If cleaning fails, more advanced solutions are required. Replacing the feed tires and separation pad is a standard, low-cost procedure that restores mechanical reliability. In cases where the error occurs only when printing on heavy stock (e.g., cardstock), adjusting the "paper thickness" dial or lever to a heavier setting changes the pressure between the feed roller and separation pad, allowing thicker media to pass. For persistent sensor errors after cleaning, a sensor test mode exists within the Riso’s service menu. Entering this mode (often via a specific key sequence) allows the user to wave a piece of paper in front of sensor 525 while the machine is idle; if the display does not change state, the sensor is electrically dead and requires replacement by a certified technician. Attempting to bypass or ignore the A16-525 code—by repeatedly pressing the reset button—is counterproductive. It will only lead to crumpled masters, ink on the pressure roller, or costly damage to the drum’s mesh. riso error a16-525

: If the drum's "Position-A" is slightly off, the sensor may be looking at the shiny metal of the drum instead of the black absorber strip. 3. Troubleshooting Steps

Generic replacement screens sometimes use lighter materials that reflect more light, triggering this error. Step-by-Step Troubleshooting 1 Manual Removal

The Riso shines a light at a small black velvet strip on the drum. Wait approximately 60 seconds to allow the internal

Use a soft cloth to wipe paper dust or ink off the small black velvet strip near the drum clamp. Restores the strip's light-absorbing properties. 3. The "Sharpie Trick"

If physical cleaning doesn't work, you may need to clear the machine's state:

Before you begin, ensure the machine is turned off and unplugged to prevent any accidental electrical shocks or mechanical movements. Primary Meaning: Awaiting Master Removal At its core,
