(Once every two seconds)		 Printer cooling down

The thermal head or motor is too hot.

Head:
The printer stops and resumes printing only after the thermal head has cooled down.  The head may become too hot if you are printing a large number of documents with high text content.
If the thermal head becomes too hot, it may produce imaging on the paper in areas not intended to be printed.
To avoid or delay overheating, use a lighter density setting, reduce the amount of black space being printed (for example, remove background shading and colors in graphs and presentation documents), and make sure the printer has adequate ventilation and is not located in an enclosed space.

Motor:
Continuously using the printer will cause the motor to heat up.  If it becomes too hot, the printer will stop and resume printing after the motor has cooled down.

This condition may occur more often when the printer is used at high altitude (more than 10,000 ft (3,048 m)) due to a lower air density available to cool the printer.
