Risk level
Low
Usually safe to check without specialist tools.
Urgency
Medium
Quick answer
On Brother MFC-T920DW, MFC-T925DW inkjet printers, a Jam B Front or Repeat Jam B Front message means paper is jammed in the front of the machine. Unplug the printer, remove the paper tray completely, and pull the two green levers inside.
Safety first
Stop and check this first
- Always unplug the machine from the electrical socket before reaching inside the front tray cavity or pulling the green release levers.
- Pull jammed paper out slowly so it does not tear and leave scraps inside that trigger Repeat Jam B Front.
Safe checks you can perform
- Remove the paper tray and pull the two green levers to extract the front sheet
- Look carefully for scraps and open the rear Jam Clear Cover for Repeat Jam B Front
- Clean the paper pick-up rollers with water and check the tray position for A5 media
Leave these tasks to a qualified professional
- Do not attempt this professional task: Brother Authorised Service Centre if Repeat Jam B Front does not clear
- Do not attempt this professional task: Pick-up assembly service if sheets keep jamming at the front entrance

What they doWhen sheets repeatedly stall in the front feed area even after cleaning the paper pick-up rollers with a water-moistened lint-free cloth and keeping the tray unextended for A5 media, have Brother service inspect the pick-up mechanism.

Remove the paper tray and pull the two green levers to extract the front sheet
- Who:
- you, after transferring any stored faxes in memory and unplugging the machine from the electrical socket.
- How:
- pull the paper tray completely out of the machine, pull the two green levers inside the machine to release the jammed sheet, and slowly pull the jammed paper out through the front tray opening.
- Result that matters:
- removing the jammed sheet from the front feed path without tearing it.
- If the LCD message was Jam B Front and the sheet came out intact:
- refit the tray, unfold the paper support flap, and reconnect power.
- If the LCD message was Repeat Jam B Front or the sheet tore:
- follow the additional steps to check for scraps and open the rear cover.
- Evidence to keep:
- the removed sheet checked to confirm no torn corners were left behind.

Look carefully for scraps and open the rear Jam Clear Cover for Repeat Jam B Front
- Who:

- Result that matters:
- clearing both hidden paper scraps in the front cavity and any sheet caught in the rear path.
- If the message clears once the power cord is reconnected:
- the repeat jam is resolved.
- If sheets continue to jam when feeding from the tray:

Clean the paper pick-up rollers with water and check the tray position for A5 media
- Who:
- you, with the printer unplugged from the electrical socket and the paper tray removed.
- How:
- wipe the paper pick-up rollers with a soft lint-free cloth moistened with water while slowly turning the rollers to clean the entire surface, wipe them dry with a dry soft lint-free cloth, and make sure the paper tray is not extended when loading A5 or smaller paper.
- Result that matters:
- restoring roller grip so sheets feed cleanly into the front path.
- If pages feed smoothly after cleaning the rollers:
- paper dust on the pick-up rollers caused the jam.
- If Jam B Front or Repeat Jam B Front stays on the display with no paper inside:
- contact Brother service.
- Evidence to keep:
- confirmation that the pick-up rollers were wiped dry before pushing the tray back in.

What it means
According to the official Brother Online User's Guide for the MFC-T920DW and MFC-T925DW, the LCD displays Jam B Front when a sheet stops in the front paper feed area. If paper scraps remain inside or the jam is not cleared completely, the display changes to Repeat Jam B Front. Other Brother models may display different jam codes, and this message alone never proves that a paper feed motor or sensor has failed.
