Maintaining When Not Using for a Long Period of Time If the printer will not be used for a long time, turn its power off, disconnect the USB cable, and then unplug the power cable from the wall outlet. Be careful of the following: z The nozzles of the print-heads may dry out and become clogged. To prevent this, periodically print something. Even if you do not print anything, turn the printer on for a few minutes once a month. z If you do not use the printer for a long period of time, always check if the nozzles are clogged by printing a nozzle check test pattern. Clean the print-heads as necessary, and then begin printing. z If you do not use the printer at least for 8 hours, printing may not be performed normally even if head cleaning is performed multiple times. If this happens, turn the power off and leave the printer alone for a while. Then, turn the power on again and perform the nozzle check and head cleaning. z After head cleaning is performed multiple times, clogged ink will dissolve over time, and normal printing may become possible. z If there is no improvement after performing the steps above, contact sales or service representative. z p.119 "Where to Inquire" z p.68 "Nozzle Check" z p.69 "Head-cleaning" 127
