Solution:

Carry out the following sequence of procedures. Terminate the sequence as soon as the problem is resolved.

Procedure 1: Adjust the image transfer current

Measure by a ruler or other device the length (in mm) of the area from the leading edge of the paper where the paper is affected by thick density, insufficient density, toner blasting, or streaks.

In [Advanced Settings] for the custom paper, check the present value of the current for the image transfer roller.

<Printing in black and white>

Select 022: [Image Transfer Current: B&W].

<Printing in full color>

Select 023: [Image Transfer Current: FC: Black].

Is it set to 150 A?

Yes	Proceed to "Procedure 2: Adjust the transferability at the paper transfer unit".
No	Go to the next step.

Increase the value in 022: [Image Transfer Current: B&W] or 023: [Image Transfer Current: FC: Black] by 5 A.

Print the image. Has the problem been resolved?

Yes	Finished!
No	Go to the next step.

Specify the area to apply the image transfer current at the leading edge of the paper.

In 028: [Image Trnsf Currnt; Lead Edg Dist: B&W] or 030: [Image Trnsf Currnt; Lead Edg Dist: FC: K], enter the value which is 5 mm higher than the value measured in Step 1.

Print the image. Has the problem been resolved?

Yes	Finished!
No	Repeat Steps 4 and 5. If the problem persists even though you have increased the value to 150 A, proceed to "Procedure 2: Adjust the transferability at the paper transfer unit".

Procedure 2: Adjust the transferability at the paper transfer unit

In [Advanced Settings] for the custom paper, set 087: [Paper Transfer High Pressure Mode] to [High].

Print the image. Has the problem been resolved?

Yes	Finished!
No	Go to the next step.

Increase the value in 084: [Adjust Gap of Paper Transfer] by 1 step.

If [Off] is selected, change the value to [Small Gap]. If [Small Gap] is selected, change the value to [Medium Gap]. If [Medium Gap] is selected, change the value to [Large Gap].

Print the image. Has the problem been resolved?

Yes	Finished!
No	Decrease the value in 087: [Paper Transfer High Pressure Mode] by 1 step. If [High] is selected, change the value to [Standard]. If [Standard] is selected, change the value to [Low]. If [Low] is selected, change the value to [Off].

Print the image. Has the problem been resolved?

Yes	Finished!
No	Repeat Steps 3 to 5. If the problem persists even though you have set 084: [Adjust Gap of Paper Transfer] to [Large Gap], contact your service representative.
