For paper other than envelopes, perform "(a) Decrease the nip width" 
"(b) Decrease the pressure roller temperature". For envelopes, perform "(a) Decrease the nip width" only. Stop the adjustment when the problem is solved.
(a) Decrease the nip width
<For paper other than envelopes>
In [Advanced Settings] for the custom paper, select 1246: [Fusing Nip Width Adjustment: Other than Envelope], and then set the value in nip width to "3".
Print the image. Has the problem been resolved?
Yes | Finished! |
No | Set the value in nip width to "2". |
Print the image. Has the problem been resolved?
Yes | Finished! |
No | Proceed to "(b) Decrease the pressure roller temperature". |
<For envelopes>
In [Advanced Settings] for the custom paper, select 1246: [Fusing Nip Width Adjustment: Other than Envelope], and then set the value in nip width to "1".
Increase the value in 1331: [Motor Speed:Fusing Belt] by 5%.
Decrease the value in 1246: [Fusing Nip Width Adjustment:Envelope] by 50 milliseconds.
Print the image. Has the problem been resolved?
Yes | Finished! |
No | 1246: Decrease the value in 1246: [Fusing Nip Width Adjustment:Envelope] by 50 milliseconds. |
Print the image. Has the problem been resolved?
Yes | Finished! |
No | Repeat Step 3 to 4. If the problem persists even after decreasing the value in 1246: [Fusing Nip Width Adjustment:Envelope] by 400 milliseconds, contact your service representative. |
(b) Decrease the pressure roller temperature
In [Advanced Settings] for the custom paper, adjust the pressure roller temperature.
<Full-color printing>
Select 1241: [Fusing Temperature], and then decrease the value in [Pressure Roller Temp] in [FC] by 10°C.
<Black-and-white printing>
Select 1241: [Fusing Temperature], and then decrease the value in [Pressure Roller Temp] in [BW] by 10°C.
Print the image. Has the problem been resolved?
Yes | Finished! |
No | Repeat Step 1 to 2. If the problem persists even if you decrease the value in [Pressure Roller Temp] to 30°C, proceed to "(c) Decrease the fusing temperature". |
(c) Decrease the fusing temperature
In [Advanced Settings] for the custom paper, adjust the fusing temperature.
<Full-color printing>
Select 1241: [Fusing Temperature], and then decrease the value in [Heat Roller Temp] in [FC] by 5°C.
<Black-and-white printing>
Select 1241: [Fusing Temperature], and then decrease the value in [Heat Roller Temp] in [BW] by 5°C.
Print the image. Has the problem been resolved?
Yes | Finished! |
No | Repeat Step 1 to 2. If the problem persists even if you decrease the value in [Heat Roller Temp] to -15°C (full-color printing) or -25°C (black-and-white printing), proceed to "(d) Decrease the pre-printing temperature". |
(d) Decrease the pre-printing temperature
In [Advanced Settings] for the custom paper, select 1241: [Fusing Temperature], and then decrease the value in [Corct Temp: Pre-Feed] in [BW/FC] by 5°C.
Print the image. Has the problem been resolved?
Yes | Finished! |
No | Proceed to "(e) Decrease the process speed". |
(e) Decrease the process speed
In [Advanced Settings] for the custom paper, select 1331: [Motor Speed], and then set [Process Speed Setting] to "Low Speed".
Print the image. Has the problem been resolved?
Yes | Finished! |
No | Proceed to "(f) Decrease the fusing temperature". |
(f) Decrease the fusing temperature
In [Advanced Settings] for the custom paper, adjust the fusing temperature.
<Full-color printing>
Select 1241: [Fusing Temperature], and then decrease the value in [Heat Roller Temp] in [FC] by 5°C.
<Black-and-white printing>
Select 1241: [Fusing Temperature], and then decrease the value in [Heat Roller Temp] in [BW] by 5°C.
Print the image. Has the problem been resolved?
Yes | Finished! |
No | Repeat Step 1 to 2. If the problem persists even if you decrease the value in [Heat Roller Temp] to -25°C (full-color printing) or -35°C (black-and-white printing), contact your service representative. |
If the fusing becomes insufficient while solving the problem, perform the procedure described in Improving Fusibility.
After performing this solution, it is recommended to perform the external controller's color calibration. For details, see Operating Procedure for Color Calibration.
