P1016701-001 KR403 Integrators Guide 12/23/2009
Status conditions are reset and rechecked when:
1. When the conditions causing them are removed
2. When the printer has power removed and reapplied.
3. When the printhead is opened or closed.
Sensing, Status and Error Reporting
The KR403 has an extensive array of sensing and error reporting capability available to the
printer for internal process control, status reporting to the host and custom printer software
development by the software integrator. Many of these features and functions are supported
directly by the Windows Driver and Zebra Designer via the driver.
• The printer monitors the printhead, motors, cutter and a variety of internal main board
functions.
• The KR403 printer has a variety of ‘virtual sensor and error flags’ that use
combinations of sensors and status flags to create additional error reporting flags to
simplify the software integrators task of monitoring the printer.
• The KR403 printer also has an odometer for maintenance alerts for printhead cleaning
and printhead low life warning (printhead will need replacement soon). This feature is
off by default.
• The KR403 printer also does power-up printhead testing, printhead critical fault
testing for safety and has a programming accessible printhead pixel test that reports
the functionality of individual pixels. This feature is off by default.
