POST Modes
Overview
The following messages appear on the Control Panel in English. POST is unaware of the
language selection and therefore defaults to English. This section does
not attempt to show all
the possible messages from POST.
Normal Mode
Power on the printer without pressing any button."Self-test" is displayed on the first line of the
display. Once POST has completed, control is passed to the operating system.
Restore Factory Defaults Mode
Power on the printer while pressing the <Online> and <Menu> buttons. "Restore Factory
Defaults" appears on the display. Once POST has completed, control is passed to the operating
system, where the factory defaults are set.
Demo Mode
Power on the printer while pressing the <Online> and <Select> buttons. "Self-test" appears on
the display. Once POST has completed, control is passed to the operating system and informed
that Demo Mode has been invoked.
Extended (FIC) Mode
Power on the printer while pressing the <Online> and <Form Feed> buttons. "Extended Test"
appears on the display. In the Extended (FIC) Mode, POST performs an extended RAM test in
place of the DRAM Pattern Test that is invoked during normal operation. This test is performed
on all installed DRAM. Once POST has completed, control is passed to the operating system
with the indication that the Print Quality file should be printed after initialization.
Print Quality Mode
Power up the printer while pressing the <Select> and <Esc> buttons. "Print Quality" appears on
the display. Once POST has completed, control is passed to the operating system with the
indication that the Print Quality files (one at 300 DPI and one at 600 DPI) be printed after
initialization.
Continuous RAM Test Mode
Power up the printer while pressing the <Online> and <Help> buttons. "Continuous Test"
appears on the display. In the Continuous RAM Test Mode, POST attempts to detect the
presence of dynamic faults in all of installed RAM. This test runs continuously until power is
cycled, or until a failure occurs. Control is never passed to the operating system.
Extended RAM Test Mode
If the printer is powered up with the <Item > and <Item > buttons pressed, "Extended Test"
appears on the display. In the Extended RAM Test Mode, POST performs an extended RAM test
in place of the DRAM Pattern Test that is invoked during normal operation. This test is performed
on all installed DRAM. Once POST has completed, control is passed to the operating system.
