Printer Failures
A user cannot generally resolve a problem involving defective printer
hardware. On detecting a fatal error, the printer will:
• Stop printing
• Beep four times
• Turn the ONLINE indicator off
• Blink the PAPER OUT indicator (with a FONT indicator lit
indicating the error type).

Turn the printer off and back on, then rerun the same job to check if
the error was transient. If the error recurs, contact your dealer.
