Brother Inkjet Jam C Rear error: clearing back paper jams
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Medium
Quick answer
On Brother inkjet printers such as the MFC-T920DW, MFC-T925DW, a Jam C Rear message indicates that a sheet is jammed in the back of the machine. You can clear it by unplugging the printer, removing the paper tray, and opening the rear Jam Clear Cover.
Safety first
Stop and check this first
- Always unplug the machine from the electrical socket before removing the tray, pulling the green levers, or opening the rear Jam Clear Cover (transfer stored faxes first if needed).
- Do not extend the paper tray when loading A5 or smaller size paper, as Brother notes this causes rear paper jams.
Safe checks you can perform
- Unplug the machine, pull the paper tray out, and release the two green levers
- Open the rear Jam Clear Cover, remove the jammed sheet, and refit the tray
- Clean the paper pick-up rollers and keep the tray unextended for A5 or smaller media
Leave these tasks to a qualified professional
- Do not attempt this professional task: Brother service inspection if Jam C Rear stays with no paper inside
- Do not attempt this professional task: Roller service if sheets keep misfeeding after water cleaning
What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Brother service inspection if Jam C Rear stays with no paper inside
What they doIf you have pulled the two green levers inside the tray opening, opened the rear Jam Clear Cover, removed the entire sheet without tearing it, and Jam C Rear still displays after reconnecting power, contact a Brother Authorised Service Centre.
They must show youthe clear front tray cavity with the green levers, the open rear Jam Clear Cover with no paper, and the persistent Jam C Rear LCD message.
In writingwhich rear paper sensor or cover latch was serviced and the repair case reference.
Roller service if sheets keep misfeeding after water cleaning
What they doWhen standard A4 or Letter paper continues to jam in the rear path even after cleaning the paper pick-up rollers with a water-moistened lint-free cloth, have Brother service inspect the feed rollers.
They must show youhow sheets hesitate or skew when feeding from the tray after the pick-up rollers were cleaned.
In writingthe condition of the paper pick-up and feed rollers and any parts replaced.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Unplug the machine, pull the paper tray out, and release the two green levers
- Who:
- you, after transferring any stored faxes from memory on MFC-T920DW or MFC-T925DW models.
- How:
- unplug the machine from the electrical socket, pull the paper tray completely out of the machine, and pull the two green levers inside the machine to release the jammed paper (depending on the paper size, it may be easier to remove it from the front).
- Result that matters:
- releasing roller tension on the jammed sheet before pulling it out.
- If the sheet slides out intact from the front opening after pulling the green levers:
- still check the rear cover before reassembling.
- If the sheet is held in the rear turn-around path:
- proceed to open the rear Jam Clear Cover.
- Evidence to keep:
- checking that the removed sheet has all four corners intact with no torn pieces missing.

Open the rear Jam Clear Cover, remove the jammed sheet, and refit the tray
- Who:
- you, at the back of the unplugged Brother printer.
- How:
- squeeze both levers at the back of the machine to open the Jam Clear Cover, slowly pull the jammed paper out, close the Jam Clear Cover completely, put the paper tray firmly back in, pull out the paper support until it locks and unfold the paper support flap, then reconnect the power cord.
- Result that matters:
- clearing the rear paper path and latching the rear Jam Clear Cover shut.
- If the Jam C Rear message clears once power is reconnected:
- the rear paper path is clear.
- If the error returns or sheets jam again on the next job:
- clean the paper pick-up rollers and check the tray extension.
- Evidence to keep:
- a photo showing the rear Jam Clear Cover fully closed and flush with the back casing.

Clean the paper pick-up rollers and keep the tray unextended for A5 or smaller media
- Who:
- you, with the machine unplugged and a soft lint-free cloth moistened with water.
- How:
- with the paper tray removed, clean the paper pick-up rollers with a soft lint-free cloth moistened with water while slowly turning the rollers so the whole surface is cleaned, wipe them dry with a dry soft lint-free cloth, and make sure you do not extend the tray when loading A5 or smaller paper.
- Result that matters:
- removing paper dust from the pick-up rollers and preventing short-media rear jams.
- If subsequent pages feed cleanly without jamming:
- roller dust or tray extension was the cause.
- If Jam C Rear continues to display with no paper inside:
- contact Brother service to inspect the rear sensor.
- Evidence to keep:
- confirming the pick-up rollers were wiped dry with a lint-free cloth before reinserting the tray.

What it means
According to the Brother Online User's Guide for the MFC-T920DW and MFC-T925DW, the LCD displays Jam C Rear when paper stops in the rear paper path of the machine. Other Brother models may use different jam location messages, and seeing this code alone never proves that a feed roller or paper sensor is permanently damaged.
