I spent countless hours searching those manuals over the internet.They should be free for download directly from Brother website, yet you can find them only on shady and suspicious websites asking to charge you with no shame. Hilariously, all advertise them as "free". However you can download your manuals here : Brother 1034d service/parts/user manual
.I think manual for Brother 920D is quite similar with 1034D. I hope you will find this helpful. I belive this informations should be free of charge.We have the right to own a service manual for the product we bought. :)
