The correct answer is: A. Make sure the printer is on line.
If the power lamp is on, but the printer will not print, the first thing you should do is make sure that the printer is actually on line. This means that the printer is plugged into an outlet that is turned on, and that the printer is turned on itself.
If the printer is on line and still will not print, you can try the following:
- Check to see if there is paper in the printer.
- Make sure that the printer is not in error mode.
- Try printing a test page.
- If all else fails, you may need to call a technician to service the printer.
Option B, replace the AC line fuse, is only necessary if the power lamp is not on. If the power lamp is on, then the AC line fuse is not the problem.
Option C, turn the printer on and off, is a good troubleshooting step, but it is not the only thing you should do if the printer will not print.
Option D, replace the ribbon, is only necessary if the printer is a dot-matrix printer. Most printers today do not use ribbons.
Option E, none of the above, is not the correct answer.
