After a used G4513A sampler is installed on a new 8860 GC-5977C instrument, the injector couldn't finish injection process in sample run and it will do the routine but in the step of the injection the needle will stuck a little above the port and gave an error code 201 in the end, syringe carriage error. Sample was not injected. The fault light flash twice indicating X-axis problem, however align function cannot achieve and stuck. Any one has idea what is going on here and how to solve it? Thank you very much.
