Solution

Make sure the printer’s power switch is on.

The printer might be in Power Save mode. Press [Go] .

Make sure all power cables are securely attached and plugged into a grounded power source.

Press [Go] .

Either no cable, a bad cable, or only a LocalTalk cable is attached to the

HP JetDirect internal print server.

For LocalTalk connections, the message should disappear after approximately 5 minutes, during which normal printing is possible. Check the cable connection.

The HP JetDirect internal print server might be improperly installed.

Reinstall the print server.

There might be a network problem. See the HP JetDirect Print Server

Software Installation Guide. Also, see “Step 4: Connecting the Printer to a Network” about how to add 50-Ohm terminators, if necessary.

Cannot print from the computer using a parallel cable.

The cable might be installed incorrectly, too long, or faulty. Remove the cable and reconnect it, making sure it is securely connected. Try another parallel cable under 10 feet (approximately 3 meters) in length. Replace the cable with an HP parallel cable (part number C2946A) or equivalent.

The wrong port might be selected or rerouted. Check the MODE statement in the AUTOEXEC.BAT file. In Windows 3.1, look in the

Control Panel to see which port is selected. In Windows 95 or Windows

NT, check the Parallel Port Capture.

Cannot print using a sharing device.

Random “garbage” characters are printing.

There might be a bad port on the computer or printer. Try using a different port or, if possible, a different computer or printer to isolate the problem.

Try to isolate the cause of the problem. Test the printer using a cable connected directly from the computer to the printer. Contact the sharing device vendor for troubleshooting steps.

The interface cable might be bad or loose. Check the cable and connection. Try another parallel cable under 10 feet (approximately 3 meters) in length. Replace the cable with an HP Parallel cable (part number C2946A) or equivalent.

Printer control panel displays

CLEAR PAPER JAM .

Printer control panel displays an unfamiliar message.

Media might be jammed in one of several locations. Clear all jams according to instructions in the quick reference guide.

Turn the printer off, then back on. If the message does not clear, see the online user’s guide for more information.
