  • Page 29: Ghosting

    Color Toner Spotting/Staining Partially stained background CEZ544 Cause: This may occur because of wearing of the developer and drum unit or staining of the charge roller. Solution: If a message prompting replacement of a unit has appeared, replace the unit. In the [Machine: Image Quality] group on the [Adjustment Settings for Skilled Operators] menu, select [Adjust Image Density/ DEMS] and execute [Image Density Adjustment: Manual Execute].

  • Page 30: Scratched Images And Stained Paper Edges

    3. Troubleshooting Image Quality Problems 189 mm (7.5 in.) CNT007 Cause: The image transfer current is transmitted to the drum, where a potential difference occurs between a developed area and non-developed area and causes the intended image to be reproduced. This may occur if: •...
  • Page 31 Color Toner Spotting/Staining CNT008 Cause: When a relatively stiff, thick paper is delivered, the entrance guide plate for the transfer unit is warped toward the intermediate transfer belt due to the stiffness of the paper. The edge of the entrance guide plate comes into contact with the toner on the belt to cause images to be scratched and paper edges to be soiled.

  • Page 32: Toner Scatter

    3. Troubleshooting Image Quality Problems Toner Scatter Toner Scatter (1) Toner is scattered around a solid-fill print. CEZ545 Cause: This may occur if printed at low temperature or humidity. • To adjust the following settings, pre-register the type of paper in use as a custom paper. For details about registering custom papers, see "Registering a Custom Paper", Paper Settings Reference.

  • Page 33: Toner Scatter (2)

    Toner Scatter Adjust the setting for the side 2 of the paper. Configure the following settings in [Advanced Settings] for the custom paper in use. <Printing in black and white> Increase the scaling factor by 5 percentage points in [Paper Transfer Current: BW: Side 2]. Example: If the present value is 100%, change it to 105%.
  • Page 34 3. Troubleshooting Image Quality Problems • To adjust the following settings, pre-register the type of paper in use as a custom paper. For details about registering custom papers, see "Registering a Custom Paper", Paper Settings Reference. Solution: The solution depends on the area in which the line splatter occurs. If the splatter occurs 5 mm (0.2 inches) or less from the leading edge, follow Procedure (a) on the following page;...

  • Page 35: Toner Scatter (3)

    Toner Scatter Toner Scatter (3) Parts of a line or character exhibit splatter. This may occur in a line or character that is 8 to 13 mm (0.3 to 0.5 inches) from the trailing edge and 20 mm (0.8 inches) or less from the left edge facing the paper feed direction.
  • Page 36 3. Troubleshooting Image Quality Problems Check the present value. Is it lower than 50 A ? Carry out all of the following: (1) Increase the value by 5 A in [Image Transfer Current: FC: K]. (2) Set [Paper Transfer Current: TE: FC] to "200%". (3) Set [Paper Transfer Current: TE Length: FC] to "30 mm".

  • Page 37: Color Loss

    Color Loss Color Loss Colorless Spots Colorless spots appear in solid-filled areas. CEZ547 Cause: If the toner contains small clots, they fail to be transferred, producing colorless spots. This problem may occur if the machine is left unattended for a long period or the toner bottle is taken out of its moisture-proof bag for a long period of time.
  • Page 38 3. Troubleshooting Image Quality Problems 189 mm (7.5 in.) CEZ548 Cause: The photoconductor unit is stained. Solution: To identify the affected color, print three full-page, solid-fill A3 or DLT sheets for each of cyan, magenta, black, and green. Because it is difficult to identify white spots on yellow, green is used instead of yellow. Detach the photoconductor unit of the affected color and check the drum surface.

  • Page 39: Vertical White Streaks

    Color Loss Vertical White Streaks White streaks of 1 to 8 mm (0.04 to 0.3 inches) long and perpendicular to the paper feed direction appear.

In the [Machine: Image Quality] group on the [Adjustment Settings for Skilled Operators] menu, select [Density Difference: Across Feed].
  • Page 49 Density Problems Cause: At low temperature or when using thin coated paper, this may occur if the paper transfer current is insufficient. At high temperature, this may occur if the paper transfer current is excessive. • This solution only works when the thickness of the paper is equivalent to Paper Weight 4 or higher. Do not try this as a solution when using paper with a thickness equivalent to Paper Weight 3 or lower, as it may cause paper misfeeding.

    5. Post-Processing Option Troubleshooting Cause: When a particularly dense image is printed, the paper feed rollers may become soiled with toner and the paper edges may in turn be soiled by the toner on the paper feed rollers. Solution: For details about cleaning the paper feed rollers, see page 84 "Cleaning the Paper Feed Path". Paper Edges Are Stained (3) (Finisher SR5070 / Booklet Finisher SR5080) Cause: When Z-folded paper is punched, the paper edges may become stained.

This is referred to as folding deviation. Solution: Change the folding position by adjusting the position of the paper edge stopper for folding. •...

  • Page 99: Folding Deviation

    Multi-Folding Unit Folding Deviation Cause: Depending on paper hardness, folding deviations (skewed folding) may appear. A deviation may appear if the edge dimensions of the parts between folds are different. For example, in the following illustration, the dimensional difference between the top (L2[2]) and bottom (L2[1]) edges is a deviation.

  • Page 107: Folded Sheets Are Not Stacked Properly

    Multi-Folding Unit Folded Sheets Are Not Stacked Properly Cause: If a large number of half-folded multi-sheet is delivered, the edge of the sheets may bulge and some part of the edge will be swollen. If this happens, other sheets loaded on the bulged paper may turn over in the output tray.

    6. Improving Throughput Reducing the Waiting Time Prior to Printing After receiving a print job, the machine usually stops to let the fusing temperature reach an appropriate level for printing. The waiting time for the fusing unit to cool down may be quite long, especially before printing on thin paper.

    6. Improving Throughput Improving Throughput when Printing Black- and-White Jobs and Full-Color Jobs When printing intermixed black-and-white and full-color print jobs, switching from full-color mode to black-and-white mode takes time, causing loss of throughput each time the mode is switched. When the machine prints a full-color print job followed by a black-and-white job, you can improve throughput by adjusting the number of black-and-white sheets the machine prints in full-color mode before switching to black-and-white mode.
