Troubleshooting
No print
•
Check the
red lights
on the control panel. They remain off until the photocell is
triggered, when one or both come on and flicker as the unit prints. If the light comes on,
make sure it is the top light if you have only one print head cable plugged in, which
should be plugged into the top connector. If neither light flickers, you are printing the
wrong message, the message is blank or the 40 volts fuse on the power supply has
failed.
•
Check the
ink level
and the ink tube to the head is full of ink.
•
Is there
air pressure
in the bottle. Gently remove the quick disconnect air fitting from the
bottle cap. It should hiss as air escapes. If it does not, check the air pump operation.
Check the
box counter
. Does it increment when the photocell is triggered? If so, the unit is
printing something so check:
•
The screen shows ‘Msg XXX printing’. Is XXX the message number that you want?
•
Edit the message. Does it have something in it to print?
•
Is the dotsize between
150-180
If no, then check
•
Is the photocell seeing the box. Look for the led on the photocell lighting up when the
product is in front of it. Clean the photocell if necessary
NB
switch the unit off first to
avoid ink being ejected into your eyes as you wipe the photocell.
•
Is there any ink being ejected from the nozzle plate? If yes, check the
delay settings
to
see if the printer is printing after the box has gone.
•
If no, try
purging the head
. If still nothing, replace the ink filter and re-test.
Dots missing
Purge first of all. Are some of the jets twisting and not straight? If so following the instructions
given under routine maintenance to clean the nozzle plate.
If after cleaning the nozzle plate you still have no print you may wish to consider sending the
head back to your supplier to have the valves adjusted or the head overhauled. If you wish to
adjust valves yourself, follow the instructions under Advanced Maintenance.
