Are TN450 and TN420 toner the same?

Yes! They are physically identical and are both compatible with your Brother printer. The only difference between them is that the TN450 cartridge is the High-Yield version, meaning it has more toner and can print more than the standard yield Brother TN420 toner. The Brother TN420 toner can print about 1,200 pages per cartridge while the TN450 toner yields over double the amount with 2,600 pages. We believe our customers deserve more for their money, so we always offer our High-Yield toner cartridges as our default.

How do I change my TN450 toner cartridge?

Changing your empty supply out for a new Brother TN450 compatible toner cartridge is simple and can be achieved by following the steps below: 

Step 1: Make sure the printer is on, and you are receiving either a “Toner Low”, “Replace Toner”, or “Toner Ended” message accompanied by a blinking LED light. This indicates that the TN450 toner cartridge is in need of replacement to function properly.

Step 2: Press the release button on the front cover to open it.

Step 3: Take the drum unit and toner cartridge assembly out of the printer.

Step 4: Push the green lock lever on the drum unit and take the used TN450 toner cartridge out. 

Step 5: Remove the new Brother TN450 from its packaging. With both hands hold and gently rock the cartridge side to side several times to evenly distribute the toner inside the TN450.

Step 6: Pull the plastic protective cover off of the Brother TN50 toner cartridge.

Step 7: Immediately insert the new toner cartridge firmly into the drum unit. You will hear a locking sound as the green lock lever will lift automatically.

Step 8: To clean the corona wire, gently slide the green tab on the drum unit back and forth to remove excess toner. 

Step 9: Place both the drum unit and the Brother TN450 assembly back into the printer, then close the cover. 

Will compatible TN450 toner cartridges work with my printer?

Compatible Brother TN450 toner cartridges are designed to function and fit inside your printer exactly as an original TN450 cartridge would. If your printer accepts TN450 or TN420 toner cartridges, then you have absolutely nothing to worry about. If you are having trouble fitting your toner cartridge into the printer, sometimes they do require a firm push to properly install. 

What is TN450 toner shelf life?

If stored properly and under normal conditions, it can last up to 24 months. 

Do I need to change my drum unit every time I install a TN450 toner refill?

The Brother TN450 uses the DR-420 drum unit. As a general rule, you should always change your drum unit after four consecutive TN450 cartridge replacements. The drum unit is a perishable item that can be used to print around 12,000 pages before needing to be replaced. With every Brother TN450 cartridge producing around 2,600 pages each, after the fourth toner replacement is depleted, you should get a new drum unit before your print quality starts to decrease.

How to Set Your Brother TN450 to Continue Mode?

After you receive a message to replace your toner cartridge, your Brother printer will generally stop working. Although you still need to replace your Brother toner, there is still toner left in that cartridge that can be utilized. Brother printers have a setting called Continue Mode that allows you to resume printing after you have received the Replace Toner message. Although it will resume printing, the quality may not be up to par with your previous prints. Streaks, faint color, and impressions may all be present, depending on your usage. Setting your printer to Continue Mode is a handy tip to get the most out of every TN450 toner.

For older Brother printer models that use a numerical keypad, then your procedure will have a slight variation to it. 

Step 1: Select Menu on your printer panel

Step 2: Navigate to the General Set-Up menu

Step 3: Select Replace Toner

Step 4: Select the Continue option

Step 5: Press Stop/Exit

It is important to note that this change is not permanent and will be applied until you change your cartridge. Once you have replaced your used cartridge with a compatible Brother TN450 toner, your printer will automatically revert back to its default settings and Continue Mode will no longer be enabled.
