Thermal Printer C-56
Part No. 2 684 019 Rev. No. 4310715 eli page 9 of 17
Optional reflective LED sensor L4 is located on the left outside of the paper reservoir and detects when the
diameter of the paper roll decreases below a fixed dimension, indicating that paper is low. This is a hardware
alternative to the default paper low system, which requires thermal paper with black marks at the end of the
paper roll. The status of L4 can determined via the Query command and is reported as part of the C-56 status
bytes. See the C-56 Emulation Manual D 684 017 for details on querying this sensor and the format of the
response.
In case of any trouble during paper feed, the printhead can be lifted from the platen manually
using the “printhead up” lever so that the paper can be pulled out of the printer mechanism.
Caution !
Do not lift the printhead during printing or the thermal printhead may be damaged or destroyed
by overheating.
