Ink system issues When the front panel displays a warning message that the clean process is needed, you are recommended to clean the printhead drop detector. If you do not clean the printhead drop detector immediately, the printer continues working normally, however, the front panel display continues to show the warning. CAUTION: Wear gloves to avoid getting ink on your hands. 1. Turn off the printer at the front panel. 2. To avoid an electric shock, switch the printer off and unplug it. 3. Open the window. 170 Chapter 16 Troubleshooting ink cartridge and printhead issues ENWW
