SERVICE REQ. 00010004: CR ENCODER CHECKING ERROR
o
Problem
CR motor encoder check error
The CR motor makes small revolutions clockwise and counter-clockwise. When it
turns, the printer checks the encoder output signals to make sure the motor is
turning at the correct speed/distance. If the encoder doesn't send the correct signal
or output data, an error occurs.
n
Encorder cable disconnection
n
Encoder sensing phase A or B misconnection
n
Encoder connector disconnection
n
Motor cable disconnection
n
Motor cable misconnection
o
Solution
It confirms whether there is not abnormal load etc. at the time of carriage
migration and be abnormal no and do the checking of the CR encoder, in the case
that the error is not canceled.
In the case that there is abnorm :
Carry out the tension of the steel belt adjustment or CR motor exchange.
In the case that there is not abnorm :
Confirm whether there are not dirt and damage in the CR encoder.
The cable connector joint to the CR encoder and head Assy board CN15 are confirmed.
Encoder pulse detection for T fence (scale 180a) of it comes off/whether or not there is
not the contact with a CR encoder
n
Confirmation of the dirt/paper powder/damage of the confirmation T fence (scale
180a) the top
n
CR encoder exchange
n
CR motor exchange
n
C362DRV board exchange
Troubleshooting
SERVICE REQ. 00010005: CR MOTOR STEP-OUT
o
Problem
The rotational speed of the CR motor abnormal. (it is long/short period at the time
of prescription ).
o
Solution
It confirms whether there is not abnormal load etc. at the time of carriage
migration and be abnormal no and do the checking of the CR encoder, in the case
that the error is not canceled.
In the case that there is abnormality:
n
Encoder pulse detection for T fence (scale 180a) of it comes off/whether or not
there is not the contact with a CR encoder
n
Tension adjustment of the confirmation steel belt
n
Confirmation of the dirt / paper powder / damage of the T fence (scale 180a) the
top
n
CR encoder exchange
n
CR motor exchange
n
C362DRV board exchange
SERVICE REQ. 00010006: CR MOTOR OVER CURRENT
o
Problem
CR motor overcurrent - Feedback from the CR motor (IC33) driver's 10-pin
output (Sense signal) indicates that the CR motor's current is irregular.
o
Solution
n
He resistance value (5.56 ) the measurement of the n CR motor. In the case that
the CR motor exchange motor coil is short condition if there is abnormality
exchange.C362DRV board exchange even the C362DRV board
n
C362DRV board exchange
