Streak along edge of paper, Canon MF8380Cdw

It sounds like the print quality issue you're experiencing with your Samsung CPL-325 printer may be caused by a few different factors. Here are some steps you can take to diagnose and resolve the problem:

1. Check the toner cartridges: The first step is to check the toner cartridges to make sure they are not empty or low on toner. If they are, replace them with new cartridges. Additionally, make sure that the toner cartridges are installed properly.
2. Check the drum unit: The drum unit is responsible for transferring toner to the paper during the printing process. If it is dirty or damaged, it can cause faded or streaky print quality. Try cleaning the drum unit with a soft, dry cloth or replace it if it appears damaged.
3. Check the paper: Ensure that you are using the correct type of paper for the printer. Using paper that is too thick, too thin, or too glossy can cause print quality issues. Try using high-quality, recommended paper for your printer.
4. Check the fuser unit: The fuser unit is responsible for fixing the toner to the paper. If it is dirty or damaged, it can cause print quality issues. Try cleaning the fuser unit with a soft, dry cloth or replace it if it appears damaged.
5. Check the transfer roller: The transfer roller helps transfer toner from the drum unit to the paper. If it is dirty or damaged, it can cause print quality issues. Try cleaning the transfer roller with a soft, dry cloth or replace it if it appears damaged.
6. Check the print driver settings: Make sure that the print driver settings are configured correctly for the type of paper and print quality you are using. Adjusting the print quality settings may help improve the print quality.

Just to clarify, you are stating INK? The Canon PC941 uses an OEM (Original Equipment Manufacturer) Toner Cartridge. Canon toner cartridges for PC941 printer are supplies produced by the same manufacturer that makes given piece of equipment. Toner cartridges produced by Canon are called OEM. Remove the toner from the machine and then use cotton swabs and alcohol to clean around the roller wheels of all drawer areas. Be sure to unplug the equipment before attempting to clean the wheels.

Her are somethings to try.

1. Paper jam
2. Bad toner cartridge or bad toner.
3. Clean the corona wire (see the manual)
4. Drum is wearing out and needs to be replaced.

Sometime a small piece of paper can get jammed in the toner cartridge roller and cause this type of problem.
Also, often this seen with after market toner cartridges or refilled cartridges. Poor quality or old toner will clump inside the cartridge roller wiper blade. Just like dirt under the wiper blade on an auto, it will leave streak on the toner roller that are transfered to the print drum.
Take a look at the toner cartridge first and inspect the long black roller. If the streaks are there then you need a new cartridge.
If no on the roller streaks try to clean the corona wires.
Also inspect the drum to see if has streak. Try wiping drum with soft tissue paper to see if it come off or is etched into drum.

Hello, this one is fairly simple to diagnose, Change the toner cartridge, does the problem go away? if yes the toner is the problem. If the problem remains it would most likely be the fuser, in which case it would likely need servicing and the fuser replaced.

You need to reset the flag gear for the cartridge to function. I own a Cartridge World printer cartridge refilling store and I would not recommend drill and fill of this cartridge unless you absolutely don't care about the quality of your prints. This cartridge recycles toner, so you build up paper fibers in the toner which wears on the drums and blades of the cartridge to give you very decorative streaky printing. I'm sure you can find flag gear reset instructions on the internet.

Print 3 pages. Use the manual feed tray. As they print, open the cover, remove the toner and look down at the paper in the printer. Do you see marks along the edge? If no...replace the fuser. If yes...it could be the transfer roller.

Hi,
At most cases of printer, especially which have done refill at cartridge, print quality is poor or streaky. Many factors influencing this printed result. To overcome print quality is poor, maybe following tips can usefull to prevent printed pages are missing lines or streaky.

First step is ordinary to be done many people when print quality is streaky that is doing cleaning. To get good printed result, sometime this facility is used more than once.
Use Ink Refill with Quality Nicely
For printer have refilled, sometime the quality of printing is also influenced by ink. If will fill your printer again, use ink which the was quality of nicely. I have tested some refill inks at cartridge which have been ascertained still nicely ( sorry: I do not want to publicize result of this attempt). In the reality result make me surprise, there ink of refill making the printed quality is crummy. To choose ink refill read following tips :

• See viscosity of ink, every merk of ink refill have difference of viscosity. Don’t use Ink refill too jell. Difference of this viscosity is no measure reference viscosity of ink from factory maker of printer
• Don’t fear to try some inking merks. Done this, you’d find refill ink fitt with your printer. I now only using one merk of refill ink ?.
• This suggestion of forum, but I still not yet proved. May believe or not. Good ink aroma of soft usually.

Change Original Cartridge
This is last choice. A lot not like to do this ways, because price of original cartridge still costly. Alternative, you can use compatible cartridge which the was price of cheaper than original cartridge. At newest printer, usually there are two until four cartridge in one printer. And price four same cartridge almost at the price of printer even there are some costlier.

Let me know !

Thanks
