Troubleshooting System Components
The printing system is composed of four basic components: printer,
computer, power source, and communications. Any one of these
components can prevent the printer from functioning properly.
Verifying the Printer Components
Power Source Verification
Start by verifying that power is available at the printer. Visually inspect
the control panel to verify that the power indicator (green LED) is lit. If
it is not, press the Set Page button and note if the power indicator lights
up. If it does, the power system is all right. If it does not, press the printer
reset button. If the power indicator still does not light, check the power
cable, by connecting it to a different printer. If the power indicator works
on the new printer, then the cable is all right, and the printer that was
originally connected is suspect. If it does not light, then the problem is
most likely the cable or the power source. Depending on the results,
either replace the cable or return the printer for service.
