Part 2: MAINTENANCE

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.

Upper Cover

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.
