I thought maybe you have the paper size set to Landscape rather than Portrait. If not, then you might look at:

I did some searching on that site and it yielded the hlep below which may give you some help.


Issue: How do I set my printer so my printout fits the paper size I am using?
Solution: Use the recommended Print Area MP240

Printing Area To ensure the best print quality, the machine allows a margin along each edge of media. The actual printable area will be the area inside these margins.
Recommended printing area (dark blue):
Canon recommends that you print within this area. ()
Printable area (light blue):
The area where it is possible to print. ()
However, printing in this area can affect the print quality or the paper feed precision.

Note
Borderless Printing
By selecting the Borderless Printing option, you can make prints with no margins.
When performing Borderless Printing, slight cropping may occur at the edges since the printed image is enlarged to fill the whole page.
For Borderless Printing, use the following paper.
- Glossy Photo Paper "Everyday Use" GP-501
- Photo Paper Glossy GP-502
- Photo Paper Plus Semi-Gloss SG-201
- Photo Paper Pro Platinum PT-101
- Photo Paper Plus Glossy II PP-201
-Photo Paper Pro II PR-201
- Matte Photo Paper MP-101
Performing Borderless Printing on any other type of paper may substantially reduce printing quality and/or result in printouts with altered color hues.
Borderless Printing on plain paper may result in printouts with reduced quality. Use them only for test printing. You can perform Borderless Printing on plain paper only when printing from your computer.
Depending on the type of paper, Borderless Printing may reduce the print quality at the top and bottom edges of the paper or cause these parts to become smudged.

Laser Printers that printouts can be smudged usually means the Transfuser (the part that settles the toner onto paper) is not fully functioning or damaged. Simply replace it and it should be back to normal. However, these Transfusers are quite expensive. So you may be better off to get a quote for a new one if out of warranty.

replace fuser. How far apart is the ghost image?

ERROE E000602-0003

sounds like a bad drumbur also can be caused by a defective fuser.

Usually ghosting is caused by the fusing unit, which usually means that it needs replaced to be honest. You could try getting into the fuser and giving the rollers a wipe, they may have dry toner on them which could also cause the fault. but i'd say the fuser could need changed!!!
Hope that helps  (",)

Good Evening Robert,

The setting for non dell toner only controls the fuser temperature, and will not cause you any print quality issues. Toner is actually made up of ink and plastic. The fuser melts the plastic to "fuse" the image to the paper. Dell toner is set to "fuse" at a specific temperature. when you use non Dell toners, the temperature required to fuse may be different, and when set to non dell toner setting, the fuser temperature is raised to the maximum to ensure the other toner fuses properly. The down side to this is that you will wear out the fuser sooner then it should.

As far as the print quality issue you are having, it is most likey caused by the imaging drum.

Regardless of the estimated life for the imaging drum as stated by the printer, this is just an estimate. Many things can and will cause the imaging drum need replacing. ( Just yesterday I replaced a black toner in a 3115 that was less then a month old... genuine Dell... with more then 75% expected usage left because it was defective).

On this printer, each of the 3 colors and the black are all independent of each other with the exception of the imaging drum. Even within the imaging drum, cyan and black are independent of magenta and yellow on the first stage of transfer. When you have deteriorated print quality that effects more then one color, the first step is to replace the imaging drum.

The Primary transfer, secondary transfer, and tertiary transfer of the image are ALL contained within the imaging drum.

The chances of having 3 or 4 bad Developers is very very slim. If your print quality issue was related to only ONE color, then I would say you had a bad developer unit ( the 4 items located behind the imaging drum when removed). These are far more difficult and expensive to change.

The BTR ( bios transfer roller ) is the only other item that "could" effect your print quality, however, based on the symptoms you discribed, I doubt it. Besides, if i am not mistaken, the imaging drum kit comes with a new btr anyway.

Although I am sure you may be disappointed with the fact the drum unit is failing while showing it still has life remaining, the solution to replace it should restore your unit to full operation. The unit is light sensative, and effected by physical age as well as the number of prints it has supplied.

Please evaluate the solution i have provided and, rate the solution appropriately to show your support.

Thanks,
Cory

Sounds like the transfer roller or the fuser unit may be faulty. Look at the fuser to see if the roller surfaces are dirty. If so, replace the fuser.

Are you using genuine Brother color cartridges? If you are, then try different paper (20 pound laser printer paper or plain paper copier paper rather than inkjet paper,) Also, do not use recycled paper. If that does not work, you may need a new imaging (OPC belt) unit, or a new fuser assembly. Check your owners manual about when to replace the imaging unit or fuser. It is usually after 60, 000 prints have been run.
