13. Dispose of the soiled sponge in a safe place to prevent the transfer of ink onto hands and clothing. If the front panel continues to show the Reseat or Replace message, replace the printhead or call your service representative. Clean the exterior of the printer Use a damp sponge or a soft cloth and a mild household cleaner such as non-abrasive liquid soap to clean the outside of the printer and all other parts of the printer that you regularly touch as part of normal operation (for example, ink cartridge drawer handles). There may be some dampness from condensation under the fans of the curing module, which should be wiped with a dry cloth. WARNING! To avoid an electric shock, make sure that the printer is turned OFF and unplugged before you clean it. Do not let water get inside the printer. CAUTION: Do not use abrasive cleaners on the printer. Clean the platen You should clean your printer's platen every few months, or when necessary. NOTE: If you print on wide substrate after having printed on narrower substrate, you may find that the left side of the platen has become dirty. If this contaminated section of the platen is not cleaned, it could leave marks on the back of the substrate. CAUTION: Be careful not to damage the substrate-advance sensor when cleaning the platen. The sensor is the very small rectangular window (less than 1 cm²) found close to the third pinchwheel from the right. See Clean the substrate-advance sensor window on page 18. Follow these instructions to clean the platen. 1. Unload all substrate from the printer. See the User's guide. 2. Turn off the printer and wait until it has cooled down, then unlock and open the printer window. Maintain hardware ENWW Clean the exterior of the printer 15
