Chapter 3: Troubleshooting
3–13
Printed output appears shaky or fuzzy
There are six things that can cause this problem.
1. The Form Thickness Lever may be open too far but not far enough to cause a
Platen Open
message.
2. The shuttle mechanism is worn—the shuttle counterweight gears or the bearings
are worn.
3. The hammers are not firing properly.
4. Platen alignment may be incorrect.
5. Damaged platen.
6. The Shuttle Sensor is misaligned.
Troubleshooting Procedure
STEP 1.
Check the Form Thickness Lever and make sure it is closed properly.
STEP 2.
Check the Shuttle Mechanism for wear in the gears or play in the bearings.
If the Shuttle Mechanism is defective, replace the Shuttle Mechanism, then perform a
Hammer Calibration procedure for optimum print quality.
STEP 3.
Perform a Hammer Calibration procedure. This procedure is explained in
Chapter 2
, in
the
TEST
Menu Section, under the
Diagnostic
Category (
PrntCal
Parameter).
If the hammers can not be calibrated, the problem is in the Engine Controller CBA.
Replace the Engine Controller CBA following the procedure explained in
Chapter 4
.
STEP 4.
Check and adjust the platen alignment guides. The Platen Gap should be .012 " – .014"
with the Form Thickness Lever fully closed.
STEP 5.
Check the impact area of the platen and replace the platen if this area is damaged.
STEP 6.
Make sure the Shuttle Sensor is properly aligned. (See
Procedure 18
in
Chapter 4
.)
