The printer does not print If all is in order (paper loaded, all ink components installed and no file errors), there are still reasons why a file you have sent from your computer may not start printing when expected: ● You may have an electrical power problem. If there is no activity at all from the printer, and the front panel does not respond, check that the power cable is connected correctly and that there is power available at the socket. ● You may be experiencing unusual electromagnetic phenomena, such as strong electromagnetic fields or severe electrical disturbances, which can cause the printer to behave strangely or even stop working. In this case, turn off the printer using the Power key on the front panel and unplug the power cord, wait until the electromagnetic environment has returned to normal, then turn it on again. If you still experience problems, please contact your customer service representative. ● You may have the wrong graphic language setting, see Change the graphic language setting on page 21. ● You may not have installed in your computer the correct driver for your printer, see the Assembly instructions. ● If you are printing on a sheet, you must specify Manual Feed as the paper source in your printer driver. ● The printer may be holding the job for paper. The printer seems slow Here are some possible explanations. ● Did you set the print-quality to Best or Max Detail? Best-quality and maximum detail prints take longer. ● Did you specify the correct paper type when loading the paper? Some paper types require more time for printing, for example, photo and coated papers require more drying time between passes. To find out the printer's current paper type setting, see View information about the paper on page 40. ● Do you have a network connection to your printer? Check that all components used in the network (network interface cards, hubs, routers, switches, cables) are capable of high-speed operation. Is there a lot of traffic from other devices on the network? ● Did you specify Extended drying time in the front panel? Try changing the drying time to Optimal. Communication failures between computer and printer Some symptoms are: ● The front-panel display does not show the Receiving message when you have sent an image to the printer. ● Your computer displays an error message when you are trying to print. ● Your computer or printer hangs (stays idle), while communication is taking place. ● Your printed output shows random or inexplicable errors (misplaced lines, partial graphics etc.) General printer issues 146 Chapter 15 Troubleshooting general printer issues ENWW
