Meaning
X axis motor over/under current. Indicates that motor coil(s) are open, or
shorted, or the x-axis motor fuse has opened.
X-axis home position not found. Indicates that the x-axis home sensor
has failed, or something has prevented the printhead motion during a
home operation.
Unexpected x-axis home sensor activation. The sensor has failed, the
motor control is moving the printhead in the wrong direction, or the user
has engaged the printhead restraint mechanism.
A verify of the home calibration failed. After locating the home sensor
transition, the DMC computed x-axis position varied from the home value
by more than the acceptable tolerance.
The electronics report an error while operating the motor in the auxiliary
feeder (the optional lower tray)
The process motor stalled during operation. This has several possible
causes, depending on what the process motor was gear-connected to at
the time of failure.
No transitions are observed of the compound gear sensor when the
compound gear should be turning. Perhaps the sensor is bad, or the
process motor to compound gear linkage is broken.
No transitions are observed of the drum maintenance cam sensor. The
sensor may be bad or the drum maintenance cam may be jammed.
The preheater exit sensor is not being detected, it is either unplugged or
defective.
An expected transition of the cap home sensor did not occur. The home
sensor may be faulty, or the cap motor may not be operating, or the cap
may be jammed and unable to move.
A fault is detected in the web sensors. Check the left and right
maintenance tray sensors and their wiring harness.
The cap/wipe/purge assembly stalled. (This fault does not actually occur
because the mechanism is loose. When the assembly jams, the motor
skips over teeth.)
Malfunction of the ink level sensor in the cyan reservoir. Replace the
printhead.
Malfunction of the ink level sensor in the magenta reservoir. Replace the
printhead.
Malfunction of the ink level sensor in the yellow reservoir. Replace the
printhead.
Malfunction of the ink level sensor in the black reservoir. Replace the
printhead.
