It seems I have similar issue here. Would anyone advise me with my problem? I replied on another thread:

Hi,

This is my setup for normal Epson L1800. I've put the lamp on the left side of carriage unit and the height identical to printhead. I have problem the UV light would not cure the printed area on the right as when printing it seems the lamp aren't reaching to the right area, except when head pruning. How to solve this issue to make the print head travel a bit further on the right for UV lamp to have the chance curing artwork on the right.

P.S: I move the artwork to the left and put a small line at the right but it wasted so much paper and area as well not practical at all.

This is the ink is not cure the right area.

This is the printing and the UV light does not reach the right area.

You would need to find out the spec of the unit for if it needs an no or nc sensor and what voltage it operates with.

I would expect it to be using dc.

Hi Reptilesink,

This is its spec.

It seem to use DC. I'll check whether it needs NO or NC sensor more. Thank you!

Hi Uhim, Thanks for your input!

I just know that much! I wanna attach proximity sensor like this:

So, do I just need to connect like Blue + Black & Brown + Red as normal or I need additional stuff(s) to make it works?

Thank you!

Hi Andy!

What proximity sensor should I use?

- AC-NC Proximity Sensor 2-wire

- DC-NC Proximity Sensor 2-wire

Do I need to use relay to connect the sensor to the system's signal wire (black & red)?

Thank you!

Hi,

How would I wire this system to work with proximity sensor?

As a noob at this I've searched around for a while but I seem no clue about this.

Thanks in advanced!
