2.1.5 Print Head Element Check
This function is used to check for any broken thermal elements of the print head.
If blurred print or missing dots occurs, this check helps you find whether the thermal elements are actually
broken or the print head is just stained.
Also, use this check just after a replacement of a print head to find an initial failure.
When the Self-Diagnostic Test result is printed, the message returns to “<1>DIAG. Vx.x”. Press the
[PAUSE] key three times and [FEED] key twice.
The printer is ready to check the print head to see if there is any problem with the print head. Press the
[PAUSE] key to start.
If there is no problem with the print head, the print head check is complete. Press the [PAUSE] key to
return to “<1>DIAG. Vx.x”.
If there is a problem with the print head, the following message is displayed.
Press the [PAUSE] key to return to “<1>DIAG. Vx.x”.
NOTES: 1. Make sure that the Top Cover is closed before starting the print head check.
2. If “HEAD ERROR” appears, the print head element may be damaged. Replace the print head.
3. The print head element check can be performed at the power on time.
For selecting this function, refer to Section 2.2 Parameter Setting.
