These errors are detected at power-on or initialization just after a reset.
(1) Error types
(2) External signal outputs
(3) Resetting methods
8.2 Operation Errors
(1) Error types
Caution:
The 8.5V upper-limit voltage for VP voltage error is only an assumptive voltage just
after charging the battery when using the battery power. It cannot be normally used. A
normal maximum voltage is 7.2V.
(2) External signal outputs
Memory error
Cutter error
Error
The CPU made a self-diagnosis of the circuit and detected an error with the external
RAM.
With the auto cutter enabled at the function selection terminal (DS1-1), the auto
cutter (ACS-220-5V) is not connected to the cutter connector (CN4).

Error
The printing paper set is not set
The head-up lever is at its up position
A VH voltage is beyond its allowable range (4.2 to 8.5V)
A head temperature is less than 0˚C or 65 ˚C or higher.
When driving the cutter, the cutter is locked due to an external factor (Paper
jam, etc.).
