FP-550F 19
some of the entries which have tax rates.
- Unidentified form of the fiscal memory module;
- If during the fiscal memory check up (immediately after switch ON) more than three
invalid control sums from a daily report fiscal entry are found.
The current status of the device is coded in a field 6 bytes long which is sent within
each message of the fiscal printer.
Description of each byte in this field:
Byte 0: General purpose
0.7 = 1 Reserved
0.6 = 1 Reserved
0.5 = 1 General error - OR of all errors marked with #
0.4 = 1 # Failure in printing mechanism
0.3 = 1 Not used
0.2 = 1 The clock needs setting
0.1 = 1# Code of incoming command is invalid
0.0 = 1# Incoming data has syntax error
Byte 1: General purpose
1.7 = 1 Reserved
1.6 = 1 Reserved
1.5 = 1 Printer cover is opened
1.4 = 1# RAM failure after switch ON
1.3 = 1 # Not used
1.2 = 1# Operational memory closure has been performed
1.1 = 1# If command cannot be performed in the current fiscal mode
1.0 = 1 If during command some of the fields for the sums overflow.
Status 1.1 will also be set and the command will not cause
changes to the data in the printer.
Byte 2: General purpose
2.7 = 1 Reserved
2.6 = 1 Not used
2.5 = 1 If a non-fiscal receipt has been opened
2.4 = 1 Not enough journal paper
2.3 = 1 A fiscal receipt has been opened
2.2 = 1 Journal paper end
2.1 = 1 Not enough paper - both journal and receipt paper rolls.
2.0 = 1# No paper - valid for both paper rolls. If the flag is raised during a
print-related command it will be rejected and the status of the
printer will remain unchanged.
