3.1.3 Prevention of ink soiling
Be careful when handling the BJ ink cartridge nozzle, head cap,
head wiper and waste ink pad. Residual ink may soil the main unit,
working surfaces, your hands and clothes, etc.
The ink is water-soluble, but because it contains pigments, it will not wash out of clothes.
The ink does not contain any substances that are harmful to humans,
but does contain organic solvents (isopropyl alcohol 67-63-0, glycerin 56-81-5 and ethylene glycol 107-21-1).
If the ink should accidentally get into someone’s eyes, rinse the affected eye
with plenty of clean water and seek medical attention.
If a large quantity of ink is accidentally swallowed, seek medical advice immediately.
In such a case, let the doctor know exactly what is written on the BJ cartridge label.
Conductivity of the ink
The ink used in the BJ cartridge is conductive. This means that, if the ink leaks, mechanical parts should be
wiped with a dampened paper towel or similar and electrical circuits wiped with tissue paper so that all ink is
removed from below the IC chips.
If power is switched on while ink is leaking on the electrical circuits, the circuitry may short out and be damaged.
If ink is leaking, the power must be switched off.
