How to change toner cartridge TN330


Hello

Once you have the correct Brother Toner for your printer model, power your printer OFF and open the cartridge box.

Next, you need to open the top cover of the printer. You should do this carefully to prevent damage to the interior or exterior of the printer.

Once the printer top cover is removed, you want to extract the empty Brother Toner cartridge from the printer by pulling upward and away from the machine. You should be able to do this without a great amount of force.

After you've taken the Brother Toner cartridge from the printer, you want to prepare the new cartridge for insertion. To do this, you need to remove it from the plastic bag it is contained in. Next, you need to remove the rip strip from the cartridge. The rip strip is attached to a plastic film strip. Removing the rip strip is important because if you don't your printer will only produce blank sheets. Take care when ripping the strip off, as you may get Brother Toner on your clothes which can stain. If you end up spilling toner on yourself you can wash it off with cold water.

Next, you want to place the new cartridge in the printer the same way the old Brother Toner cartridge came out. There will most likely be arrows on the package to guide you in the placement that will help you make sure you're putting it in correctly. Much like removing the used Brother Toner cartridge, it should slide in with minimal force. If it doesn't slide in easily you should make sure that the Brother Toner cartridge is the correct cartridge for your model printer and then make sure that it is aligned correctly.

Once you have the cartridge in the printer properly, put the printer lid back on.

Now you are going to print a few test pages to make sure that everything is working the way it should. If the printouts look good: You are done. Package the old toner cartridge in the box the new toner came in and recycle it. If the printouts look bad: Sometimes cartridges can be defective. If there were problems with your test pages, you may need to try the process again with another toner cartridge.

A new laser could help, but you should make sure the toner save is turned off, it makes toner last longer by making light prints. Toner save is set in printer properties in the control panel

Brother MCF-7340 first time toner replacement


If this model comes with the drum separately of the cartridge, only replace the cartridge. There's no need to change it every time. until prints start to get lines or dots. Don't expose the drum to light too much.

Brother MFC6800-says change drum soon - is that hard to do?


yes anyone can do this, the drum is the unit the toner fits into, remove as though you were removing the toner cartridge, that the toner all the way out of the drum unit and install the old toner in the new drum and slide back into printer, again the drum unit is just the casing that your toner cartridge slips in and out of

Printer smears on cold print


The toner cartridge sounds like the problem to me. Did you refill it? Or have it done? It sounds like an incompatible brand......toner is very model specific, and not just 'any' will do, and it often doen't mix well with the remaining toner i the cartridge if it is not completely disassembled and cleaned out. Just curious

After replacing the toner, an abnormal sound of wheels coming


I just had the same problem.....I changed drum and toner at the same time.....bad sounds....tried old toner with new drum and "new" toner with old drum.....seems that the gears that move the toner and the drum were not meshing correctly. I determined that it was the "new" toner. I discarded new toner and used a different one....that fixed it
