yellow head only firing half
I am printing using a sol jet pro 2 V. I initially had a problem printing gold as it was coming out brown. I discovered upon conducting a test print that only half on the yellow head is firing. The right hand side of the head is perfect but absolutely nothing is showing on the left hand side. I have gone through the usual cleaning, cleaned the tubes and the capping station. I can see the ink is sitting in the damper and the tubes are full so no issue with coming from the cartridge.
Last Night:
I switched the dampers that feed the left and right nozzles to see if possibly one of them was not working but now there is no yellow coming through. So from that I can only think it is a blockage in the head? -

We recently had awful trouble with our magenta head doing this.
Problem was the drain tube was clogged up and was filling with waste ink and blocking the head.
Have you tried soaking the head? You will likely need the tool to manually lower the capping station (although i have no experience of sol jets). Ours was around £10 from Roland, for an XC-540
Turn power off and then clamp off the drain tube (I used small bulldog clips) and then fill the capping station with cleaning fluid using a syringe, raise the capping station and leave the head to soak overnight.
In the morning remove the clamp, turn the machine on and run a cleaning cycle, followed by a test print, it may take a few cleaning/test print cycles to fully clear the head.
Repeat as necessary. Any stubborn blocked nozzles can usually be cleared by slowly pulling ink through the head using a syringe on the end of the drain tube.
This worked for us, if your machine falls apart then explodes..not my fault :lol1:

Cheers for the advice. Done the last bit you advised. Once heads were at the capping station I detached the yellow drain tube and pulled the ink through. Done a powerful head clean and hey presto all nozzles firing.

Glad to hear it.
Do you know why it happened though as it will likely happen again if you don’t fix the cause.
Make sure your capping station is making a good seal as any small air leak will dry nozzles up in no time.
Also make sure the drain tube has no blockage, I could feel lumps in ours from dry ink that i had to soften up with cleaning fluid then pull through, it was all a bit gory since it was magenta!
