Designjet T770/T790/T1300/T2300 Ink Supply Station | Q6683-60188
System Error: 22.0:YZ
You are having issues with the left ink supply station. One thing you can try is to remove all ink cartridges from the left side and turn on the plotter and see if it gets to where it asks for the supplies and then you install one at a time. If that does not work, replace the ISS.
