Seiko dryer but could not get our prints to dry in enough time before they rolled up, then they would all get stuck together and when u unrolled the roll, the prints were all stuck an you had to peel them apart which would destroy the prints. We use infrared digi-dryers and they seem to work very well with the additional seiko part that was on the machine but we had to give all the equipment back so now we dont have it anymore. I was hoping we could obtain that part again so we can run at a faster print speed again without destroying our prints. Seiko says you cant buy it seperate but that makes no sense to me because what if that part gets dented or the hardware breaks. . .
don't really understand why you couldn't dry your prints with the dryer. by using the correct media profiles and even at 16sqm/hr our prints were bone dry. remember it's not the heat that does the majority of the drying it's the airflow. try increrasing the flow across the substrate with fans or the like and combined with your heat it might do the trick, without manufacturing the extra guide.
All the profiles we use whether or not it was an Avery, 3M, Sihl, Solvex, Magik were exactly for that media from the manufacturer. Dont get me wrong, if it worked we would have kept it. Maybe we are laying down too much ink? How can this be calibrated? If you look at the prints comming from our CP64s compared to our other machines, this one looks wet like like a car after it was just waxed and now it rained on it. The prints looked outstanding if they were just being fed onto the floor (this was of course before our newly established banding issue) Any help is greatly appreciated it. Im going to get this machine to work and take it 1 problem at a time with or without the help of Seiko.
sounds really weird. normally i've only seen this effect if a) the wrong profile has been used, b) if you print on the wrong side, or c) the coating reacts in some way.
have you tried slowing the printer down, or varying the heat temps? does this happen on all substrates, being sav, banner, paper etc?
We have adjusted heater temps in 2 degree increments, and yes the drying problems are usually only a problem with the vinyls even the matte vinyls so its not just the semi gloss ones and high gloss. What really interests me is the fact that it isnt limited to just our one supplier. Its on all of our vinyls whether its Avery MPI1005EZ or our 3M IJ180. It does not want to dry in time before we roll it up. I just dont know what the problem could be. The only thing i can even think of is that this machine is calibrated incorrectly and is laying down too much ink which in turn leaves it an insufficient amount of drying time before it hits the wind up device.
essentially the priner is a dumb device so it's only laying down what it's told to do. if this is the case then it's back to the rip/profiles/settings to rectify this. have seiko got involved in this problem?
Seiko has been about 1000% useless getting my problems solved. I have to follow up with them 5x a day just to get a return phone call about a phone call i never received. They were supposed to escalate our issues past GEI Calgraph 2 weeks ago but that never happened.
Sorry to hear of your drying issues. Sometimes I use one of those Black Box external heaters when printing 4-pass on some non-matte vinyl. I hardly ever use the extra dryer though since I mostly print on matte substrates.
