Chapter 4 More Sophisticated Fault Isolation Tasks
3-1
1. 【2F13】AD converter external trigger output error
(HW-1 fault)
Occurrence
conditions
The carriage is unable to travel since the motor is switched off after the occurrence of some error
during printing, disabling pulse (head ejection timing signal) input from the carriage encoder.
Carriage operational
failures
C2
Abnormal carriage drive load
Carriage motor drive at electrical fault
Faulty carriage encoder sensor
Failure
causes
Faulty main
controller
C3 Faulty main controller
※AD Converter External Trigger: Head ejection timing signal
Cause
Point to check Action
C2 Faulty carriage idler pulley (broken spring hook, belt coming off) Take corrective
action.
C3 If the error occurs before the start of printing, the main controller is most likely faulty. Replace
C2 Check carriage components other than the idle pulley for operational failures. 2F26 (P3-4)
The problem is reported to have occurred as a result of a faulty cutter, depending on
the version of firmware.
2015 (P3-17)
Check to see if any other operational failure has not occurred (browse through Print
Inf for a log of error occurrences).
Take corrective
action.
