Service and technical manuals

Duplicators typically come with a User's Guide for the model—which go over basic operational tasks that most users should know. For many Risograph machines, there is also a Technical/Service Manual that goes more in depth into fixing issues, solving problems, and adjusting various settings not available from the regular interface or simple adjustment dials and levers.

Some service manuals are available for download from archive sources:

Individual manuals should probably be moved to features on the relevant Category:Duplicator series pages—but redundancy with this page is good. Though perhaps it can be generalized to something like "Technical documentation" and encompass parts manuals and technical bulletins too.
