Troubleshooting
6-8
Box to be printed is out of the
photocell sensory range.
(If the box is out of photocell
range, the photocell LED will not
change color when the box passes
it.)
Adjust the photocell so that it is
closer to the box.
Photocell is not connected to the
controller.
(If the photocell isn’t connected,
the printhead and photocell LEDs
won’t change when a box passes
infront of the photocell.)
Connect the photocell and make
sure it is activated. (See “Setting the
Print Trigger” on page 4-15.)
Internal photocell is selected.
Select external photocell.
The photocell is defective
Replace the photocell.
The message is set to print on
lines that have no printheads
assigned.
(If the message is on a line with
no printhead assigned to it, the
printhead LED will turn red
when the photocell is tripped,
and then go back to green.)
1. Edit the message so that the
lines of print are set appropri-
ately for the printhead configu-
ration (i.e., the message is
typed on the same lines that
the printheads will print).
OR
2. Reconfigure the printhead
setup so that the lines in the
message will print. (See
“Printhead Configuration” on
page 4-9.)
If applicable, shaft encoder or its
adapter cable is defective.
Perform continuity check; if
necessary, replace shaft encoder
adapter cable or entire shaft
encoder.
You are dual-tasking, but the View
Task function key will not switch
between tasks.
The Task 2 Key has been
removed.
Install the Task 2 Key. (See “Task 2
Key Installation for Dual Tasking”
on page 3-22.)
Message is not printing on every box
(skips boxes consistently or
randomly).
Box is just at or below the
photocell sensors.
Lower the photocell.
Message is missing lines.
Line speed is not constant.
Perform continuity check; if
necessary, replace shaft encoder
adapter cable or shaft encoder.
