Symptom:

Fusing offset occurs at the edge or center of the paper.

The customer may report a strange odor coming from the machine.

Cause:

The temperature is too low at the edge or center of the paper when the paper enters the fusing unit.

Solution:

If the symptom occurs, do the procedure in the Flowchart below.


Workaround A:

Change the paper tray setting (paper thickness setting) in User Tools to match the actual paper thickness.
*1: User Tools > Tray paper setting > page 2 > Select tray > Select paper thickness

Workaround B:

Change the paper tray setting in User Tools.

  • There is no workaround for Thick Paper 4.

Thin paper -> Plain paper

Plain paper -> Mid thick (For MP 5055/6055 models, Plain paper -> Thick paper 1)

  • The copy speed will be reduced from 60cpm to 50cpm on the MP 6055 model.

Mid thick -> Thick paper 1

  •  The copy speed will be reduced (See the chart below).

Thick paper 1 -> Thick paper 2

  • The copy speed will be reduced (See the chart below).

Thick paper 2 -> Thick paper 3

Thick paper 3 -> Thick paper 4

  • Auto duplex cannot be used (See the chart below).

Postcards: Thick paper 2 -> Thick paper 3

Side effects: The following may occur, depending on the paper thickness.

  • Paper curl
  • Decreased productivity
Workaround C:

Increase the target fusing temperature by 5 degrees using the following SPs:

  • SP 1-105-003
  • SP 1-105-007
  • SP 1-105-011
  • SP 1-105-015

If the symptom occurs with 1200 dpi printing, also increase the target temperature by 5 degrees for these SPs as well:

  • SP 1-105-107
  • SP 1-105-137
  • SP 1-105-111

Side effects: Paper curl may occur.

Workaround D:

Change the target temperature using the following SPs as shown below.

  • SP 1- 105-019: 145 deg -> 150 deg
  • SP 1- 105-023: 130 deg -> 140 deg
  • SP 1- 105-027: 135 deg -> 140 deg
  • SP 1- 105-141: 140 deg -> 145 deg
  • SP 1- 105-115: 120 deg -> 125 deg (For 1200 dpi mode)

Side effects: Paper curl may occur.

Workaround C':

Increase the target fusing temperature by 5 more degrees using the following SPs:

  • SP 1-105-003
  • SP 1-105-007
  • SP 1-105-011
  • SP 1-105-015

For 1200 dpi printing:

  • SP 1-105-107
  • SP 1-105-137
  • SP 1-105-111

Side effects: Paper curl may occur.

Workaround D':

Increase the target fusing temperature by 5 more degrees using the following SPs:

  • SP 1- 105-019: 145 deg -> 150 deg -> 155 deg
  • SP 1- 105-023: 130 deg -> 140 deg -> 145 deg
  • SP 1- 105-027: 135 deg -> 140 deg -> 145 deg
  • SP 1- 105-141: 140 deg -> 145 deg -> 150 deg
  • SP 1- 105-115: 120 deg -> 125 deg  -> 130 deg (For 1200 dpi mode)

Side effects: Paper curl may occur.
