Welch Allyn/Hillrom-6570-842-02-Platen Shaft for ELI 380
Part #6570-842-02 is the platen / shaft component used in the ELI 380 resting electrocardiograph in its U.S. version. A platen in this context refers to the drum or plate over which the thermal paper is guided in the printing / writing mechanism (thermal writer) of the ECG machine. It helps ensure smooth, accurate movement of the paper across the print head, maintaining correct alignment and tension so that ECG waveforms and diagnostic information print cleanly and without distortion. The platen is mounted inside the paper tray/writer assembly and works together with associated gears, bearings, spacers, rollers, and sensors as part of the ECG device’s paper feeding / printing mechanism.
