12.4.2 Fusing Temperature
A. Use
• To adjust individually the temperature of the heating roller and the fusing pressure roller
for each type of paper, thereby coping with varying fusing performance under changing
environmental conditions.
• When fusing performance is poor, or wax streak or offset occurs when the type of paper
is changed or environmental conditions change.
• Use when the curling of the paper due to the paper type or environmental change
occurred, or when the paper jam, as well as stapling or folding position error occurred
due to the curling of the paper.
• By setting the temperature higher (+), gloss of print can be improved.
• By setting the temperature lower (-), exit roller mark can be reduced.
