TROUBLESHOOTING Troubleshooting With LED Error Indications 33
3.2.1 Fatal Error
Check the parts according to the contents of the fatal error, and replace the parts as necessary.
C H E C K
P O I N T
As the most recent fatal error (fatal error code) is stored in the
EEPROM (Address: 0AH), it is possible to check the error by using
the adjustment program.
Classification Item Description Remedy
DC Error PID aveTi max Error Something is wrong with the CR motor. Check the parts listed below, and replace them as necessary.
• CR Motor
• CR Encoder
• CR Encoder Scale
• Timing Belt
• Main Board
• Connectors and harnesses of each motor or encoder
PID Overspeed Error Carriage movement speed is abnormal.
PID Lock Error Carriage has been locked for a certain period of time due to
external factors.
PID Reverse Rotation Detection Error The number of the carriage reverse rotation has exceeded the
predetermined times due to external factors.
Encoder Abnormality Error (CR Driving
Time Over Error) One-pass movement cannot be completed though the CR
motor has been driving longer than the specified time.
Load Positioning Overspeed Error Abnormal carriage movement speed is detected during load
positioning control.
Load Positioning Lock Error It is detected that the carriage has been locked for a certain
period of time during load positioning control.
Load Positioning Cumulative Movement
Distance Error The cumulative movement distance during the load
positioning control has exceeded the given level
Head Error Transistor Environment Temperature
Abnormality Error The environment temperature of the transistor that generates
head driving waveform on the Main board is abnormal. Check the parts listed below, and replace them as necessary.
• Printhead
• Head FFC
• Main Board
Pre-printing X-HOT Detection Error During pre-printing X-Hot detection, the temperature of the
head driver IC has exceeded the given level for more than two
seconds.
Post-flushing X-HOT Detection Error During post-printing X-Hot detection, the temperature of the
head driver IC has exceeded the given level for more than two
seconds.
