Self-test Error Messages
Self-test diagnostics are run:
!
During the power-on sequence.
!
After initialization by either the control panel keypad.
!
After printing.
!
When requested from the host by the ESC Q escape sequence.
(See
Programmer’s Manual
for information on escape sequences.)
The following table shows the display message, fault, and error
message. (The error message is used only when requested by ESC Q -
See note.) The fault column indicates which circuit board is defective.
NOTE
The error message is used only in the ANSI emulation while
using the serial interface. When an ESC Q escape sequence is
received, the printer performs a self-test and sends the
appropriate error message to the host if a fault is found. DCS =
ESC P and ST = ESC \. See
Programmer’s Manual
for information on
the ANSI emulation and escape sequences.
