Brother printers (MFC, DCP, HL and QL series) prints blank pages

Brother printers (MFC, DCP, HL and QL series) prints blank pages: supply installation/venting, protective seals, nozzle/printhead output and driver document content should be separated. Scoped to MFC-L3780CDW, with the other Brother laser, inkjet and label models in the model notes.

Blank pages from a Brother usually trace to supplies or a new-consumable fault. On laser models Brother's toner article says the machine has separate consumables, the toner cartridge and the drum unit, so check both are installed, that you replaced only the right one and that the toner is a brand new, unused cartridge, since a partially used or swapped cartridge stops the machine reading toner consumption correctly.

The checks in more detail

Reinstall the cartridge and drum as one assembly, making sure the orange seal or tab has been removed from a new cartridge, and check that the cartridge is seated and the front cover closed. Brother also says a dirty corona wire can cause this class of fault: slide the green corona cleaner tab back and forth a few times on the drum unit, as the machine's manual shows. If a single color is missing on a color laser, check that color's toner cartridge.

On INKvestment inkjets, print the nozzle check from the maintenance menu, clean the print head from the menu and check the ink tanks are filled and their caps closed. Check the paper is loaded print side correctly, and that the file is not blank. Print a test page from the panel to separate a machine fault from a document fault. If the machine still prints blank with new genuine supplies, contact Brother. Keep new consumables in their packaging until you fit them, and fit the toner and drum together the first time so that you know both are seated.

A quick test page after any supply change catches a blank-page fault before it wastes paper. Look at the toner cartridge and drum in daylight for a missing seal or damage before assuming the machine is at fault, and photograph what you find. If blank pages appear only when printing from one program, export the file to PDF and print that, which tells you whether the file or the machine is at fault.

  4. 4

    A dirty corona wire
