Beeper and Fans

The beeper contains built-in driver circuitry so that it beeps under firm- ware control. The beeper alerts the user to error conditions.

There exists three types of fans that can be on these printers.

A single fan, located below the power supply, is used for cooling the power supply. Air blows over the power supply and the heated air is forced out the back of the printer. It also blows air on the temperature and humidity sensors so they can measure ambient conditions more accurately.

A fan is located inside the platen with its fan vent seen from under the platen on the right side of the printer. This fan provides suction on the platen bed and holds the paper (media) flat during the printing process. The 60 inch model has an additional suction fan located near the center of the printer inside the platen.

Two fans are located inside the dryer plenum body to draw ambient air inside to be heated. These fans are tested when power is applied to the printer.
