1. Connect the printer signal cable firmly to the correct parallel, serial, or USB connector on the
computer.
2. Load the paper correctly.
3. Turn on the printer and keep the printer online.
• If you are using non-IEEE-approved printer signal cables, do the following:
1. Correctly install device drivers and software that come with the printer.
2. Assign the printer port correctly in your operating system, application program, or BIOS settings. For
more information about BIOS settings, see "Using the Setup Utility program" on page 59.
If the problem persists, run the tests described in the documentation that comes with your printer. If you
cannot correct the problem, have the computer serviced. See Chapter 12 "Getting information, help, and
service" on page 129.

Serial connector cannot be accessed

device has its own power cord, attach the power cord to a grounded electrical outlet.
• Turn on the serial device and keep the device online.
• Install any application programs supplied with the serial device. Refer to the documentation that comes
with the serial device for more information.
• If you added one serial-connector adapter, install the adapter correctly.
