6.5.13 Charge-related faults and Occurrence conditions
-
The charge-related faults and their occurrence conditions are described below model by
model.
Model KX
Faults
Ink ejection
Occurrence conditions
No Ink Drop
Charge
Stopped
This fault is determined by APH waveform in only
“Ready” state.
This fault is issued when APH signal is not detected in a given
time. The ink stream bending is detected.
Ink Drop Charge
Too Low
Stopped
This fault is determined by APH waveform in only
“Ready” state.
This fault is issued when APH signal level is lower than its criteria
in a given time.
Low-charged ink drop is detected because the ink drop is not good
in shape, or the ink stream bending is detected.
Ink Drop Charge
Too High
Stopped
This fault is determined by APH waveform in only
“Ready” state.
This fault is issued when APH signal level is higher than its criteria
in a given time.
The electrical leakage noise or the external noise is detected.
Model UX, RX2, RX, PXR and PX
Faults
Ink ejection
Conditions that the fault occur
No Ink Drop
Charge
Stopped
(Ink ejection is
kept in case of
Service
personnel
maintenance
mode)
This fault is determined by APH waveform in
“Standby” as well as
the
“Ready” state.
This fault is issued when APH signal is not detected in a given
time. The ink stream bending is detected.
However, when IJP is in Service personnel maintenance mode,
ink ejection is continued for troubleshooting.
(This fault is issued when the ink drop is not charged even though
the ink is ejected. If that is the case, it is necessary to find
whether the ink drop is not good in shape or whether charge
voltage is not output.)
Ink Drop Charge
Too Low
Stopped
This fault is determined by APH waveform in only
“Ready” state.
This fault is issued when APH signal level is lower than its criteria
in a given time.
Low-charged ink drop is detected because the ink drop is not
good in shape, or the ink stream bending is detected.
Ink Drop Charge
Too High
Stopped
This fault is determined by APH waveform in only
“Ready” state.
This fault is issued when APH signal level is higher than its
criteria in a given time.
The electrical leakage noise or the external noise is detected.
