Hey Jim. This normally happens only with the PK channel on this model, but it can happen with any ink channel theoretically.
The problem is there is a perforation of the film in the damper of your Yellow channel. The damper is what connects the ink line to the print-head (it does a lot of things such as filtering, pressure regulation, etc). If this damper has a leak, the yellow can simply fall into the waste pad of the printer and empty your cartridge.
In short, the printer needs to get checked out and will most likely need a new “ink supply unit” which is the whole assembly from where the ink carts go in to the ink lines to the dampers (all connected).
This unit is about $160 and is available at compassmicro.com but it is a rather involved repair if one is doing it DIY . . .
