Do not unplug the printer unnecessarily. The printer may clean
the print head nozzles and consume a small amount of ink when
you plug it into an AC outlet or a power strip.
z
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.
z
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.
z
Do not move the mechanism that holds the print head unit and ink
tanks. Attempting to move the carriage may damage delicate
mechanical parts.
z
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
purchase a replacement.
z
Do not touch the white padding inside the ink tank. Ink may leak
out and you may damage the tank.
