c) Preventing ink clogging
Do not touch the ink cartridge’s ink outlets.  Doing so may introduce foreign matter into
the printing head’s joint pipes, causing poor ink suction.  After removing the cap from the
ink cartridge, immediately install the ink cartridge in the printing head to prevent the ink
at the nozzles from drying out and clogging.  Do not remove the ink cartridge except when
it is to be replaced.
If the ink nozzles are clogged or if the ink suction is poor, the printout may
have horizontal white stripes.  If the cleaning operation does not restore it
to normal, replace the BJ cartridge.
