Procedure for converting the color of a Z-type drum. Steps 1 - 9 also work when machine does not recognize a correctly installed ink tube.

Steps

1/ Insert new ink tube

Turn the Riso on in Test Mode

Hold down the left and right position arrows for drum 1 while turning on the power. For ME machines, use first position drum arrows

2/ Enter 117

This tells it that it is a ledger size drum

2b/ Push “Start” x 2

3/ Push “Stop”

4/ Enter 890

This tells the Riso to recognize newly installed ink tube

5/ Push “Start” x 2

6/ Push “Stop”

7/ Press "Reset" to return to exit Test Mode

8/ Open the glass top lid and take a "sky shot"

A "sky shot" is simply a scan with nothing on it. Sometimes it helps to put a 1" - 2" strip of paper on the feed side of the scanner to help prevent the printed image from wrapping around the drum because of too much ink on the lead edge.

The ink colors will blend now. you can clean the drum, or deal w it!

Run as many copies as it takes to fully convert drum to the new color

Usually more than 500.
