detected properly. To prevent this, checkup and cleaning
should be carried out periodically.

NOTE: When using the liquid leak sensor, follow the
instructions given below.
(a) Before using a solvent, the leak sensor
function should be activated.

fail to work for leak in a very small amount.
The function may also fail to work for a
solvent having a high volatility.
Always check for liquid leak so as to
circumvent a serious situation even when the
leak sensor function is activated.
