Solving general problems If the MFP is not responding properly, complete the steps in the following checklist, in order. If the printer does not pass a step, follow the corresponding troubleshooting suggestions. If a step resolves the problem, you can stop without performing the other steps on the checklist. Troubleshooting checklist 1. Make sure the MFP Ready light is on. If no lights are on, complete these steps: a. Check the power-cable connections. b. Check that the power switch is on. c. Check the power source by plugging the MFP directly into the wall or into a different outlet. d. If none of these measures restores power, contact HP Customer Care. (See HP customer care or the support flyer that came in the printer box.) 2. Check the cabling. a. Check the cable connection between the MFP and the computer or network port. Make sure that the connection is secure. b. Make sure that the cable itself is not faulty by using a different cable, if possible. c. Check the network connection. See Solving network connectivity problems. 3. Ensure that the print media that you are using meets specifications. See Print media specifications. 4. Print a configuration page (see Configuration page. If the MFP is connected to a network, an HP Jetdirect page also prints. a. If the pages do not print, check that at least one tray contains print media. b. If the page jams in the MFP, see Clearing jams. 5. If the configuration page prints, check the following items. a. If the page prints correctly, then the printer hardware is working. The problem is with the computer you are using, with the printer driver, or with the program. b. If the page does not print correctly, the problem is with the MFP hardware. Contact HP Customer Care. (See HP customer care or the support flyer that came in the printer box.) 6. At the computer, check to see if the print queue is stopped, paused, or set to print offline. a. Windows: Click Start, click Settings, and then click Printers or Printers and Faxes. Double-click HP LaserJet 4345mfp. b. Mac OS 9: Double-click the HP LaserJet 4345mfp icon on the desktop. c.

Verify that you have installed the HP LaserJet 4345mfp Series printer driver. Check the program to make sure that you are using an HP LaserJet 4345mfp Series printer driver. 8.
