Technical information

PAUSE Key and CANCEL Key
This self test can be used to verify proper printer operation after parts have been
replaced or adjusted. When activated, the printer prints a maximum of 500 Head
Test Labels. Each label backfeeds prior to printing and feeds forward to the rest
position after printing. A serialized number prints on each label. Press the
PAUSE Key or turn the printer power OFF to stop printing. Refer to Figure 3.6.
FEED Key and CANCEL Key
This self test is normally performed during the manufacturing process or after a
major overhaul of the mechanical assemblies. This test prints seven
pre-programmed formats, first at speed D (6" per second), then the same formats
at speed A (2" per second). The S-300 will only perform this test at speed “A”.
The printer automatically pauses after each format. The sequence of formats is
shown below. Refer to Figures 3.7 through 3.13.

Extended Printer Diagnostics
Additional Diagnostic Tests are available for Printhead Assembly Adjustments.
These Diagnostics Tests are only accessible when the Data Interface Cable is
disconnected from the printer and a Loopback Connector is attached in its place.
The Serial Loopback Connector is a 25-pin “D” Type (DB25P) style with pins 2
and 3 tied together and pins 6 and 20 also tied together.
The Parallel Loopback Connector is a standard 36-pin parallel connector
mounted to a small circuit board. This connector is available from Zebra
Technologies as part # 44680.
For each of these Diagnostic Tests, the printer will “Transmit” the test format
out of the Data Interface Connector to the Loopback Connector. The Loopback
Connector passes the test format back to the printer as Receive Data and the test
format is printed.
