6.5.23 Status Commands
DC2 'e' n Enable/Disable Automatic Status Transmission
Code 12H 65H n
Function Select whether to send an error status if an error occurs.
Only the least significant bit of n is valid.
n = 0: Do not send an error status.
n = 1: Send an error status.
If error status transmission is specified (n=1), the error status (one byte) is output. If an error
occurs or error status changes, 1-byte error code indicating the cause of the error is
automatically output.
However, an error status is not sent automatically if the Battery voltage state changes.
The initial automatic status transmission is stopped when issued the command.
The bits of the error status indicate the following error states:
Value
Bit Function
0 1
0 Paper out OK Error
1 Head up OK Error
2 V
P
voltage error OK Error
3 Head temperature error OK Error
4 SWDIP switch setting error OK Error
5 Battery voltage state See the list below. See the list below.
6 Battery voltage state See the list below. See the list below.
7 Reserved - Fixed
Battery voltage state Bit6 Bit5
8.0 V or higher 0 0
7.5 to 8.0 V 0 1
7.0 to 7.5 V 1 0
Lower than 7.0 V 1 1
Default n=0 (Does not send an error status.)
DC2 'r' Send Remaining Memory Capacity
Code 12H 72H
Function Outputs the signal that indicates the remaining memory (RAM) capacity. The number of bytes of
the unused memory area is transmitted as a 6-byte hexadecimal number.
If the remaining memory capacity is 6736 (1A50H) bytes, '001A50' is transmitted.
