If the error persists after the above steps, the issue is likely mechanical or electrical.
: The black fuzzy strip on the drum (light absorber) is scrunched, missing, or damaged, causing the sensor to fail. Screen Issues
If the error persists even after you've removed the master, the machine’s is likely misreading the drum surface. 1. Darken the Light-Absorbing Strip riso error a16-525
The RISO detects a master by bouncing light off the drum. If it sees a reflection, it thinks a (white/light) master is present; if the light is absorbed by the next to the clamp, it thinks the drum is empty.
To prevent the Riso error A16-525 from occurring in the future, follow these best practices: If the error persists after the above steps,
The typically occurs on EZ, RZ, and SF series machines. It indicates that the machine is "awaiting for the master to be removed from the drum" . Essentially, the printer believes a used master is still attached to the print cylinder and must be cleared before a new one can be created. Quick Fix (Manual Removal) Open the front cover and pull out the print drum.
Turn the machine off. Hold the Left and Right Print Position buttons (or similar keys depending on the model) and turn the power back on. Run Simulation 117: This resets parameters to default. To prevent the Riso error A16-525 from occurring
Use a black Sharpie to darken the velvet strip or apply a small piece of black gaffers tape or electrical tape over the area where the sensor looks. 2. Clean the Master Sensor
Ink mist or dust can cloud the sensor, causing it to "see" a master where there is none.
This solves over 50% of A16-525 errors.
