Replacing air filter element in the electronic chamber ventilation system
The air filter element in the electronic chamber should be replaced after the equipment has
worked 1000 hours, at the same time when the main ink filter and gun filter are replaced.
However, this time interval can be shortened if the printer works in a polluted (dusty)
environment. In such an environment, the condition of the element should be checked
regularly and the element replaced, if need be. The condition of the element can be assessed
by checking the level of pollution of the air inlet at the bottom of the electronic chamber door
(under the fan). When the air inlet is highly polluted, the filter element needs replacing. The
