The parts and configuration of the fusing unit (shown in cross-section above) are the same as those of the
previous machine. However, there are some improvements:
• Warm-up time is shorter.
• Longer service lives for some parts.
• Some parts have been discarded, and four parts have been replaced.
• The following four service parts for the D014/D015 and D081/D082 fusing unit are not the
same; they cannot be substituted for one another when servicing these machines: 1) Hot roller,
2) Pressure roller, 3) Pressure roller bearing, 4) Oil supply roller.
• For more details, see "Fusing Unit" in the "Replacement and Adjustments" section.
Shorter Warm-up Time (New WUT)
Model WUT: Old to New Faster By:
D081 NA 90 s to 70 s 20 s
D081 EU, D082 75 s to 60 s 15 s
The thickness of the metal core in the hot roller has been reduced from 1.5 mm to 1.0 mm. This allows the
core to reach the ready temperature much faster. The rotational speed of the hot roller during warm-up
has been increased from 141 mm/s to 282 mm/s. Also, the ready temperature (re-load temperature) has
been raised from 20°C to 40°C (68°F to 104°F).
Longer Service Lives
Part Old Service Life New Service Life Extended
Hot roller 300 K 450 K 150 K
Cleaning unit 300 K 450 K 150 K
Pressure bearing 600 K 1200 K 600 K
• The hot roller is composed of new, low cost material of greater durability.
• The new cleaning unit uses more oil, supplies less oil, and has a new oil application roller.
• The curvature of the pressure bearing has been reduced and new rubber seals keep out foreign matter.
