Our Kiosk 2 starts up fine
Performs a good head cleaning
Once I try to send a nozzle check from the computer I get a fatal error.

I have replaced the motherboard (switched the EPROM was originally told this was the issue but I really dont think it was) this is why I want to have some opinions before I send parts in and hire someone to come out.
Replaced - Carriage, ribbon cable, capping station, wiper assembly, head.

Youtube video can be found here

Kiosk FATAL ERROR PROBLEM
1 - 20 of 20 Posts
Yes. *changed the encoder strip, and I tried 2 another one just to be sure that one wasnt faulty.
Try checking after the board is loaded
press load button let it find home then try a nozzle check
the sensors are very touchy some thing may be telling the machine some thing is in the way
Ok I am going to try that now. Last night I hit load right after I sent a nozzle check and it printed the nozzle check, but after it was done printing it could not find home again. hmmm
If I load the tray before sending info it doesnt find home either. It goes back to the fatal error. Heres another video of what happens when I load it after sending a nozzle check before it fatal error's it allows it to go through the print motion, and then error's out. Any ideas?

Send Video- Prints if loaded before error
A side note...I understand electronics perfectly fine. I am however new to DTG and this machine. If you can help and happen to have the parts that make sense to purchase I will do so, however, I will not just buy a part because you send me a message and say thats whats wrong with it so id appreciate legit help. Thanks

Have you ever taken the encoder strip out ?

they do have to be installed in the correct orientation
just throwing that one out there
I found with my dtg it was usually a simple thing that would throw me for a loop
Did you remove the paper sensor from the carriage? I didn't realize that had also been replaced.
Yes paper sensor has been removed. Encoder strip in the correct position, new spring and encoder strips.
I have seen this issue before and it is a main board problem. I know you mentioned you replaced the board but seems there can still be an issue with it some how. Double check the connections as well as the EPROM. Make sure your printer is unplugged when doing this.
You said you replaced the EPROM. Did you replace it with one from a standard 2200 printer or from a Kiosk?

From the kiosk. Is it possible it could be what I've seen called the jumper board or the WIMS?
When you say main board problem can you be more specific. I doubt it is the EPROM due to the fact that the tray loads properly and if you load before the error it actually prints a nozzle check with correct placement.
Check the connections. It's hard to say specifically what the issue is on the board. Usually when your swapping boards and EPROMs around a component can get fried if something is not attached properly. What does your current EPROM look like? Is it flat and black or is it blue with spikes on it?
Flat and black
I was curious. That is an old one. I'm going to take an educational guess on this one from my experience and what I have seen in your videos. I'm guessing that your printer is no longer acting like a dtg printer but acting like an Epson 2200. Since you don't have the sensor attached to the bottom of the carriage anymore your printer is going into error at home base. As you may know the EPROMs get flash with a coding to work properly as a dtg printer. What I think happens is that when your swap eproms around the coding may get deleted, reset, or damaged causing it to act just like an Epson again. I'm pretty confident on this guess. Replacing the board with a working one that has been properly flashed may be the answer. But finding one may be hard.
My HM1 does something similar to this sometimes when I've unlocked the head and not set it back correctly afterward. Use the screwdriver to unlock the head and move it to the middle. Turn the screwdriver counterclockwise 2 turns until the capping station and wiper no longer move. Turn clockwise 1.5 turns until it's set where the head will move back on, just before the extra bit of turn to lock it. Turn on the machine with the print carriage in the middle and let it move back and reset itself on its own. This is assuming that the # of turns on my HM1 are the same as your Kiosk 2, but it might work. My machine only does this once in a blue moon, and it really freaks me out until I remember to try this first. It's worth the price of free to check it out.

The print head doesn't lock on the kiosk 2. The kiosk 2 has an Epson 2200 engine that is built differently then the HM1 that you have.
hi i have the same problem with my kiosk. did you find a solution for the problem ??
