Printer Problems
Basic Checks:
•Check the diagnostic lights to see if the specific problem is identified.
•Disconnect the cable from the computer and check the cable
connector for bent or broken pins. Check for damaged or frayed cables.
•If the cable is not damaged, ensure that it is firmly connected to the
computer.
•Test the electrical outlet: ensure that the electrical outlet is working by
testing it with a different device such as a lamp.
•Ensure that the printer is turned on.
•Check for interference: electrical appliances on the same circuit or
operating in close proximity to the computer can cause interference.
