Status Reporting

The printer is equipped with a number of sensors that report the printer status and various conditions such as out-of-paper, previous printout not removed, etc.

A good practice in unattended printer applications is to check for errors and paper availability before printing.

1.Send a Status Report Query (<ESC><ENQ><6>, see Status Report on page 66) and check that the answer is "No errors"

2.If “Status codes available” is indicated, read out the status message with Status Request (<ESC><ENQ><1>, see Status Enquiry on page 62), and take appropriate actions.

3.Send a paper-near-end query (<ESC><ENQ><2>, see Paper-near-end Enquiry on page 63) to see if the sensor reports low paper level.

4.If paper-near-end is indicated, report the condition to the systems supervisor so that he can schedule a service visit to the printer.

5.Print the printout.

Important • A status reply must be read! Sending a second status query without reading the reply of the first query may lock the printer.
