Introduction Turn the power off Turn off the printer WARNING! The printer has an internal clock which allows it to wash the printheads automatically, flushing some ink through the printhead, which keeps the printheads in good condition. This is done after the first 20 hours without printing and every 3 days. If the printer is switched off for a long period, this process does not happen. If the ink does not flow through the printheads from time to time, the ink will dry inside the nozzles, reaching a point where it is impossible to recover them and the printhead will fail. This will mean an expensive printhead replacement. The printer power switch on the rear of the printer should be used only when the printer is turned off to move it, to connect it to a computer, or to install or maintain printer parts. CAUTION If you need to leave the printer unattended for any reason, ensure that the printer is on, the ink cartridges are full, and the waste ink bottle is empty, so that automatic maintenance (performed after the first 20 hours without printing and every 3 days) can be completed successfully for the time you are not present. If needed, install new ink cartridges. The ink cartridges that you replace can be reused when you return them to your printer, if they still contain ink. WARNING! Turn the printer off and unplug the power cable from the power outlet in any of the following cases; when placing your hands inside the printer, if there is smoke or an unusual smell coming from the printer, if the printer is making an unusual noise not heard during normal operation, a piece of metal or a liquid (not part of cleaning and maintenance routines) touches internal parts of the printer, during an electrical (thunder/lightning) storm, during a power failure. CAUTION Always hold the power cord by the plug when connecting and disconnecting it from the power outlet. Never pull on the cord because this may damage it and create risk of fire and electric shock. Turn off the power by pressing the power on/off key on the front panel for a couple of seconds. The front panel displays the message above to indicate that a shutdown process is in progress. After the process ends, the power is turned off. If you intend to turn the printer off for a short time, you can avoid the printhead wash operation by pressing the power on/off key while pressing the Cancel key. The printhead wash operation is always recommended. ENWW Turn the power on/off 17
