The contents of the maintenance counter are as follows:
Hexadecimal Decimal Amount of data
Header 5FH 95 1 byte
Data 30H – 39H 48 – 57 1 – 10 bytes
NUL 00H 0 1 byte
[Notes] • The printer transmits [Header + Data + NUL] collectively without confirming whether the host
is ready to receive data. To receive all data correctly, adequate capacity is required in the
receive buffer of the host.
• During the transmission of block data values in the maintenance counter, the printer ignores
the real-time commands. Also, the printer does not transmit ASB even when the ASB is
enabled. Therefore, the user cannot confirm changes in the printer status during these
periods.
• The counter values may be different from the actual counts depending on time differences at
power off or the occurrence of an error.
