3. Specifying and Checking Paper Settings

• To adjust the following settings, pre-register the type of paper in use as a custom paper. For details about registering custom papers, see "Specifying a Custom Paper", Preparation.

Solution:

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

Procedure 1: Changing the fusing temperature

1. In [Advanced Settings] for the custom paper you are using, select 1232: [Fusing

Temperature], and then adjust the value in the following corresponding settings by 5°C.

• [BW/FC/FCS]

[Heat Roller Temp]

• [FCS]

[Heat Roller Temp: Clr/Sp], [Heat Roller Temp: White]

• [S]

[Heat Roller Temp: Clr/Sp], [Heat Roller Temp: White]

• [BW/FC/FCS: Fuser Setting HQ]

[Heat Roller Temp: Clr/Sp], [Heat Roller Temp: White]

• [FCS: Fuser Setting HQ]

[Heat Roller Temp: Clr/Sp], [Heat Roller Temp: White]

• [S: Fuser Setting HQ]

[Heat Roller Temp: Clr/Sp], [Heat Roller Temp: White]

2. Print the image and check toner fusion. Has the problem been resolved?

Yes Finished!

No Increase the temperature an additional 5°C.

3. Repeat Step 2.

If the problem persists even if you increase the temperature to 190°C, perform Procedure 2,"Image processing 1".

Procedure 2: Changing the print speed

This will slow down the printing to give the toner more time to fuse. However, because of this, throughput will be reduced.

Adjusting Paper Settings

For details about "Print Speed setting", see "Details of Menu Items in Advanced Settings", Adjustment Item Menu Guide.

1. In [Advanced Settings] for the custom paper you are using, select 1231: [Print

Speed], and then decrease the value in the following corresponding settings by one step.

• [BW/FC/FCS]

• [FCS: Fuser Setting HQ]

[Clear/Special], [White]

• [S: Fuser Setting HQ]

[Clear/Special], [White]

If the present value is [High], select [Middle]. If it is [Middle], select [Low].

2. Print the image and check toner fusion. Has the problem been resolved?

Yes Finished!

No Go to the next step.

3. Is the process speed set to [Middle]?

Yes Set the process setting to [Low].

No If the problem persists, contact your service representative.

4. Print the image and check toner fusion. Has the problem been resolved?

Yes Finished!

No If the problem persists, contact your service representative.

• Changing the fusing temperature or changing the process speed may produce one or more of the following side effects:

• Paper curling

Streaks and bands appear. Proceed to "Chapter 5 Image Quality

Problem: Lines".

Spots appear. Proceed to "Chapter 6 Image Quality

Problem: Spots".

Uneven thickness, stains, or spots appear.

Proceed to "Chapter 7 Image Quality Problem: Full Page".

What is the problem you want to solve

related to image quality?

DFP676

3. Specifying and Checking Paper Settings

• Paper misfeeding

• Blisters

• Glossy lines

• Change of gloss

• If one or more of the above side effects occurs, adjust the fusing temperature and process speed by decreasing the fusing temperature and increasing the process speed.

• After performing the solution, it is recommended to perform the color calibration of the external controller.

• Check the toner fusibility as follows:

• The printed image does not come off.

• The toner does not come off even if it is lightly rubbed by a nail.

• The toner does not come off even if it is rubbed by the cloth for cleaning the contact glass.

5. Image Quality Problem: Lines

• If white streaks appear at 189 or 40 mm (7.5 or 1.6 inches) intervals, carry out the procedure in see page 53 "Black (color) Spots (1)".

• After performing the solution, it is recommended to perform the color calibration of the external controller.

• Do not use ethanol or any other organic solvent to clean the charge roller. Otherwise it may cause damage to the charge roller.

Vertical Black Streaks

Short black streaks appear on a black halftone image.

Cause:

A sheet is bent at the entrance to the fusing unit and comes into contact with the edge of the paper delivery tank, where static electricity builds up on the sheet through friction. This causes scattering of unfixed toner on the paper surface.

This may occur if:

• Printing is done at low temperature or humidity

• The thickness of the paper is equivalent to Paper Weight 2 or lower

8. Troubleshooting Paper Delivery Problems

Frequent Paper Misfeeds

Depending on the cause of the problem, do one of the following:

Have you ruffled the paper sufficiently?

Double feeding may result if the paper is not ruffled properly.

Remove the paper, ruffle it, and reload it.

For details about ruffling the paper, see "Fanning the Paper", Preparation.

Coated or another type of unsupported paper is loaded in the machine's tray.

Load paper not supported by the machine's paper tray (Trays 1-2) in the wide LCT or another paper tray supporting the paper.

For details about the size and type of paper that can be loaded in the paper trays, see "Recommended Paper Sizes and Types", Preparation.

The side fences in the paper tray are too close together.

If the distance between the side fences is less than the paper width, it may interfere with paper transfer and so cause paper misfeeds.

Adjust the side fences to match the paper width.

When you close the paper tray, the side fences may become misaligned due to the weight of the paper. To prevent this, close the paper tray slowly.

For details about loading paper, see "Loading Paper", Preparation.

The side fences in the paper tray are too far apart.

If the side fences are too far apart, paper misfeeds may occur due to wrong paper size detection.

Adjust the side fences to match the paper width.

For details about loading paper, see "Loading Paper ", Preparation.

The paper size/orientation/type is not specified correctly.

In tray paper settings, specify the size, orientation, and type of the paper in use.

For details about tray paper settings, see "Changing the Paper Size", Preparation.

Too many sheets of paper are loaded in the paper tray.

When loading paper, do not exceed the limit.

8. Troubleshooting Paper Delivery Problems

For details about how many sheets can be loaded in the paper trays, see "Recommended Paper Sizes and Types", Preparation.

The edges of the sheets are rough.

Turn the sheets the other way up or smooth the edges before loading.

Sheets are curled or wavy.

• Flatten curls and waviness before loading paper.

• Turn the sheets the other way up or smooth the edges before loading.

• Stacking too many sheets may cause the sheets on top to curl greatly. If this happens, reduce the number of stacked sheets.

Sheets absorbed moisture and became limp.

Sheets that will not be used for a long time should be protected from moisture by, for example, storing them in a sealed bag.

If the machine is plugged in, the heater inside the paper tray starts operating when the main power is off to prevent sheets from absorbing moisture.

Depending on the country of use, the paper tray heater may not be supplied. For details, contact your service representative.

When using thick paper or slippery paper.

Enable the Pickup Assist setting. You can specify the Pickup Assist setting for the machine's paper trays (Trays 1 and 2), bypass tray, and the three-tray wide LCT (LCIT RT5090).

In [Advanced Settings] for the custom paper you are using, set [Pickup Assist] of 1312: [Main/3Tray LCIT/Bypass] to [On].

In the [Machine: Paper Feed/ Output] group on the [Adjustment Settings for Operators] menu, set 0303: [Pickup Assist Setting] to [On].

The paper feed sensor is stained with paper dust.

Clean the part of the paper feed sensor where the paper misfeed is detected.

For details about cleaning the paper feed sensor, see page 101 "Cleaning the Paper Feed Path".

The transfer roller is stained, affecting paper delivery.

Clean the part of the paper transport roller where the paper misfeed is detected.

For details about cleaning the paper transport roller, see page 101 "Cleaning the Paper Feed Path".
