I have ink on the roller and have to wipe it off it works for a few pages then ink gets on it again do I need to bye a new drum

It sounds like either your drum needs to be replaced (needs to be done every 5 or 6 toner cartridges), or you have a bad fuser (depends on what you mean by smearing).

When an image reappears further down the page (not as dark or bold) it usually means that the current in the drum is not correct, or the coating on the drum is worn. Take the cartridge assembly out and separate the drum from the cartridge. DO NOT TOUCH THE DRUM ROLLER. Look at it and see if there are streaks, color differences, or toner on the drum roller. The roller should be solid purple or green with no marks, lines, toner, or smudges on it. If it does, the drum is a replaceable part and you can get one anywhere that sells toner cartridges. They are even available in remanufactured brands.

However, if there is loose toner on the paper (wipe your hand over it and it comes off), then your fuser is bad and needs to be replaced. Another problem with the fuser you can check is whether there is toner being adhered to the fuser rollers, which could cause smearing and images to reappear on the page. To check this, open the rear cover of the printer. Inside you will see two rollers: usually an orange one on top of a black one. Be careful; the fuser can heat up to almost 400 degrees, so let it cool if you were just using it. Check to see if there is any toner on these rollers; if working properly, they should be spotless. If there is toner visible on either roller, then you may need to replace the fuser.

It is a 75% chance of your drum being the cause, which would be the problem to hope for. If your fuser is bad, in all honesty it may not be worth fixing; it can cost you up to $150.

I hope this helps! Good luck!

Are the spots at 94mm
intervals? (The problem is not solved after printing a few pages.)

1) If toner or glue remains stuck, wipe it off gently with a
cotton swab. (Refer to NOTE in thebottom of this page.)
2) If the photosensitive drum is scratched or deteriorated (exposed), replace the drum
unit.

Are the spots at 79mm intervals?..

1) Check and clean the heat roller with a cloth dampened with alcohol.
2) Replace the fixing unit.


NOTE:
Clean the drum unit as follows:
(1) Remove the toner cartridge from the drum unit Place the printing samples in front of the
drum unit, and find the exact position of the image defect.
(2) Turn the drum gear by hand while looking at the surface of the photosensitive drum.
(3) Wipe the surface of the photosensitive drum with a cotton swab until the dust or paper
powder on the surface comes off.
!CAUTION:
Do not wipe the surface of the photosensitive drum with something sharp. (ball-point pen
etc.)
Use cleaning liquid which is a 50-50 mixture of ethyl alcohol and pure water.

Had a similar problem. The following solution from the Brother site seemed to fix it.

1. Gently wipe the scanner window with a soft dry cloth. The scanner window is located on the roof of the inside of the printer.
2. On the top of the drum unit (DR400), locate the blue tab on the left side. Slide it back and forth across the drum about 30 times.
3. Remove the toner cartridge (TN430 or TN460) from the drum unit. To remove the toner from the drum: hold down the blue lever on the right side of the drum and lift the toner off of the drum unit.
4. Inside the drum unit there is a green roller. Wipe the green drum roller with a dry tissue (i.e. Kleenex). You may turn this roller by moving the gears on the far left side.

I don't think WD40 oil is the best solution.

I had to do such a procedure a few months ago. - I got a drum which was not in use some month. This is normally no problem with original ink. But some cheap plagiators have their own ink recipe.

I used a solvent for professional offset printers. It is the one to clean the ink rollers with. it was blue colored and I think it is so with most manufacturers. (I have seen some brands for this purpose and all were lighter or darker blue.)

By the way, it isn't so easy as it seems: The drum looks clean enough after some time. But to remove really all of the hard and gummy ink inside I had to take the drum apart. It took so much time and was so dirty so I will do this again only if I get paid accordingly.

You are going to need a new drum unit. This is the cartridge that is located right next to your toner cartridge. What is happening is the drum bleaning blade has gone bad and is not cleaning the drum properly. You can have these rebuilt but with parts and labor they usually end up costing more than just replacing the whole unit yourself. You can find them on the internet for around $125.00. Make sure if you order one that it is the whole unit not just the drum. For example a drum alone is around $40 - $50 VS the $125 for the cartridge.
Good Luck and Thank You for using Fixya.

I have a Dell 5100CN, and believe that this problem is caused by the drum not releasing the full charge which holds the ink in place on the drum until the page is printed. After the image is transfered to the Drum, the 'Fuser' unit heats up the paper and pressure forces the paper against the drum to transfer the toner from the drum to the paper.

Since the Image is printing, and you are getting a ghost, I guess that the problem is most likely the 'Pressure Roller' or 'Heater' in the 'Fuser' unit.

Buying the Fuser unit from Dell could cost you around $200 from Dell, but I just found one on eBay for $129 Got to www.ebay.com and search for item number 190388919845

I highly recommend that you buy a new OEM (original Equipment Manufacturer (Genuine Dell)) 'Fuser Unit'

Good Luck

ur drum is broken it needs to be replaced

The drum should never be touched with anything; the surface is sensitive in the extreme and I suspect you have finished it off. 
The refilling of the toner cartridge isn't really a DIY job on this unit.
Yes, it will cost a few dollars but it's either this or a new unit. Although now retired, I had very good service from Precision Roller and I can recommend them highly:
Xerox toner & drum cartridges

You might need a new drum. This usually happens when the drum roller needs cleaning. Try your luck and see if there is any spot (clogged ink) on the drum roller. Otherwise, change the drum kit.

There are several things that can cause this. A worn toner cartridge and/or transfer roller can cause vertical smears, but it may also be a worn fuser assembly. The teflon coating on the fixing (heat) roller wears off, and leaves vertical streaks of varying widths on the pages. Sometimes you may see "ghost" images on the pages for the same reason. Open the back door of the printer, and hold down the exit guide on the fuser (carefull, it may be very hot). There are two long rollers, the lower one is black, the upper roller is either grey or shiny brown. That's the teflon coating. See if it's peeled or damaged. If so, replace the fuser assembly.
