Problem Solving
What if …
…nothing happens when I turn on the printer?
The printer may not be plugged in. Check the power cord connection to the outlet
and to your printer. If you’re using a power strip, make sure it’s turned on. Check to
be sure that the fuse hasn’t blown or that the circuit breaker hasn’t tripped.
…the printer doesn’t print when the computer sends data?
The printer may be deselected. If the SEL light is out, press the SEL button to select the
printer.
The printer cable may not be securely connected. Check the cable to be sure that it is
properly connected to both the PC and the printer.
If you have installed the serial I/F board, check to be sure that the board is firmly
seated in the printer.
