Troubleshooting Riso Error A16-525: The "Phantom Master" Fix If you are using a refilled cartridge: Check

If you are seeing Error A16-525 on your Risograph (common on EZ, RZ, and SF series), your machine is likely stuck in a loop. The official meaning is: "Waiting for the master to be removed from the print cylinder (drum)".

Essentially, the machine thinks there is still a used master wrapped around the drum and won't let you create a new one until it’s gone. But what do you do when the drum is clearly empty? Here is how to diagnose and fix it. 1. The "Quick Reset" (Try This First)

Sometimes the machine just needs a nudge to realize the drum is clear.

Manual Removal: Pull the drum out and double-check the "clamp" area (the long silver bar that holds the master). If a tiny scrap of master paper is stuck under the clamp or near the sensors, it will trigger the error.

Power Cycle: Turn the machine off, remove the master disposal box, wait 10 seconds, and turn it back on. 2. Check the "Light Absorber Strip"

This is the most common cause for a "false" A16-525 error, especially if you recently replaced your drum screen.

How it works: The Riso shines a light at a small black velvet strip on the drum. Troubleshooting Steps To resolve the RISO Error A16-525,

Reflection = Master Present: Light reflects off the white master paper.

No Reflection = Drum Empty: Light is absorbed by the black velvet.

The Fix: If the velvet is dusty, worn, or scrunched up, the sensor sees a reflection from the metal/mesh underneath and thinks a master is present.

Clean it: Wipe the black strip with a dry, lint-free cloth to remove paper dust.

The "Sharpie" Trick: If the strip is faded, many users have success carefully coloring it with a black permanent marker or covering it with a small piece of black matte paper tape (like gaffer tape) to ensure it absorbs the sensor's light.

Before you panic and order expensive replacement parts, understand that this error is usually caused by three distinct issues. You must diagnose in the correct order.

Less common, but more severe. If the PF (Paper Feed) motor is failing to maintain constant speed, or if the wiring harness to the register sensor has a micro-fracture, intermittent timing errors will occur.
