Causes Troubleshooting Steps
A short on the PCB.
Main power supply
voltage is not adjusted
properly. Main power
supply has failed. DC voltage measurement between TP11 (ground) and TP8
should read 30 volts +/- 1%. If voltage is out of speci
fi ca-
tion, check power supply connections and main power
supply output. Contact Ioline Customer Service for more
information if the voltages are out of speci
fi cation.
On-board regulator
failed. Main power
supply failed. DC voltage measurement between TP11 (ground) and TP8
should read 3.3 volts +/- 5%. Return logic board to Ioline
for service.

Over-current condi-
tion on circuit due to
a short or high heat. Check the motor connections and motor to ensure there are
no shorts to ground. A hardware problem with the motor
drive circuit. Return the board to Ioline for service.

Over-current
condition on circuit
due to a short or

ensure there are no shorts to ground. A hardware prob-
lem has occurred with the power switch for the carriage
printhead power. Return the board to Ioline for service.
Motor jam.
Software error. Remove issue causing motor jam. Cycle power on ma-
chine. Update to latest
fi rmware.
