Contemporary ink tubes (used from the onwards) use an RFID sticker on the end of the tube to record basic ink information (color, type, volume remaining, expiration date, etc.). Each drum holds matching values so that it can recognize the tube—and notify the operator if the wrong tube is inserted in the drum.

However, there's many situations in which you might need to reprogram a drum to recognize a different ink tube (for example when transitioning a drum)—this tutorial walks through some different procedures and values you may need to reference.

Drum reprogramming

Drums can be reprogrammed in two ways:

1. Automatically, using the ink code copy function in test mode.
2. Manually, by changing the drum's color values by hand.

Ink code copy

Test mode 890 performs the "print drum ink code copy" function.

1. Turn the Riso on in test mode.
2. Install the drum you are reprogramming.
3. Remove the old ink tube and insert the ink tube you are trying to reprogram the drum to accept.
4. The Riso will throw a D04-534 error, which you can clear by pressing the RESET key.
5. Run test mode 890 (punch in 890 and hit START).
6. Turn off the Riso and turn it back on in test mode.
7. If no error appears, the drum was successfully reprogrammed—if the error persists, you may need to use the manual method below.
8. Optionally you can change the display name for the drum (see instructions at the end of this article).

Manual reprogramming

Drums store two values to recognize the ink tube and a third which labels the drum (all three of these are copied from information on the ink tube RFID sticker when using the "ink code copy" function).

Test mode	Name	Description
1214	Ink color code	A numeric code representing the ink color (standard colors have unique codes, while custom colors often share codes).
1215	Ink category	Toggles between "Normal" (1) and "HD" (2) or "HG" (3) for specialty black inks.
951	Drum label	Adjusts the displayed color label for the drum (i.e. "Red 3," "Yellow 2," etc.)—this is displayed on touch-screen machines and used when selecting the drum to be used in from the print driver.

The first two values are in the protected area of the test modes, and must first be unlocked with test mode 9874.
