Explanation/Detection sequence
Carriage shift timeout
The target position could not be reached
within a predicted operation time +3
seconds during carriage operation.
Lift shift timeout
A lift operation has been executed, but no
sensor has been detected or a sensor has
remained detected.
LF feeding motor timeout (cut sheet)
-The target position could not be reached
within a predicted operation time +3
seconds during an LF operation.
-The sensor could not be detected during an
LF operation involving sensor detection.
Cannot detect the LF home position
The LF home position could not be
detected on LF homing during
initialization.
LF operation failure (LF operation
disabled)
A pump duty of 100% has lasted for 200
msec during LF operation.
Cassette shift timeout
-The target position could not be reached
within a predicted operation time + 3
seconds during cassette operation.
-No sensor has been detected during a
pump operation involving sensor detection.
Cassette operation disabled
A PWM duty of 100% has lasted for 200
msec in a cassette operation.
Roll shift timeout
No sensor has been detected during a roll
operation involving sensor detection.
Remedial Action
<Supplement>
-If the carriage travels heavily towards
the stop position, a mechanical load
error may be suspected.
1. Switch off the printer, then back on.
2. The carriage cannot travel to the lift
drive position.
3. The lift drive cam is not engaged.
4. Faulty lift drive sensor
5. Faulty lift drive motor
1. Replace the feed roller encoder
sensor.
2. Replace the feed motor.
<Supplement>
-If the carriage travels heavily near the
stop position, a mechanical load error
may be suspected.
-If any other symptom is observed, a
feeding sensor may be at fault.
1. Check the sensor (I/O mode check).
2. Replace the feed roller encoder
sensor.
3. Replace the encoder film.
4. Replace the feed motor/belt/ adjust
the belt tension.
5. Replace the long flexible cable.
<Supplement>
-If the motor could not be run at all:
A. A mechanical load error may be
suspected.
B. The motor or drive circuit may be at
fault.
-If the carriage has resulted in an error
after moving at a constant speed: The
feed roller HP sensor may be at fault.
-If the carriage has run more or less out
of control and resulted in an error, the
encoder sensor may be at fault.
When FU2802 blows out on iPF6300/
6400 series
-Replace the main controller PCB.
1. Replace the feed roller encoder
sensor.
2. Replace the feed motor.
<Supplement>
-If the motor could not be run at all or
has resulted in an error after moving by
a slight distance:
A. A mechanical load error may be
suspected.
B. The motor or drive circuit may be at
fault.
-If the carriage has run more or less out
of control and resulted in an error, the
encoder sensor may be at fault.
When FU2802 blows out on iPF6300/
6400 Series
-Replace the main controller PCB.
<Supplement>
-If the carriage travels heavily near the
stop position, a mechanical load error
may be suspected.
-Otherwise, the cassette unit sensor
may be at fault.
1. Check the cassette motor and the
drive circuit.
2. Check the cassette encoder sensor.
