Tips on How to Use Your Machine Page 76 of 707 pages Tip!: Carefully choose the area to place the machine! Place the machine at least 5.91 inches / 15 cm away from other electrical appliances such as fluorescent lamps. If the machine is placed closer to those, it may not be able to work properly due to fluorescent noises. How to maintain the optimal printing quality? The key to printing with the optimal printing quality is to prevent the Print Head from drying or clogging. Always follow the following steps for optimal printing quality. Follow the procedure below to disconnect the power plug. 1. Press the ON button on the machine to turn it off. 2. Make sure that the POWER lamp is not lit. 3. Disconnect the power plug from the wall outlet. If you press the ON button to turn off the power, the machine caps the Print Head (nozzles) automatically to prevent from drying. If you disconnect the power plug from the wall outlet before the POWER lamp is turned off, the Print Head will not be capped properly and this will cause drying or clogging. To disconnect the power plug, be sure to follow this procedure. Print periodically! Just as the tip of a felt pen becomes dry and unusable if it has not been used for a long time, even if it is capped, the Print Head too, may become dried or clogged if the machine has not been used for a long time. We recommend you to use the machine at least once a month. Note Depending on the type of paper, ink may blur if you trace the printed area with a highlight pen or paint-stick, or bleed if water or sweat comes in contact with the printed area. Colors are uneven, and print results are blurred. Tip!: Print the nozzle check pattern to check if the nozzles are clogged. If the print head nozzles are clogged, colors may become uneven or the print results may be blurred.
