HP Printers and others have a lot of little basic bugs, but if you know how to deal with some of the more habitual problems you will make the printer your friendly companion to your tasks and projects.
Error code 55 Problem: “Internal Communication Problem" error message
Possible Causes and Solutions:
On IIISi/4Si Printers this is due to the DC controller not receiving the proper information upon startup. Check the connectors on the DC controller and power supply. If you don't hear the motor immediately and you don't have a paper jam, change the power supply
• Windows XP, click Start and then click Control Panel. Click Printers And Other Hardware and Printers And Faxes. In the Printers And Faxes window, from the File menu, click Server Properties, then click the Drivers tab. This shows the settings in your printer's driver. Compare the settings in this dialog box with the ideal settings in your printer's manual. If you see a discrepancy in these settings, the printer may simply need a new driver. Delete old driver first. You can download or update printer drivers from the printer manufacturer's Web site.
