I am trying to get an older Agilent 6890 with 6890 Series Injector autosampler and Controller up and running in our lab. Afer a couple of successful trial runs, I started getting an error message "Front plunger error." I have cleaned everything I can in the turret, replaced the syringe, and even tried running without the syringe installed, and still I get the error message.
The plunger carrier loop seems to slide pretty freely, but there is a plastic gray lever near the top that looks like it should move, but isn't doing anything (sorry I don't have the proper name for it, my manual is sorely lacking information!). Sometimes the autosampler will get started, try a couple washes, and get to the sample and then have the error--other times the error shows up on the first wash.
By the way, my "solvents" and "samples" are just empty vials at the moment while I try to get this thing working. No one in the lab knows if the autosampler has ever even been used (or they're not admitting to it!).
Thanks for any suggestions!
