3. If the present value is High, select Middle. If it is Middle, select Low.
4. Print the image and check toner fusion. Is the problem resolved?
If the problem persists, the machine may be faulty or the paper unsupported. Contact your
service representative. The problem requires further investigation, so consult the product
specialist.
Improving Print Quality with Mixed Paper
This section explains how to give priority to print quality over production when using different types and
thicknesses of paper in the same print jobs.
In order to ensure optimum toner fusing for different paper types and thicknesses, the
operation of the fusing unit can be adjusted for the paper conditions. These settings ensure
productivity when different paper is used continuously, but problems such as glossy lines can
occur when different paper is used in the same job.
There will be occasions when quality must take precedence over productivity, depending on
how the operators are using the machine. In such a case, the Image Quality Priority Mode can
be used.
Conditions Where Image Quality Can be Improved
There is a large difference in the heating roller temperature setting between the front and rear of
the paper area after changing the paper and paper thickness
There is a large difference in the paper width (front-to-back on paper path is the length) after
changing the paper and paper thickness
There is repetition of low volume print jobs
Solution
1. On the Adjustment Settings for Skilled Operators menu, select Machine: Quality Adjust >
Production Priority Mode > Production Priority > change the setting from “Normal” to “Priority”.
