Insufficient Toner Fusing

This section explains how to resolve the problem of insufficient toner fusing.
To adjust the following settings, register beforehand the type of paper that you are using as a

custom paper.
Changing the fusing temperature or changing the process speed may produce one or more of

the following side effects:
 Paper curling
Paper misfeeding

 Blisters
Glossy lines

Change of gloss

 If one or more of the above side effects occur, adjust by decreasing the fusing temperature or
the process speed.
Solution:
Carry out in the order of (a) followed by (b), stopping when the problem is resolved.
(a) Changing the fusing temperature
1. In Advanced Settings for the custom paper in use, select Fusing Heat Roller Temperature Adj and
increase the temperature by 5°C.
2. Print the image and check toner fusion. Is the problem resolved?
Yes Finished.
No Increase the temperature an additional 5 °C.
3. Repeat Step 2 until the temperature reaches 185 °C. Is the problem resolved?
Yes
No
4. Check the type of your machine. Is it Pro 8300S?
Yes
No
(b): Changing the process speed
This procedure is available only for Pro 8320S/Pro 8320 and Pro 8310S/Pro 8310.
Reducing the speed will slow down printing to give the toner more time to fuse. However, as a result,
throughput will be reduced.
For example, when printing on A4/LT paper:
Pro 8320S/Pro 8320
If the process speed is changed from High to Middle: 136 cpm drops to 111 cpm

If the process speed is changed from Middle to Low: 111 cpm drops to 96 cpm

688
Finished.
Go to the next step.
Consult the product specialist.
Perform Procedure (b) below.
