Common Causes

The paper tray is not fully pushed into the printer and the sensor cannot detect it
The paper tray was removed for loading and was not put back
Something is blocking the tray from sliding all the way in — a paper clip, debris, or a bent guide
The tray detection sensor inside the printer is dirty or malfunctioning
The paper tray itself is damaged or cracked, preventing a proper fit

How to Fix It

Pull the paper tray completely out of the printer. Check that nothing is blocking the tray slot.

Look for paper scraps, paper clips, or anything that fell into the slot.
Reinsert the paper tray firmly. Push it in all the way until you feel it click into place.

The tray should sit flush with the front of the printer. If it sticks out, something is blocking it.
Make sure the paper inside the tray is loaded correctly. The stack should be flat and within the maximum fill line.

Overfilling the tray can prevent it from seating properly.
Check the paper guides inside the tray. They should be snug against the paper edges but not so tight that they bow the tray.

Misaligned guides can prevent the tray from fully inserting.
Turn the printer off and back on after reinserting the tray.

This forces the printer to recheck the tray sensor on startup.

When to Call a Professional

Error 48 rarely needs professional help. If the tray is fully inserted and the error keeps appearing, the internal sensor may be faulty. A sensor replacement costs $30 to $60 at a repair shop.

Frequently Asked Questions

My tray is in but the error will not go away. What now?

Try removing the tray and looking at the sensor area inside the printer. The sensor is usually a small plastic lever or tab that the tray pushes when inserted. Make sure it moves freely and is not stuck or broken.

Can I print from the manual feed slot instead?

Yes, most Brother printers have a manual feed slot on the back or top. You can feed paper one sheet at a time through this slot. This bypasses the tray entirely and lets you print while troubleshooting the tray issue.

Can I order a replacement paper tray?

Yes, Brother sells replacement trays for most models. Visit brother.com and search for your model number to find compatible parts. You can also find them on Amazon or office supply stores.
