HUMMER VOLTAGE ERROR

There are two different Hammer Voltage errors on the 6306; Hammer Voltage 1 and Hammer Voltage 2.

Hammer Voltage 1:

One of the hammer drive circuits was turned on when it shouldn’t have been, so all printing has been disabled. The usual cause is a failed drive transistor.

Solution: Replace the Controller Board.

Hammer Voltage 2:

A high resistance coil fault has likely occurred in one or more of the hammer coils. Note: this fault message will have been preceded by printing slow-down attempts associated with On-The-Fly thermal monitoring of hammer bank temperature.

Solution:

Check the hammer bank for defective coils.
Replace the Controller Board
