## Description

Bu100cl Belt Unit For Suplhl4040cn/4070cdw Mfc9440cn/9840cdw

Review: Perfect fit - solved the printer issue. - I was happy to find that desertcart had the lowest price on this OEM Brother belt unit. The replacement was easy and took about 5 minutes with the included instructions. Once I closed up the printer and started printing again everything worked perfect. Two things to be aware of when changing the belt unit: 1. Take a can of compressed air and blow out the dust and toner residue from the interior of the printer, and 2. Make sure you follow the instructions to reset the END OF LIFE message for the belt unit as it does not disappear on its own, but that is printer related and has nothing to do with this purchase (just some advice).
Review: Necessary part to change; easy to buy and easy to install - A broken belt unit can lead to bit of a clean-up job inside your printer, so replacing the belt unit is for peace. Changing the belt unit in the Brother duplexing color laser model HL4040CDN simple. With the power switched to "Off", open the front of the printer as if changing toner. Slide out the drum unit until it stops. Remove the drum unit and set it on a clean paper on a table top. Lift the old belt unit out. It lifts from this green tab at the front of the belt unit. It weighs only a couple of pounds so it is easy to lift up and out from the printer. Replacing is the reverse of the process. Note: If you are changing out the excess toner box, it sits right below the belt unit, and that is just one more step to replace. I changed out the excess toner box while changing out my belt unit because it was about due, too. Afterwards the instructions walked me through the procedure to reset the belt unit counter via the on-printer menu. The procedure took 9 minutes in total to change both. The price is about $25 less via desertcart--delivered--than it is to buy in the local Office Depot. UPDATE 11/6/2013 We have gone 37,000 pages printed thus far in two years. We are on the original drum. There is no toning, and no dots or streaks appearing on the image. The drum is behaving well thus far. desertcart's ordering process was easy. Order processing was by the next day. And delivery took 2 days--to Hawaii. And we had selected Super Saver Shipping which was free. 21 months later and we are being advised by the printer to change the belt unit again. $94 is steep; however, having read of several other experiences with broken belt units it is perhaps wise to change it. I've managed to stretch my usage by about 30,000 pages. That might be worth considering. While toner costs are strictly 1.5 cents per page in our use, the ancillary costs are adding up. So while ink printing may be more expensive; those new HP full page width ink cartridges can become cost-competitive since inkjet printers have far fewer parts of wear as compared to their laser counterparts. Your mileage may vary.

### ⭐⭐⭐⭐⭐ When it's needed, it's worth having!
*by D***Y on May 26, 2013*

My Brother MFC9840CDW printer started flashing the error message that this unit needed replacing, so I ordered it. But knowing that many printer companies (HP, Brother among them) base such error messages purely on page count and never on actual need, I have held off from installing it. It's been 3 months now, and still my printer is working very well with the original belt unit in place. I consider my printer use to be medium, I use it in my home office and I would say my average monthly page count is between 300 and 600 each month, so if your printer usage is like mine, buy this unit when the printer starts to flash the error message but don't install it until you absolutely have to.
