The performance of this machine is affected by the environment of the
installing site. Avoid installation to the following places:

• Avoid installation in direct sunlight, otherwise the plastic parts may

be deformed.

• Avoid installation in a place of high temperature, high humidity, low

temperature or low humidity, otherwise paper may be dampened and
frost may be generated in the machine to cause a paper jam and
dirty copy.

• Avoid installation in a dusty place, otherwise dust may enter the

machine to cause dirty copy or machine troubles.

• Avoid installation to a place with much vibration, otherwise the

machine may cause troubles.

• Avoid installation to a place of poor ventilation.

• Avoid installation to a place where there is ammonium gas.

Installation near a diazo-copier may lead to dirty copy.
