c. Overheating of the Ends
In a low-temperature environment (machine temperature of lower than 12°C), an error can
occur as a result of overheating of the edges (as when small-size paper is used) while copy-
ing temperature is controlled to 212°C and the temperature of the fixing upper roller is 75°C
for a period of 60 min from power-on.
If continuous printing is performed for 3 min or more, printing temperature is switched
from 212°C to 205°C to prevent overheating.
d. Jam Recovery Mode
The sequence used after jam removal differs depending on the following conditions:
1. If paper exists in the fixing/feeding assembly,
The fixing heater will be turned off in response to a jam, and post-jam removal initial
multiple rotation will be excluded.
2. If no paper exists in the fixing/feeding assembly,
The temperature control mechanism is turned on without turning off the fixing heater,
and the machine will be ready for printing immediately after jam removal.
e. Power Save Mode
A press on the Power Save key on the control panel causes the machine to decrease the
control temperature used in standby, thus reducing power consumption. The mode may be
changed as follows in user mode:

*Period of time before the machine starts standby state in response to a second press on
the Power Save key.
