Panel Off Mode - Gestetner B147 Service Manual

FUSING

Panel Off Mode

Entering the panel off mode
The machine enters the panel off mode under the following condition:
• The panel off timer runs out.
• The Clear Mode/Energy Saver Key is held down for one second.
If the value specified in the panel off timer is larger than the value specified in the
energy saver timer, the machine goes into the low power mode without going into
the panel off mode. A similar thing happens when the value in the panel off timer is
larger than that in the auto off timer. To make the panel off mode effective, specify
a value smaller than the values in the energy saver timer and auto off timer.
What happens in panel off mode
When the machine is in the panel off mode, each of the fusing lamps are kept at
the temperatures indicated in the table below, and the operation panel indicators
are turned off except for the Energy Saver LED and the Power LED.
If the controller receives an image print out command from an application program
(e.g. to print incoming fax data or to print data from a PC), the temperature of each
fusing lamp rises to print the data.
Return to stand-by mode
If one of the following is done, the machine returns to stand-by mode:
• The Clear Mode/Energy Saver Mode key is pressed
• Any key on the operation panel or touch panel screen is pressed
• An original is placed in the ADF
• The ADF is lifted
• A sheet of paper is placed in the by-pass feed table
The return time from the panel off mode to stand-by mode is less than 30 seconds.
