Runtime Errors

6820 Series 80-Column Printer User's Manual
4 Push the printer mechanism to the right away from the green thumb
wheel.
5 Press on the right side of the printer mechanism to the back as far as
it will go.
Note: In this position, the right back edge of the printer
mechanism may touch the pivot frame. The left side must
not touch the pivot frame.
6 Hold the printer mechanism in place and tighten the screws in the
sequence shown below.
Printer errors are divided into classes:
•
Runtime errors
•
Power-On-Self-Test (POST) errors
• Fatal errors (consisting of flash write errors and EEPROM block
errors)
Runtime errors can occur during the course of printing. These errors are
displayed on the LEDs, along with beep sequences. This causes the
printer to stop printing and enter an error state. Then beep sequences are
emitted, LED codes are displayed, the error status may be sent to the
host (depending on the protocol), and the printer goes into suspend
mode.
The printer exits from the suspend mode when the user presses one of
the keyboard keys or communications is resumed from the host. The
printer also places the printhead in its home position and attempts to
recover from the error condition. Until the error condition is corrected,
the error procedure does not end, and the error state is not removed.
