RISO

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.

Please note: I am not a certified Riso tech. This method has worked for me through trial and error and reading through the technical manuals. Find a clean work space and lay down some kraft/butcher paper because it will be messy!

Ink color code chart from the Technical Manual

Here's a list of color codes for the RP series (should work on all models, have been tested on a RP3100UI and RP3700).

Unlike with newer machines which use chips to show the appropriate color on the Riso, the ink must be manually dialed in on the RPs through a Test Mode setting. It is however not necessary to change the color code on the drum after swapping ink colors but if you want the Riso to show the corresponding drum color on the display, you can use the codes to update the drum settings after changing inks.
