HP 0706124 REV B manual Relative Humidity Printer Action

Dryer Operation As the printed output advances past the dryer outlets, the dryer blows air over the output to dry it. The print will continue to advance until the trailing edge of the print has passed under the dryer. The print remains stationary for twenty seconds, then will reverse or advance according to the supply loop option selected (see page 2-14). To cancel the twenty-second delay, press the ￿ (Cancel) key.

The printer’s relative humidity sensor enables the printer to adjust the media advance speed to ensure adequate drying. Higher relative humidity will result in slower printing. You can customize this feature from the control panel; for instructions, see page 2-12.
