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.
Figure 28 • Sensor Placement in the Printer
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.
