Reason Details:
Annual preventive maintenance visit for the Zeiss LSM 880 / Axio Observer 7. The visit was triggered by the routine vendor PM schedule and included follow-up on reported stage movement irregularities and reduced argon laser performance.
Annual preventive maintenance visit for the Zeiss LSM 880 / Axio Observer 7. The visit was triggered by the routine vendor PM schedule and included follow-up on reported stage movement irregularities and reduced argon laser performance.
Action Details:
Vendor preventive maintenance was performed according to the Zeiss protocol. Checks passed for environment, cabling, system startup, anti-vibration table, air filters, surge protectors, ECU voltages, electrical and laser safety, PC ventilation, microscope general function, liquid-cooling related items, detector/calibration routines, beam profile, AOTF, scan field, pinhole/MBS, and Airyscan alignment. MBS filter wheel axles were cleaned and lubricated. Maincontroller battery was checked at 3.03 V and not replaced. Manual stage control and tile-scan test were completed, but stage motion was reported as occasionally not smooth. The argon laser output was low and the engineer documented it as end of life, so some maintenance tasks including the SNR test could not be completed and were deferred until after argon laser replacement.

Additional Notes
Timeline anchored to the field service report completion date (2025-04-02). The signed maintenance checklist header shows 2025-03-24, so the repository timestamp was normalized to 2025-04-02T12:00:00Z because the source documents do not provide an authoritative visit start time. Final remarks state that the instrument is not fully operational: argon lines 488/514 are low and out of spec, and the stage may have a mechanical issue. Additional documented context: ZEN 2.3 SP1 FP3 HF 29 FP3, CanCheck 13.0.19.1, RT PC MICO HS, user PC RAM 192 GB, Windows 7 64-bit. Recommended follow-up: Replace the argon laser, then repeat the pending maintenance tasks and detector SNR test. Review stage mechanics with PI and decide between service/maintenance by PI or replacement with a new stage.

status_notes: Usable, but limited by end-of-life argon output and occasional stage
movement hiccups.
