After mechanical fix:
In the Riso hierarchy of error codes, the prefix A16 refers to the Ink Supply System. Specifically, it usually indicates that the machine detects a discrepancy between the ink levels detected by the sensors and the physical state of the ink cylinder or ink cartridge. riso error a16-525
The specific code 525 typically relates to the Ink End Detection or Ink Cartridge Recognition failure. Essentially, the machine believes the ink is exhausted or cannot confirm the presence of a valid ink cartridge, even if you believe the ink is full. After mechanical fix: In the Riso hierarchy of
If the sensor works but the error persists, the mechanical timing is off. This requires a Service Adjustment (Standard Adjustment) . riso error a16-525
