Review on 🔄 Brother BU-100CL Belt Unit: The Perfect Replacement for HL-4040CN and HL-4070CDW Series - Retail Packaging by Keith Baker

My Brother MFC9840CDW printer started flashing an error message saying this unit needs to be replaced so I ordered it. But knowing that many printer manufacturers (eg HP, Brother) base such error messages only on the number of pages and not on the actual need, I decided not to install it. It's been 3 months now and my printer is still working very well with the original belt. I think I use my printer on average, 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 you use the printer like me, buy this device when you use the printer starts to work. Flag the error message, but don't install it unless absolutely necessary.
