NOTE: Procedures in this section are intented for qualified maintenance personnel.
Q1
The system is not printing and the power LED is not lighted. Why?
S1
The printer does not have power. Check the following:
[1] The round plug connection at the base of the controller;
[2] The cable connection at the base of the power supply;
[3] The round plug for a 15 VDC output;
[4] The cable connection at the rear of the printhead;
[5] The wall receptacle to make sure that it is supplying power.
Q2
The system is not printing and the photocell
LED is not blinking. Why?
S2
The photosensors can not detect the product.
They can be either too far from the product or
dirty. Clean the photosensors and adjust the
printhead within 0.25 inch of the product.
Q3
The system is not printing and the ink LED is
flashing. Why?
S3
The printer is out of ink. Replace the old ink can
with a new can.
Q4
The system is not printing but all LED signals are normal. Why?
S4
The character width setting is too small for the product line speed. Increase the character width
by following the directions in Instruction C3.
Q5

S5
A short-circuit has occurred. Disconnect the round controller power connector, and the printhead.
Connect the round controller power connector, but DO NOT connect the printhead. If the unit
initializes normally, replace the printhead. If the unit does not initialize normally, replace the
controller.
