S Self Test
S PRINT TEST 1 (see Chapter 1.12 Test Printouts)
S PRINT TEST 2 (see Chapter 1.12 Test Printouts)
S PRINT TEST 3 gives information about technical releases and is
intended for service purposes only. Among other
information, the page counter identifies the number
of pages printed.
S I/F Test This function is used to test the serial interface. It
enables test data to be sent out from the printer
and returned by means of a closed loop connector
data used consists of PRINT TEST 1.
S Hex Dump
This function makes it possible that the data received by the printer can
be analyzed. Control codes are no longer carried out, instead all data is
printed in hexadecimal format and as ASCII characters. Any non--
printable characters, such as carriage return are only represented as a
single dot (.) in the ASCII list.
It may happen that the transmission of data to the printer will be
interrupted during Hex Dump. In this case, printing of data received after
the break is started on the next available line. The result is an irregular
right margin which is not an indicator for any loss of data.
