2.2.2 Ink mist
The BJ cartridge ejects ink onto the paper during printing. After the printer is used for
a long period or used heavily, the ink mist bouncing back from the paper could
accumulate and soil the front cover, platen, and the area around the operation panel,
purge unit, and paper output tray.
Carefully wipe off the ink mist with a soft dampened cloth so that hands or clothing
will not be stained by soiled parts during servicing.
Also, be careful not to smudge the pick roller when removing the upper cover.
2.2.3 Precautions for damage due to static electricity
Static electricity can be generated by clothing rubbing against each other and may
accumulate in the body. If you touch electrical elements, the discharge of static
electricity could damage them, or change their electrical characteristics. For this
reason, avoid touching the ink sensor contacts or the printer's BJ cartridge contacts.
