23 times Valve cam
sensor error
[6C10] The valve cam sensor was
faulty at power-on or when
purging was attempted.
1) Foreign material or paper debris
around the purge drive system unit;
remove foreign material.
2) Cable connection
3) Part replacement:
- Purge drive system unit
- Logic board
Note: Before replacement of the logic board ass'y, check the ink absorber counter value (by service
test print or EEPROM information print). If the counter value is 7% or more, also replace the ink
absorber kit when replacing the logic board ass'y. If the counter value is less than 7%, register
the current ink absorber counter value to the replaced new logic board instead.
