Agilent 1260 HiP Sampler (G1367E) arm hitting left wall

Hi everyone,

   I'm currently experiencing an issue with the 1260 autosampler arm hitting the removable left wall of the autosampler chamber and erroring out (theta axis timeout). Currently, the system is able to pass the auto-alignment fine as well as start up diagnostics; however when the system tries to run a sample not on the far right sight of either a 100 vial plate or a 2x 54 vial plate, the arm slams into the removable left wall.  When the arm goes for the sample, everything is fine, it just seems that when the arm is moving to inject the sample, it rotates in a manner that makes me think the system thinks the wall is not there. The theta axis error is due to the arm wedging itself against the wall.  Does anyone have any advice on how to fix this issue?
