Efficient Use Of The Dryer; Direction Of Warm Air; Airflow Setting - HP Designjet 10000s User Manual

CAUTION Do not sit on the dryer or lean heavily on it. It is not strong enough to support your
weight.
Do not turn off the main power switch until the fan has finished its three-minute cooling-off
period after the heater stops. When the main power switch is turned off, the fan stops turning,
resulting in an increase in internal temperatures due to the remaining heat of the heater. This
may damage the dryer. In addition heated surface may cause burns. If the main power switch
is accidentally turned off, or the power cable pulled out, turn on the power again and run the
fan with the air flow set to high for at least five minutes to cool down the dryer.
If the power cable is accidentally disconnected, do not touch the dryer, which will still be hot.
The ink does not dry immediately. Take care that freshly-printed paper does not touch anything.
The printed paper may be damaged if the dryer is too close to it. Make sure the dryer is at
least 50 mm from the paper.
If the dryer's air inlet becomes clogged with dust, the internal temperature will rise, which may
cause a failure. Clean the air inlet at regular intervals.

Efficient use of the dryer

Direction of warm air

Set the body of the dryer pointing slightly downward as shown below. Drying efficiency increases with
warm air blowing along the surface of the paper.
1. Paper
2. Dryer
3. Warm air

Airflow setting

Air flow can be set to one of three levels. The dryer uses a constant conduction heater, and accordingly
temperature drops as air flow increases, or rises as air flow decreases. To improve the drying efficiency,
high air flow (H) is recommended during warm air operation.
