Measure the curl of the paper.

Type of curl
Face curl: The set paper is warped upward.
Back curl: The set paper is warped downward.
Measurement of curl
Load one sheet of paper on a flat surface, apply the scale to the leading edge of the paper, and measure the curl at the four edges. The maximum value is the curl value.

Curl standard

Acceptable curl amount varies depending on the basic weight of the paper.

Paper weight	Curl amount
Paper Weight 0 - 6	Face curl: 10 mm Back curl: 10 mm
Paper Weight 7	Face curl: 10 mm Back curl: 5 mm
Paper Weight 8	Face curl: 10 mm Back curl: 3 mm
Paper Weight 9	Face curl: 10 mm Back curl: 0 mm

Is the paper curl within the curl standard?

Yes	Proceed to Step 6.
No	Go to the next step.

Place the curled surface down on a flat surface.

Hold the end of the paper and straighten it in the opposite direction to the curl direction so that the paper is rounded.

Is the problem resolved?

Yes	Finished!
No	Go to the next step.

Remove the paper, loosen it, and reset it.

Is the problem resolved?

Yes	Finished!
No	Go to the next step.

In the [Finishing: Interposer] group on [Adjustment Settings for Operators], select 1103: [Interposer Fan Level] and check the set value of [Interposer Upper Tray] or [Interposer Lower Tray]. Is it set to "0 %"?

Yes	Go to the next step.
No	Set the value to "0".

Is the problem resolved?

Yes	Finished!
No	Go to the next step.

In the [Finishing: Interposer] group on [Adjustment Settings for Operators], select 1103: [Interposer Fan Level] to adjust the correction value of [Interposer Upper Tray] or [Interposer Lower Tray].

Refer to the following table to determine the correction value from the initial value and the recommended correction value.

	Weight 1	Weight 2	Weight 3	Weight 4	Weight 5	Weight 6	Weight 7	Weight 8
	52.3 – 63.0 g/m²	63.1 – 80.0 g/m²	80.1 – 105.0 g/m²	105.1 – 163.0 g/m²	163.1 – 220.0 g/m²	220.1 – 256.0 g/m²	256.1 – 300.0 g/m²	300.1 – 350.0 g/m²
Initial value	10 %^*1	10 %^*1	30 %^*1	30 %^*1	50 %	50 %	80 %	80 %
Recommended correction value	10 % – 30 %	10 % – 30 %	10 % – 30 %	10 % – 30 %	10 % – 30 %	10 % – 30 %	10 % – 20 %	10 % – 20%

*1 The fan operates when using coated paper. The fan also starts when the correction value is entered.

Set the correction value to 0 % to 10 %.

Is the problem resolved?

Yes	Finished! After printing, set the correction value to "0 %".
No	Go to the next step.

Set the correction value to 10 % to 30 %.

Is the problem resolved?

Yes	Finished! After printing, set the correction value to "0 %".
No	Contact your service representative.
