RISO速印机的错误代码A16-525虽然看起来复杂，但其核心是围绕“滚筒版纸移除”这一动作的检测失败。通过本文的系统性排查，从最简单的重启、手动清洁滚筒开始，一步步深入到检查传感器和电机，大多数情况下的问题都能得到有效解决。
Sometimes the sensor "remembers" the error even after the master is gone.
Mastering the Riso Error A16-525: Causes, Fixes, and Prevention
Locate the master detection sensor inside the internal drum cavity (typically positioned on the ceiling or side wall where it aligns with the drum's clamp area).
Underneath the master sheet on the drum cylinder lies a dark, textured area known as the . The optical sensor shines light on this area; if it sees a reflection, it assumes a master is present. If it sees pure absorption (darkness), it knows the drum is empty. If this strip is scrunched up, peeling, or covered in reflective ink, the sensor will throw the A16-525 error even on a naked drum. 4. Recent Screen Replacement Issues riso error a16-525
: Keep an eye on toner or ink levels and refill or replace them before they run out completely. Low levels can lead to print quality issues and errors.
This guide explores why this error occurs and provides a comprehensive troubleshooting framework to get your Risograph back online. 1. What Triggers Error A16-525?
At this stage, it is most cost-effective to contact your local Riso service technician to replace the faulty sensor or board.
: If the strip is peeling or scrunched up, smooth it back down. If it is permanently damaged, you can buy a replacement light absorber strip online via platforms like eBay. The optical sensor shines light on this area;

If you have more details about the machine model or additional context about when the error occurs (e.g., during a specific operation), I might be able to provide more targeted advice.
Locate the optical sensor area near the master clamp on the drum.
If you are using a refilled cartridge:
Commonly, adjusting the drum sensor position (e.g., to 100 or -100) or resetting the test mode to default (Simulation 117) can resolve persistent errors.
