Printer Protection For Heavy-Duty Printing - Epson LQ-510 Technical Manual

GENERAL DESCRIPTION

1.8.9 PRINTER PROTECTION FOR HEAVY-DUTY PRINTING

The printer incorporates "printhead protection" to safeguard it from overheating and from the potential ill
effects of a voltage drop to the head driver. If the temperature of the head exceeds a specified value, printing
is automatically suspended. Printing automatically resumes when the temperature drops to another specified
value.
If heavy-duty printing causes the voltage to the head drive circuit to drop to a specified value, printing is
immediately suspended. If the voltage recovers, the line that was being printed is completed. This protection
occurs when half or more of the wires are activated simultaneously and continuously.
