Printer Tests
These tests are used to check the print quality and operation of the printer.
NOTE: Your authorized service representative will typically run the tests.
They are described in more detail in the Maintenance Manual.
• Checkerboard. This pattern helps identify marginal printhead elements,
quality of edge sharpness, and uneven print quality.
• Grey. This pattern helps identify burned out printhead elements and
uneven print quality.
• Grid. This pattern helps identify edge sharpness and uneven print quality.
• Current Config. Prints the current printer configuration and helps identify
the text print quality.
• Left Test. This pattern contains a series of ladder-type bar code symbols.
The first prints four ladder symbols and the last prints a single ladder
symbol. This pattern helps to identify ribbon wrinkle problems.
• Right Test. This pattern contains a series of ladder-type bar code
symbols, starting with four, and decrementing by one symbol on each
print until a single symbol prints. This pattern helps to identify ribbon
wrinkle problems.
• E-Net Test Page. Prints the Ethernet statistics stored on the Ethernet
adapter (if present).
