Keeping Print Quality High The key to maintaining optimal print quality is preventing the print head from drying out or becoming clogged. To ensure print quality, follow these tips. Note • On some paper, ink may run if you mark over it with a highlighter or water-based marker, or if water or sweat comes into contact with printed areas. Never unplug the machine until it is off Pressing the ON button to turn off the machine will automatically cap the print head (which is equipped with nozzles) to prevent it from drying out. However, capping is not performed if you unplug the machine while the POWER lamp is lit or flashing. This may cause drying or clogging. Before unplugging the machine, make sure the POWER lamp is not lit. Important • Unplugging the machine will erase all documents in the machine's memory. Send faxes, print documents, or save jobs to a USB flash drive as needed before unplugging the machine. Print regularly Just as felt-tip pens dry up and become unusable (even when capped) if not used over extended periods, the print head may dry out or become clogged if the machine is not used for some time. Use the machine at least once a month, if possible. Allow regular ink mixing The machine automatically mixes ink periodically to maintain optimal print quality. Regular printing helps keep the ink in good condition. If the machine is not used for some time, it will automatically mix the ink before printing. 422
