3890 Digital Fiber Sensor retrofit
An alternate sensor solution, with a specifically designed transport retrofit, helps to substantially reduce sensor consumption, service related repairs, machine performance and downtime issues in this area of the 3890 for IBM Maintenance Agreement customers. In addition, this retrofit design can be tailored to other areas of the 3890 which have similar pneumatic sensor and contamination problems.
A commercially available Digital Fiber Sensor, made by SUNX Corp., is used and specifically tailored to the existing 3890 transport guides with uniquely designed attachment bracket assemblies for both the upper and lower portion of the machines transport. The brackets were designed and built by IBM to prevent the contamination issues described above. The IBM retrofit design, procedures, installation instructions, and service maintenance support documentation have also been developed to provide support for IBM Maintenance Agreement customers. This publication disclosure is specifically related to the bracket components design and methods for performing the retrofit of the 3890 using the commercially available Digital Fiber Sensor, made by SUNX Corp.
Examples of the brackets are attached below:
