3. 9. 3. Adjustment of fuser inlet guide
Check the gap between the fuser inlet guide and the press roller when the following troubles
occur:
• Stain on the paper back side
• Jam at the fuser entrance
• Paper wrinkling
(1) Move the screw fastening position of the inlet
guide towards the oblong hole, and adjust with
reference to the scale.
(2) Adjust the gap between the fuse inlet guide and
the pressure roller. (0.4 <
= gap < 1.7)
3. 9. 2. Setting of fuser roller temperature
The fuser has been set (heat roller surface temperature: 200°C, pressurizing pressure: 100 kg)
taking the fusing performance, wrinkling, curling and toner transfer deficiency at the leading/
trailing edges of the duplex print into consideration when our company recommended paper is
used. This is to allow the characteristics of the paper to be demonstrated in a well-balanced
manner. However, various types of paper are used in the field, and factors such as the paper
thickness and smoothness greatly effect the fusing performance, in particular. If the fusing
performance deteriorates while using a specific type of paper, deal with that by changing the fuser
roller temperature at the setting mode “08”.
Change the heat roller setting temperature in the setting mode (08-410, 411, 883). The default is “8” (200°C),
and can be changed within the range “8” to “10” (200°C to 206°C). Input the same value in 08-410, 411 and
883.
Note: When a large value is set (to increase the temperature), the level of wrinkling, curling and toner transfer
deficiency at the leading/trailing edges of the duplex print tends to worsen.
