5.5 No Information Is Printed
If the printer appears to be operating correctly but no data is printed, check the
following:
• Is a valid design selected?
• Check that the print speed and contrast values are at appropriate levels for
the thermal ribbon and substrate.
• Is the printhead coming into full contact with the print platen / roller across its
full width?
• Is the correct ribbon loaded with the inked surface away from the printhead. Is
it driving correctly?
• Check that the air supply is at the appropriate pressure.
• On continuous printers, the encoder signal may not be providing the correct
speed information.
• The printhead may be faulty.
5.6 The Printhead Does Not Move Out
The Printhead in / out motion is driven by a small pneumatic solenoid. If the head
does not move out, use Manual mode to test the operation of the solenoid. Check
the following:
• Check the air supply pressure and the pipe work between the components.
• Check that the head is free to rotate in its mounting.
• Check the solenoid wiring.
• Replace the solenoid and / or the air cylinder as required.
• If the fault persists, replace the Printer PCB.
