Chapter 2: Diagnostics and Configuration

Runtime diagnostics

Runtime diagnostics (sometimes called level 2 diagnostics) run during normal printer operation.

When the following conditions occur, the printer automatically turns off the appropriate motors

and disables printing to prevent damage to the printer:

• Paper out

• Receipt cover open

• Knife unable to home

• Printhead too hot

• Voltages out of range

The LED on the operator panel will signal when these

conditions occur as well as indicate what state or mode the

printer is in.

Remote diagnostics

Remote diagnostics (sometimes called level 3 diagnostics) keeps track of the following tallies and

prints them on the receipt during the print test. See the sample test printout on the next page. These

tallies can be used to determine the printer’s state of health.

• Model number

• Serial number

• CRC number

• Number of lines printed

• Number of knife cuts

• Number of hours the printer has been on

• Number of flash cycles

• Number of cutter jams

• Number of times the cover is opened

• Maximum temperature reached

(See tallies note on the following page.)
