Poor Fusing on the First Few Copies
If the room is cold, the hot roller may not stay hot
for very long after reaching the print ready
temperature.
To solve this problem, set SP 1103 to 'on'.

More on Poor Fusing on the First Few Copies
If the room is cold, the fusing on the first few copies may be poor because the
hot roller may not be holding enough heat, even if it has reached the correct
fusing temperature.
If this happens, enable fusing idling with SP 1103. This will turn the hot roller and
heat it for longer than is needed to heat the roller to the ready temperature (it
turns for 30 seconds instead of just 6 seconds, if the fusing unit temperature is
lower than 100°C). The customer must wait this extra time whenever the
machine is switched on or recovers from energy saver mode.
With fusing idling set to 'off', the machine just waits for the roller to reach the
ready temperature, then prints. This may not be enough to warm the roller up.
What is the purpose of fusing idling?
Fusing idling allows the hot roller to heat the pressure roller to a constant
temperature. This prevents insufficient fusing opposite cooler parts of the
pressure roller. It also repairs small dents on the pressure roller that could cause
jitter on the first few copies. However, the machine takes longer to warm up, so it
is normally only used in high-speed copiers.
Fusing idling is normally disabled in this machine, because the copy speed is
only in the middle range. However, if fusing is incomplete on the 1st and 2nd
copies, switch it on. This may occur if the room is cold, especially with thick
paper.
