If you notice the symptoms below, just try to recover the good quality same as before.
Paper Jamming
With time and use, the transfer roller on the copier or laser printer may be in incorrect position, try to remove it and replace it back to adjust correctly to ensure the paper can go trough the transfer roller normally again. If this can’t solve the problem, you probably need to replace a new roller.
Paper With Streaking
After the printer working for some time, the printout paper may come out with streaking and black spot, it is possible that the roller is not clean and comes with residual toner, use a dry cloth to wipe it gently and don’t use liquid and chemical material to clean the dirt, because these material can damage the surface of the component.
Noise
With long time use, the clips at two ends are worn and broken to cause the transfer roller to be fixed improperly, so the roller probably has rolling fiction with other components, to avoid further damage, remove the transfer roller from the printer, and replace it back correctly to the slot, and use new clips to lock it, if there is any damage or distortion on the roller, the transfer roller need to be replaced by a new one.
Odor Emission
The reasons mentioned above probably cause that the transfer roller don’t interact with other components, this is why you can smell some strange odor from the printer, so stop the print work as soon as you notice this issue, and clean the roller and reposition it. If the issue can not be solved after print some test files, you need to replace it by a new one.

How To Clean A Upper Fuser Roller
Inside the printer fuser assembly, there are two pieces of rollers, upper fuser roller or fuser roller, and lower fuser roller or pressure roller, the upper fuser roller is a high quality aluminium tube coated with teflon, with a heating element inside, sometimes, we can use a fuser film sleeve to instead of the upper fuser roller. The lower pressure roller is a soft rubber roller.
The best way to clean a fuser roller is to use isopropyl alcohol if you haven't a specific cleaning fluid, just don't use rubbing alcohol, it may contain ingredients that can leave a residue on the fuser surface, you can also use a very light coat of silicon oil and a non linty rag. When the rollers are clean, dry them with another cloth. You can fully disassemble the roller before clean it, but it could be done with minimal removal just so the roller could be turned. The surface of the fuser roller is made of a teflon film that is easily damaged, so use only light pressure when cleaning, and better not to use harsh chemicals like acetone or trichloroethane, pay attention when you clean a fuser film sleeve, as it's very fragile and easily demaged, insert the sleeve into a support, wipe away the old grease from the heating element and apply the new high temperature grease, if you don’t have the grease, remain the old grease.

How Is The Image Printed On The Paper
There are so many laser printer parts inside your printer, the toner cartridge has two main components, one is the drum and the another is hopper. The drum begins to turn around when the printer starts to run, its surface charges with negative electricity from a charge roller. The drum has a layer of sensitive coating on the surface, it gets hit by laser beam and as it turns. As the laser radiates the drum line by line for million times per second, it releases the electricity to create more non-electricity spaces, until they finally form an same image as the document right on the drum, just outside the hopper, there's a roller that gets covered with toner particles as the drum turns past this roller, the toner has no choice since the toner carries a negative electricity to be attracted to the non-electricity spaces on the drum, at the same time, the toner is repulsed by the negative electricity that cover the rest of the drum, so the toner only sticks to the spaces hit by the laser, now the toner forms a same image of the document on the surface of the drum, furthermore, the printer is charging a piece of paper with positive electric charges, the rolling drum carries its toner image down onto the paper, and this is for pulling the toner off the drum to attach onto the page, now the image of that text is on paper.
The last process but not least, the paper need to pass through the fuser assembly, there’s a roller inside to heat up to 200 degrees Centigrade to melt the toner particles and fix onto the paper to finish a printed page.

How To Maintain Upper Fuser Roller
Upper fuser roller is made of seamless alum alloy tube, its thickness is between 1-3mm, and there is a piece of printer heating element set in such a roller to generate heat, the surface of roller is covered with the fluorine resin film, which is usually called as fuser film sleeve. When the paper pass and is jammed in the fuser assembly, just don't pull t out heavily, as such an action may damage the surface coating of the fuser roller, and the damaged parts will fail to fuse the toner particles on the paper. If the paper comes out with some spots and residual toner, it may be due to that the surface of roller is damaged or scratched. When cleaning the surface, just use some cotton with alcohol to wipe gently off the stain on it, and remember that not to use blade to scrape it.

Process Of Applying Grease in Fuser Film Sleeves
Fuser grease is made of silicone oil for lubrication, and it also has excellent performance at thermal conductivity to assist fuser film sleeve to conduct the fusing process. Just like other laser printer parts, we need to replace the grease with use and time, proper operation is very important to be careful when installing, otherwise your fuser film sleeve will be damaged and scrapped totally. Hope the following instruction can be of help to you.
Step 1. Detach the fuser unit and remove the used fuser film.
Step 2. Use alcohol to clean the surface of heating element.
Step 3. Use soft spatula to scoop up grease from the container, total applying amount is around 1 gram.
Step 4. Place the spatula at an angle on the surface, and wipe evenly the grease over the surface of heating element with forward and backward movement.
Step 5. Put the heating element into the fuser film sleeve, and the end of the film with ground ring should be in good contact with the surface of lower pressure roller or the conductive brush after installation.
Step 6. Turn the film sleeve by hands and feel if the turning is smooth.
Step 7. If everything is okay, re-install the fuser unit and make a test.
