What If Your Computer Does Not Work?
Printer Problems
Intermittent Problems
Problem Action
The printer does not work. Verify that:
The printer is turned on and ready to print.
The printer signal cable is connected to the correct connector on the
computer. (For the location of the printer connector, see “parallel connector”
on page 5.)
If the preceding items are correct and the printer still does not work, run the
tests described in the printer manual. If the tests show that the printer is OK,
have the computer serviced.
Problem Action
The computer has an
intermittent problem.
An intermittent problem can be difficult to find.
Check that all cables and cords are securely connected to the rear of the
computer and to the attached options.
If the problem occurs only when the computer is powered by a battery pack,
replace the battery pack with a fully charged one.
If the preceding items are correct and there is still a problem, make a note of
the problem and what the computer was doing when the problem occurred.
Then contact your IBM authorized reseller or IBM marketing representative for
help.
