We get a paper jam error when no there is no jam. I have opened the fuser and the paper has advanced about half way through the unit but appears clear.
I suspect that this is a sensor problem, but I don't know what the sensor looks like. Is it mechanical or electronic. If I remove the fuser unit, there is a black, plactic arm which presently swings free and doesn't appear to be attached to anything. I have opened up the bottom, removed the front circuit board, but still cannot see anything that this arm would connect to.
Are schematics or photos of the insides avaialble anywhere? I am in Costa Rica and have no access to a Brother Serv ice center. (I do computer repairs).

If you have a spare Fuser Unit I would suspect you install that and try it.
Have you had a jam in the fuser in the past in which case check the paper sensors are working correctly by activating them with a sliver of paper.
I have known the exit sensor to be jammed and only when you remove the exit transfer unit to the finisher will it be obvious.
If that is a but daunting then you might need to call in Xerox.
The fuser sensor may look ok, but if you pull off the back cover and study closer, you may find that the lower half of the right toggle sensor is broken, leading the sensor to "think" that is is stuck in the open postition. As a temporary fix, unplug that sensor from the fuser board. Ultimately you will have to replace that switch, and that is a hard part to find unless you replace the fuser unit.
-922 Fuser Error messages indicate that the fuser unit failed to reach the standby temperature.
If this is the first time you have seen the error, turn the printer off and on.
-Leave the printer off for at least 10 seconds before turning it back on. This gives the printer's engine board a chance to reset. If this is an intermittent error, you may want to check how the printer is plugged in, even if it has worked on this surge device for months. Make sure the printer is plugged straight to the wall and not through a surge device or power strip. Power strips and uninterrupted power supplies can cause a low amperage problem in your printer which can trigger a false fuser error. If this does not help or if this error appears every time the printer is powered on, you will probably need service on the machine.
- 923 Fuser Error indicates that the fuser unit is getting too hot while printing or when the printer is idle. Make sure that nothing is stuck inside the fuser unit that can cause the fuser unit to overheat. To check for any stuck sheets of paper in the fuser unit: Locate the rear door and open it. The rear door opens and drops down towards you. Look into the back of the printer. See if there is any paper or any other item stuck there that could be causing the fuser unit to overheat. If you cannot find anything jammed up or broken in the back of the printer, open the upper front cover of the printer and remove the toner cartridge. Look into the printer from the front. See if you can see anything jammed into the back area of the printer. If nothing appears to be jammed in the printer, the fuser unit or the main power supply of the printer will probably need to be replaced to fix this problem.
This error comes when media doesn't come to fuser delivery sencor with in the specified time it may be due to improper paper picking or fault in registration ***...
clean the paper feed rooler & registration *** path ur problem will resolve defin...........
Open the Top Half of the Copier. The Scanner Section pops open by pushing up.
Underneath the Scanner Section is the Fuser Unit. Check in the Fuser Section, you will find paper Jam in the Fuser Section.
Toner complaint may also cause paper jams. It can be solved only by replacing it. When you switch on the loop back plug in, two flash lights appear; then it indicates paper jam. The oil spillage in toner can cause this problem. If the toner cartridge is not functioning properly, the same problem would be the result. The diodes or transistors in the fuser unit of the Multi Function Printer may get damaged and this can lead to fuser complaints. To solve this problem, you should replace it.
Usually there is a sensor right before the paper enters the fuser. If the paper sensor is bad the machine will stop feeding and output the error paper jam. This is probably the cuase if the paper stops in the same position all the time.
