Cover Open Detection Sensor - Tally Dascom DL-210 Maintenance Manual

1.1 Cover open detection sensor

Remark:
The cover open detection sensor is a switch-mode sensor assembly, in order to detect
whether the print head is open or closed. When the print head is open and the printer is
on, the printer will give an error LED alarm, which indicates the print head is open.
Please note that this sensor will not detect whether the top cover is open or not.
During firmware update the print head along with the top cover should be open,
otherwise users cannot proceed with firmware updating.
