I just cleaned the fuser unit on my AL-1642CS printer, which fixed a major problem I was having. However, I now have a paper jam error. Is there a sensor in the fuser unit that I might have disrupted while cleaning? If so, where? Where are the paper sensors located in the rest of the machine?

This copier has 4 sensor 1. paper sensor It is called paper sensor its installed paper tray 2.Drawer sensor 3. Drive sensor its installed middle position 4. Exit sensor it is in fuser unite. May be any sensor displace or broken.So you should check it. Good luck.
The fuser has a flag sensor with an arm that the paper hits as it passes through. That arm moves a flag at the other end that hits a photointerrupter. You may have broke this. If so, you will likely need to order it through a dealer.
(For Laser Printers Only) Toner sediment in the fuser unit. This specially occurs if you constantly use smaller paper sizes than the paper tray size. To resolve this you should disassemble the printer, take out the fuser unit and clean the toner sediment. The sediment can get rock solid so clean it carefully. If you are not accustomed with electronic components better visit a technician.
The paper sensors pulling spring may be detached. In this case the sensor gets a message that some paper exists in the fuser unit so a paper jam message is triggered. Fix the spring and you are done.
there is a set of stripper fingers that kiss the fuser roller and paper is jamming up aginst that area
Open the fuser section door and front door Look at the fuser roller from exit and front door If there is a wiper pad (slides in on a rod from the side of the machine) remove it and put some fuser oil on it
go to area where you find the paper folding up and observe the stripper fingers for any blockage
If there is some bits of toner on the fingers clean them with a q tip and alcohol
take your finger ( make sure machine has cooled and you have unplugged from wall) and press up against the stripper fingers to se if there is movement (some coiers have a solenoid that activates the striper fingers)
The fuser oil hels keep the fuser roller clean and keeps paper from sticking on rollers
Try the copier if this does not fix i believe you have a problem with a solenoid which will require a sevice call
If you want to observe the paper coming through the fuser rollers and seeing if the fingers activate ou can trip the safety swithes in the doors and exits and observe
Loud clacking sound, jamming in fuser ? sounds like the gear that turns the fuser are bad and not meshing together,
accordion jam is the fingers or claws that ride on the fuser roller are probably worn out ( these can be replaced usually 3-5 ).
You can buy the parts and replace them yourself if a handy person, not that difficult.
Where is it saying the paper jam is located? Do you have a service code?
It sounds as if either a paper pass switch is stuck in the down position (meaning it thinks there's a piece of paper there), or you may have a sheet of paper stuck in the fuser or behind a guide plate. Check on these and let me know!
