General printer issues The printer will not start If the printer will not start (the front panel is blank or the diagnostic LEDs are all off), you are recommended to replace the firmware, in the following way. 1. Go to the Knowledge Center (see Knowledge Center on page 190) and download the firmware. 2. Save the firmware on a USB flash drive. Ideally, the USB flash drive should be empty and formatted with the FAT filesystem. 3. Ensure that the printer is turned off. Connect the USB flash drive to the Hi-Speed USB host port beside the front panel, then turn the printer on. 4. The printer takes about a minute to read the firmware file, then asks you to remove the USB flash drive. 5. The printer automatically installs the new firmware and restarts. 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. ● Nesting may be on (T1300 series only) and the printer is waiting for the specified nest wait time before calculating the appropriate nests. In this case, the front panel shows the remaining time needed for nesting. ● You may have the wrong graphic language setting, see Change the graphic language setting on page 33. ● 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 or (T1300 series only) accounting information, see Job status messages on page 73. ● You may have requested a print preview (T1300 series only) from your printer driver. This is a function you can use to check that the image is the one you want. In this case, the preview is displayed on your screen, and you must click the Print button to start printing. ● If you are using Mac OS with a USB connection, you may find that you need to change the data encoding (PostScript printers only). Press , then , then Setup > Printing preferences > PS > Select encoding > ASCII. Then configure your application to send ASCII data. 180 Chapter 18 Troubleshooting general printer issues ENWW
