Fusing Temperature Control and Machine Status - Overview
Fusing temperature control operates differently depending on the status of the
machine:
• At power on (cold/warm starts)
• During standby
• During machine operation (low limit, paper sizes)
• Low power mode (during and immediately after)
• In Energy Saver mode
Fusing control in each operation mode is described below.
NOTE:
• In the descriptions below, the "1", "2", "3" notations refer to the fusing lamp
number (6.16.4 - Overview).
Fusing Temperature Control at Power On (Cold/Warm Starts)
1. After the machine power is turned off/on
If the fusing unit temperature is below the temperature set with SP1105 010,
three fusing lamps switch on in this order: 3 Æ 2 Æ 1.
-or-
If the fusing temperature is above the temperature set with SP1105 010, two
lamps (2 and 3) switch on in this order: 3 Æ 2

2. When the temperature rises to the temperature set with SP1105 010, fusing
lamp 1 switches off.
3. When the temperature reaches the standby temperature, fusing lamps 3 and 2
switch off in this order: 3 Æ 2
