can damage the printer itself. When this situation occurs, an error must be
indicated in order to protect the printer from abrasion.
[Recover action] The printing recovers automatically from this error when the thermal print head
temperature drops below 60ºC again.
[Note] This error can happen if the ambient temperature is very high and the printer
is working continuously with high-density printing.
NO PAPER ERROR / DOOR OPEN
[Description] The out of paper sensor detects there is not paper on the printing line. When
de door is open the printer will also detect it the same way.
[Recover action] This error disappears loading a new paper roll in the printer and closing the
paper door (see section 3.1. Paper loading).
[Note] This error stops the printing and it cannot be restarted until it is not recovered.
This error is indicated in the parallel port depending on the conditions set by
the "ESC c 3" command (See point 4. CONTROL COMMANDS).
