1.6.11 Printer Protection
f o r H e a v y - D u t y P r i n t i n g
This printer has a printhead protection function to prevent it from overheating and to protect the printer
when the head driver voltage drops. If head temperature exceeds its maximum value, printing stops
automatically until the head temperature drops to a certain value before printing resumes. Printing
resumes at a lower print speed at first.
However, as the head temperature decreases, print speed increases to normal speed automatically. If
the head temperature continues to increase at the lower speed, printing is stopped or resumed as
temperature increases or decreases.
If the voltage supplied to the head drive circuit drops below its minimum limit as a result of heavy-duty
printing, printing is interrupted immediately. When the power supply voltage recovers to a certain value,
the remaining print line is printed at half speed. This protective action occurs when half or more of the
wires are activated continuously.
