Upper cover lock switch (L) / (R)
The microswitch-based upper cover lock switches detect the open/closed states of the upper cover.
When the upper cover close, the switches are pressed to detect the closed state of the upper cover.
The printer has one switch installed on the left and right sides each to prevent one-sided closure of the upper cover.
Ink tank cover switch
The microswitch-based ink tank cover switch detects the open/closed states of ink tank cover.
When an ink tank cover closes, the switch is pressed to detect the closed state of the ink tank cover.
Pinch roller pressure release switch
The microswitch-based pinch rollerpressure release switch detects the status of the paper release lever.
When the paper release lever closes, the switch is pressed to detect the closed state of the paper release lever.
Lower roll unit release detection switch (L)/ (R)
The microswitch-type lower roll unit release detection switches detect the mounting of a lower roll unit in the printer. Mounting a lower roll unit in the printer
depresses the switches, causing them to detect the mounting of a lower roll unit.
The printer has one switch located on the left and right side each to detect with confidence that a lower roller unit is mounted in position.
