The problem is something else Chapter 15 ● Are you using the printer with the Appletalk serial port on a Macintosh computer? It is normal for the Appletalk port to be slow. Consider using the Ethertalk interface to connect your printer to your Macintosh. ● 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; see "Tell me about drying time" in the User's Guide.. ● Are your printheads in good condition? The printer may print slower to maintain print quality when a printhead is faulty. Check the printhead status in the front panel or in the Embedded Web Server, and recover or replace printheads if necessary. ● Do you have high-density black areas in your image? In this case, the printer may change temporarily to a slower print quality option in order to maintain quality. The problem is 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.) To solve a communication problem: ● Ensure that you have selected the correct printer in your software. ● Ensure that the printer works correctly when printing from other software. ● Remember that very large prints may take some time to receive, process, and print. ● If the printer is connected to a network, try using it when connected directly to your computer through a FireWire or USB cable. ● If your printer is connected to your computer through any other intermediate devices, such as switch boxes, buffer boxes, cable adapters, cable converters, etc., try using it when connected directly to your computer. ● Try another interface cable. For details of supported cables, see "Interface specifications". ● Ensure that the graphic language setting is correct. See "How do I change the graphic language setting?" on page 75. 158
