I refilled the cartridge, it worked for a week. Then it abruptly began to print very poorly. Faint, with horizontal lines. I filled the cartridge again. No change. I cleaned the head and now it prints even worse. What does print does not appear black, but blue.

Sounds like a line of magenta, actually. Which suggests a number of things that *could* be wrong. If the ink cartridges are full one could be faulty. If you refill them this is almost certainly the case and replacing the head/cartridge will fix the problem.

The place to start though is the printer tools - in the software there should be a button somewhere on a Maintenance page that does "Nozzle Clean". That's what you'd check first.

If the hardware seems ok then removing the printer, deleting the old printer driver and reinstalling a new printer driver may also fix the problem.

Oh, I have the WF-3520 btw and it's a top performer for business printing. (not so great for photos...) Follow the suggestions and see what happens. If it doesn't get better after a nozzle clean, make sure you've removed the magenta cartridge (well, all of them is a good idea) and put them back in making sure they all 'click' nicely.

the white ghost lines are down to the charge wire within the toner cartridge being dirty, the only real way forward is to replace the toner cartridge as access to the charge chorona wire is not possible without ruining the cartridge itself

I would not advise you to refill a toner cartridge becausethe toner powder is very fine and you do not want to breath in this tonerpowder.When the toner cartridge is exhausted or empty then theprinter will not be able to print further documents or the prints will be veryfaint.You may be able to print a few more pages by removing thetoner cartridge and shaking the toner cartridge in a horizontal position a fewtimes and then placing it back into the printer.This will give you an opportunity to print a few more pages and giveyou time to purchase a new toner cartridge for your printer. A cheaperalternative is to purchase a re-manufactured toner cartridge for your model printer.A re-manufactured printer cartridge also replaces worn partsas well as refilling with toner powder.

You need to remove the black/yellow printhead and dab it on a damp paper towel until you see a solid line of black ink on the towel when you press it. It won't pass the alignment until all colors work properly.

You have an air bubble between your print head and ink supply. This is something that commonly happens when you hand fill these cartridges. These cartridges need to be filled under vacuum to prevent this from happening. I recommend refills from Cartridge World because they have good prices with a 100% satisfaction guarantee.

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

Fame !

Amand321,

Your problem lies with the fact that you manually refilled your cartridges. This is not recommended by any technician I know and your solution is in the replacement of all your cartridges with genuine brother consumables. It is going to be expencive, but it is the only real solution.

If you are seeing lines it is the cartridge and it's bad.

Refilled cartridges usually only work about one time and then the cartridges run into problems. They either leak or the cause lines in the copies.

If you can return and get a non refilled one, that should work.
