Brother PF KIT SP D011XY001 is a paper-feed kit listed as an option part in Brother’s printer parts manual. It is identified specifically as PF KIT 1 SP, making the exact part number important when matching a replacement part to the printer’s parts list.
The manual covers printer models including DCP-L3510CDW, HL-L3290CDW, MFC-L3750CDW and MFC-L3770CDW. It lists D011XY001 separately from D011XZ001, which is described as PF KIT MP SP. This distinction helps identify the single-purpose kit in the catalogue without confusing it with the separate MP kit.
