If you need to leave the printer turned off for a long time, follow the additional steps below. 1. Turn off the power using the Power key on the front panel. 2. Also turn off the power switch at the rear of the printer. 3. Disconnect the printer's power cable. 4. Before transporting the printer, secure the rear tray in the closed position with tape. Otherwise, the tray could open and perhaps break and fall out of the printer. CAUTION: If you turn the printer upside down, ink could escape into the printer and cause serious damage. When the printer is turned back on, it takes about three minutes to initialize itself and to check and prepare the printheads. Preparing the printheads normally takes just over a minute. However, if the printer has been off for a six weeks or more, preparing the printheads could take up to 45 minutes. CAUTION: If the printer remains off for a long period of time, the printheads may become unusable. In this case, you need to replace the printheads with new ones. TIP: Because preparing and purging the printheads uses both time and ink, you are strongly recommended to leave the printer always on or in sleep mode, whenever possible, to maintain the health of the printheads. In both cases, the printer wakes up from time to time to maintain the printheads. Thus you can avoid going through lengthy preparation processes before using your printer. Update the firmware The printer's various functions are controlled by software that resides in the printer, otherwise known as firmware. From time to time firmware updates will be available from Hewlett-Packard. These updates increase the printer's functionality and enhance its features. Firmware updates can be downloaded from the Internet and installed in your printer in the following ways; you can choose whichever you find most convenient. ● Using the HP Printer Utility under Windows, select your printer, the Support tab and then Firmware Update. ● Using the HP Printer Utility under Mac OS, select Firmware Update in the Support group. ● Using your printer's Embedded Web Server, select the Main tab and then Firmware update. NOTE: If you are using an HP Jetdirect print server to connect to a network, the HP Printer Utility will not be available, so you will need to use the Embedded Web Server. In each case, follow the instructions on your screen to download the firmware file and store it on your printer. Then select the downloaded file and click Update.
