Phaser 840 and 850 Color Printers
5,000: Y axis system (drum)
5,001.41:
YA_HOME_FAIL
Drum-home sensor failure. The drum has turned a full
revolution without seeing the drum-home sensor activate.
Check the Y-axis encoder and I/O Left board. Note: The
Phaser 840 has a separate drum-home sensor. The
Phaser 850 printer’s home sensor is part of the
drum-position sensor.
5,002.42:
YA_POS_FAIL
Y-axis position failure. The drum is not where it should be.
Something is blocking the motion of the drum, the y-axis
belts or motor have failed, or there is a problem with the
Y-axis encoder signal.
6,000: X axis system
6,000.41:
XA_FAULT_MCURRENT
X-axis motor over/under current. Indicates motor coil(s) are
open, or shorted, or the motor fuse has opened.
7,000: Process motor
7,002.44:
PM_FAULT_PROCESS_
MOTOR_STALL
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.
7,003.45:
PM_FAULT_
COMPOUND_
GEAR_SENSOR_BAD
No transitions are observed of the compound gear sensor
when the compound gear should be turning. Perhaps the
sensor is failing, or the process motor to compound gear
linkage is broken.
