Do not unplug the printer unnecessarily. The printer may clean the print head nozzles and consume a small amount of ink when

zyou plug it into an AC outlet or a power strip.

Never unplug the printer or turn off a power strip to which the printer is attached when the printer’s power is turned on. This may prevent the print head unit from returning to the home position. Once in the home position, the print head unit and the ink tanks are capped, which prevents them from damage or drying out. This is critical. If left uncapped, the print head unit may clog and may need to be replaced.

For reliable data communications between your computer and the printer, use a short cable, six feet or less in length. The cable must be bi-directional.

Do not move the mechanism that holds the print head unit and ink tanks. Attempting to move the carriage may damage delicate mechanical parts.

Do not touch the print head nozzles on the print head unit. Ink may leak out and cause stains. Also, you may permanently damage your print head unit, which would require you to

zpurchase a replacement.

Do not touch the white padding inside the ink tank. Ink may leak
