Brother MFC-J4335DW 20 ppm Wireless INKvestment Tank All-in-One Inkjet Printer with Duplex and Fax MECH-ADF-MISFEED Error Fix: ADF Document Feeder Misfeed or Multi-Feed

Error code MECH-ADF-MISFEED on the Brother MFC-J4335DW 20 ppm Wireless INKvestment Tank All-in-One Inkjet Printer with Duplex and Fax means: ADF Document Feeder Misfeed or Multi-Feed. The Automatic Document Feeder (ADF) is not picking up documents reliably, is feeding multiple pages at once, or is skewing pages during scanning, copying, or faxing. The ADF separator pad and pickup roller wear over time and become less effective at separating individual sheets. Clean the ADF pickup roller and the separator pad with a lint-free cloth dampened with water — these are accessible by opening the ADF cover on top of the printer. If the rubber roller is shiny or hard, it may need replacement. Make sure documents are not wrinkled, Dog-eared, or stuck together. Fan the document stack before loading. Adjust the ADF paper guides snugly against the document edges. Do not exceed the ADF's maximum page capacity (typically 20 sheets).
