Startup track mode
Introduction
The startup track mode is designed to enable you to identify a failing
subsystems while the printer is initializing. Startup track mode provides a
specific indication of which particular subsystem is failing. This mode is not
intended for use by end-users.
Initializing the printer in Startup track mode
To initialize the printer in Startup track mode:
1 Hold the ’Continue’ button while connecting the printer to the power supply.
2 During the initialization of the printer, the front panel will display a range of
code numbers in the form of squares, these code numbers added together
represent the various subsystems about to be initialized.
3 Once the printer comes to initializing the failing subsystem, the front panel
will hang, and all that will be displayed is the failing subsystem.
Interpreting the numbered code system
While the printer is initializing, the front panel will display a sequence of
squares in the last two columns. Each position in the last two columns
represents a number, all the numbers represented are shown below. To find
the failing subsystem, add the numbers together that have a square and refer
to the list of numbers with their associated subsystems page 20.
In the example below the printer is initializing and the front panel has
stopped and is displaying squares in positions 16, 32, 64 and 4. Add these
four values together and you get 116, refer to the list on page 20, and we
can see the failing subsystem is the Trailing Cable.
If the display reaches 191, you will need to turn On the printer from the
power button. If all the subsystems pass the initialization, the printer will
initialize normally and go to the ready status.
