Description
Compatible Models: Brother DCP-B7535DW, B7535NW.
Part Number: DOOMZH001 / B57T173-4.
What It Is: The Formatter Board / Logic Board (also called the Main PCB Board, Motherboard, MPCA or MLC) - the laser printer's central circuit board that controls the laser print engine, toner cartridge communication, and USB/network connectivity. A faulty formatter board causes the printer to appear completely dead with no lights, go unresponsive or stuck in a boot/restart loop, throw a persistent error or blinking-light fault code, or fail to be detected by the connected computer even though it powers on.
Note: this exact suffix part number (B57T173-4) is shared with this catalog's Brother DCP-B7500d formatter board listing (batch 39) - the same board evidently fits both closely related Brother models.
Condition: This listing's source description states two different stock options together - New Original with no warranty/non-returnable, OR Refurbished Original with a 30-Day Replacement Warranty.
Please confirm with us at the time of ordering which condition/warranty option is currently in stock before you purchase.
