Explanation
Controller voltage failure.
Corrective Action
1. Make a configuration printout and note the customer's code load
(if possible).
2. Power down and unplug the printer.
3. Replace the hammer bank logic cable. There may be damage you
cannot see.
4. Power on the printer. If the problem persists, do the cable shorts
test (page 254) on the hammer bank (HB) power cable. Replace
the cable if necessary.
NOTE: When reconnecting the HB power cable, make sure pin 1 on
the cable connector matches pin 1 on the PCBA connector.
Plugging the HB power cable in backwards can result in a
"Table Mismatch" error.
5. Make sure the cables are properly tie-wrapped away from the
reciprocating shuttle. Spin the shuttle motor by hand to check that
the cables are clear of the shuttle as it moves.
6. You can easily verify that when the shuttle cover is installed, the
hammer bank logic cable is clear of the shuttle by removing the
paper scale on the shuttle cover, as follows:
a. Remove the paper scale BEFORE installing the cover to
reduce the chance of losing a screw in the machine. Mark a
location reference line with a pencil across the paper scale
and cover. Remove the three screws holding the paper scale.
b. Install the shuttle cover and fasten it in place. Look in past the
shuttle cover to verify the position of the hammer bank logic
cable. If it is near the shuttle, remove the cover and push or
tie the cable back.
c. When the cable position is OK, install the paper scale, being
careful not to drop any of the three screws. Erase the pencil
line.
