RISO Error A16-525: Understanding and Troubleshooting the Issue

General Troubleshooting Steps

  1. Ink Supply Issues: The error often arises from problems with the ink supply, such as low ink levels, clogged ink tubes, or issues with the ink cartridges themselves.
  2. Faulty Sensors: The printer relies on sensors to detect ink levels and monitor the ink supply system. A malfunctioning sensor can incorrectly report ink levels, leading to this error.
  3. Clogged Print Head: A clogged print head can disrupt the ink flow, causing errors related to ink supply and detection.
  4. Electrical or Mechanical Failures: Issues with the printer's electrical circuitry or mechanical components, such as pumps or valves controlling the ink flow, can also trigger this error.

  1. Turn off the printer, wait 30 seconds, then restart.
  2. Open the master-making unit and check for any loose connectors.
  3. Gently clean the thermal head with a soft, dry cloth.
  4. If the error persists, you may need a technician to replace the thermal head or cable.
