Maintenance toolkit: Difference between revisions

Revision as of 18:49, 23 November 2025

A toolkit of a few key items will allow most standards repairs on all models of risograph.

The majority of these can be found in any hardware store, but a few will likely need to be special ordered.

Item	Notes	Product
JIS Phillips #2 screwdriver	The screws in a risograph conform to the Japanese Industrial Standard (JIS), not ANSI (used in the US), or ISO (used in Europe).^[1] Using a proper JIS screwdriver will provide more torque to stuck screws, and make it less likely that screws become stripped.	[1]
Metric hex keys	These should be separate L-shaped wrenches, not part of a pocketknife-style connected. The sizes needed (in millimeters) are: 5, 4, 3, 2.5, 2, 1.5.
