🖨️ AISEN Compatible Drum Unit Replacement for Brother DR221 DR221CL DR-221CL Drum Unit, Compatible with Brother HL-3140CW HL-3170CDW HL-3180CDW HL-3150CDN MFC-9130CW MFC-9330CDW MFC-9340CDW Printers (4 Pack) Review

I cannot say how happy I am with this cartridge. Excellent quality and no problems with the printer and software (Brother printers). I got rid of my HP printer which I couldn't use cartridges other than HP which are 10x more expensive.

I bought these because I had a lot of blue streaks on all my scans and the machine said to replace the drums - which I did - would have a new one printer for the cost and toner but I didn't want the hassle --- I followed the directions exactly - didn't solve anything and the printer is still telling me to replace the drum units!

Ordered, delivered in 24 hours. The packaging is very good, no extra space for drum hits and foam to break (foam end caps keep everything in place). Replaced original Brother drums and so far everything works fine (with original Brother toner, just haven't tried anything else). I will update if they fail. :)

Definitely does the job at a reasonable price. I didn't have these uneven production processes and the print quality has been excellent to date. I certainly think this is the most economical and ideal cartridge for printing. Easy to install and there is none of the bleeding/bumps that you can sometimes experience.

The print quality is very poor. It only gets better if I take out the toner, shake it, and "clean" the drum by moving the lever back and forth a few times. This makes it a little better, but then the print quality starts to get bad again. I've never had to do this with OEM drum blocks. This is clearly not a sustainable solution. I would not recommend them. I was trying to save a few bucks and saw good reviews here, but lesson learned.

The print quality on them is very bright. It only gets better when I take out the toner, shake and drum "clean" by moving the lever back and forth a few times.

The packaging and the product are very impressive. I have used both Aisen toner drums and laser toner and both have worked flawlessly. The colors are very intense and the drums ensure an even distribution of the toner for a new quality. It is important to note that the Brother MFC-9340CDW printer requires you to manually reset the toner drum change to display the 100% life remaining on the LED screen, whether you are using OEM or aftermarket - capacity the toner cartridge is automatically…
