Guide Media Vertical

The Lexmark 40X7586 media vertical guide is a printer paper-path service part. Lexmark identifies it as an MS81x service guide, and the MX71x/MX81x MFP parts catalog lists the same part number and name.

In the catalog, it belongs to the paper path assembly, with one unit per machine and one per FRU. A removal procedure is provided for this guide, supporting its identification as a replaceable service component for the listed printer family.
