How to: clean an MZ/EZ/RZ drum to change colors

You can help by rewriting the linked articles into wiki format for this page (preserving them as sources using <ref>...</ref> tags) and then removing this message. Migration notes may be available on the wiki roadmap.

There are many reasons a drum may need to be opened—to repair an issue, clean out old ink, transition to a new color, etc. This article outlines the common processes in disassembly, testing/cleaning, and reassembly, but does not outline specific maintenance (i.e. correcting the squeegee gap, etc.)—those are separated out into their own tutorials.

The golden rule of drum repair is: only go as far as necessary, and no further. Drum repair is inherently dangerous to the riso. Misassembling a drum and trying to print with it can result in totalling the drum and damaging the riso itself; many of the individual components in the drum are quite delicate; the process is arduous. So doing as little as possible on drums is a good way of limiting the potential for error.

 <!--This tutorial applies to MZ/EZ/RZ drums. The purpose of this tutorial is to clean and prep a drum to change the color. This tutorial simply shows taking apart and cleaning the drum for new ink. Cleaning the drum instead of trying to flush out the old color with new ink will save you a lot of ink and paper.
