The TN450 toner cartridge I recently purchased simply does not fit into my new DR420 drum unit, Am I overlooking something?

Did you buy for Brother Printer, Model HL 2280DW? I use TN 450 toner cartridge and it fits into my DR420 drum unit. It's tricky to get in, fiddle with it.

I have learned the hard way to use only Brother brand toner TN-360. It's much more expensive but I have had bad results with several different compatibles, including inferior printing, much less ink than stated, and once it just wrecked my drum entirely. You can get the toner on Amazon and sometimes Costco Online will have a deal on it.

Try gently pressing down on the top of the cartridge at the front edge. It should just click in. Ensure you are putting the cartridge in the right slot as well (I have made this eror). Dennis

I'm guessing you're looking for toner, not drums. This is the wrong product. DO NOT OPEN. Vendor will not accept returns if you open it. However, if you really need a new drum, the cyan, Magenta, & yellow are identical and interchangeable. But you probably want toner. .. search for product number TN-210M for Magenta.

Double check that you have ordered the correct cartridge for your printer model. Check that it is in the correct slot and installed firmly.

this is the toner only. the casing, or drum if you call it, only comes with the new printer. you don't need to change the casing unless it is broken, and the 420 toner doesn't come with one. it will be very expensive if it does.

Yes - I had the same issue. I did the following and got WAY more life out of them. there are sensors on the sides of the toner cartridge (it might be the drum). I covered them with black tape and then reset the toner through the menu. This video shows the reset process. https://www.youtube.com/watch?v=_Wv80u_NA_Q

did you clean the wire? Are you using the original Brother toner? If so & this is your 3rd or 4th toner cartridge & you haven't previously replaced the drum it looks like it's time to place the drum. I usually replace the drum after the 3rd toner cartridge, i.e. the toner cartridge sits inside my Brother MFC. BTW- I use mine for personal use so minimal streaking is acceptable.

Yes - the drum cartridge is separate from the toner. You do not need to replace the drum every time you replace the toner. The drum should last much longer. I have stuck with brother toner and drums as I have had issues (not necessarily with brother printers) using generic replacements.

I replaced my drum about 3 years ago for my MFC 4800. From the markings on the package I concluded it was a genuine Brother. It worked well until about 2 months ago when it started leaving grey streaks. I'm not sure if the problem is the drum unit or the toner cartridge. Note also that I only use the unit as a printer. Also, I have found that the off-brand toner cartridges leave streaks. If your using an off brand toner cartridge, you might find replacing it with a Brother cartridge will solve the problem. Good luck.

I have a new printer now so am not sure, but try unplugging both the power cord and the comm. cord to "boot" it. Leave it off for a few minutes. If that doesn't do the trick, make sure if it is locked (can't tell by your description) or whether it's just choosing the wrong tray all the time. Once in a while I actually had to resize the picture inside my photo editing software and then reprint because it kept wanting to 4 x 6 everything. (only once in a while) If I remember correctly, there are sliders inside the trays to make the paper snug. Check them and make sure they move back and forth like they're supposed to in case that might be the problem. Try moving the sliders in the larger try all the way to the outside??

I assume you know that the toner cartridge is distinct from the Drum, and that the drum lasts about 4 toner cartridges. The 1.5" patern does reflect the circumference of the toner cartridge roller (how 'bout that 2 Pi r?), so if your drum isn't old, then I'd guess you're right that it's a bad toner cartridge--I've never had one bleed, and my drum is going on 10,000 pages (well past the 8500 page rated life).

Sorry, I have not had an issue changing toner cartridges, so I'm not sure how to fix it. Did you pull all of the protective plastic tabs off of the cartridges? Try tipping the cartridge back and forth a few times to loosen the toner. One time my printer kept saying the paper was out when it wasn't. I turned off both the printer and the computer and rebooted them. That seemed to fix my problem. Sorry I can't be of more help.

My printer is different(dcp-7065). When I installed, I used the old cartridge holder and only replace the toner cartridge. There is a small paper in front of cartridge head(printing), make sure you pull it out. Thanks.

I looked up the toner spec and DCP-7065DN on the compatible list but actually, it won't work. I tried to install into my DCP-7065DN many times and it always show the message "paper jammed"

The initial unit contains both drum and toner. I couldn't get a p/n off of the toner cartridge, but extrapolating from the usage data (available on the lcd menu), I deduce it's a 2000 count cartridge. I know there are 4000 count Oki cartridges for this unit on the market, but have not done extensive research. Using a low count/starter cartridge is a standard industry practice and you would expect that in a price-competitive industry. As far as the drum, I once again calculated based on usage data and deduced that it will last about 20,000 pages. Overall, I have been quite happy with the Oki and even happier to get away from the complexity and expense of a color printer. The initial unit contains both drum and toner.

I bought mine back in Oct. 2013, it's been working great for 7 months now. I used to buy the original Brother toner which was almost $100.00, this one is a 'Brother TN350 compatible toner cartridge', I take it as a generic brand but is compatible to Brother TN350. Before you install the cartridge, make sure you shake it several times, shake it left and right plus up and down. These toner cartridges use dry powder ink, it may settle to one side during the shipping. Good luck!
