Thermal Transfer (TT).
Switch 5: Head Check On/Off
Enables or Disables the printer function that automatically
checks the print head for open circuits. On detecting a
head error along any part of the print head, the ERROR
LED will be lit continuously. The printer will not allow any
further operation unless the following buttons are press, or
certain actions are taken.
1) Press the ONLINE and FEED buttons for five seconds.
The ONLINE LED lights for a brief moment, and then the
printer is taken OFFLINE. Restart the printer to continue
printing as per normal.
2) The printer can be set to two types of Head Check Processes. The first check process is termed
“Barcode”, where only barcodes printed via the printer’s built-in functions are checked to detect the
presence of print element failure. The other check process is termed “Normal”, wherein all printed
areas (whether it is text or graphics or barcodes) will be checked to detect the presence of print head
problems.
