The black rollers that pull the paper through the fuser and onto the output tray are attached to a gear. The rollers broke off the gear and I'm wondering if that part is available anywhere or if an entire fuser assy needs to be purchased. Does anyone know? And if it is available solo, what is the part number?

Probably a broken Hot Roller gear in the fuser. The fuser is the section in the back, that presses the print between a pair of hot rollers to melt the powdered toner into the paper, making the image permanent. That combination of heat and pressure makes the fuser vulnerable to breakage in any laser printer or copier. The HR (hot roller) gear is a ring around one end of the heated roller, and it sometimes breaks apart. The MFC 9880 isn't listed on Brother's US service website, so I can't tell you whether you need to buy a whole fuser assembly or just that gear.
you need do follow steps:
1) check fuser unit, the fuser hot roller is hot or not? if not the fuser heater fail.
2) check hot roller should spin with the pressure roller which is against hot roller, and check there is no gap between them, and also nothing pieces paper obstruct there, because if it losts pressure balance that jam should be occured there.
3) check the output roller after fuser unit(if there is), check them are spin or not, this roller kit use for pull the paper goes out the tray. if not spin means the roller drive belt or gear loosen.
3) check paper sensor that is micro swtch around pulling roller or output area and to clean it (could be a optical sensor).
hope help you something fixed, please take a rating let me know how much helped you thanks! keep in touch your question
As i can understand whenever you try to print with rear door closed printed page should come on top from top output roller however paper gets jammed.
Try to print a page using rear door open and it should come out from the rear drop down tray it printed page comes out successfully with rear flap open than paper gets jammed at top due to faulty top output roller.
However if the paper gets jammed at fuser with rear door closed than it is issue with fuser in that case you need to get fuser replaced at the same time replace 20 tooth gear next to fuser.
Paper jams can occur in 3 places: Entry, registration and exit.
If the paper isn't picking up out of the paper tray, visually inspect the pickup roller. If it looks shiny, replace it. You should also replace the separation pad as they work together. On the 4L/4P/5P/6P the pickup roller has a plastic shaft that breaks. You'll have to replace the whole pickup assembly. This requires major disassembly of the printer. Check our printer repair kits for your model printer. If you don't see it listed, email us.
If you have an HP 4/4+/5 with an optional 500 sheet feeder that's jamming, check the balance knob adjustment. Center it with a full **** of paper for proper operation.
If the paper is jamming at registration or anywhere between pickup and exit it could be a number of things. Check the paper path for torn bits of paper or label residue. On the II/III series, remove the metal registration guide plate (2 screws) and check underneath it. If the pickup rollers are moderately worn, the paper will stop just short of the registration roller. On the 4L/4P/5P/6P remove the screw holding the oblique roller assembly (Inside front of printer) and pull out and inspect the assembly and the area under it. On the HP 4/4+/5 pivot up the metal plate and check underneath it. Check the roller assembly on the left side for torn scraps of paper (a flashlight or torch is necessary).
Make sure paper cassettes are firmly seated, corner tabs aren't bent. Some trays have lifting springs that could pop out if tray has been dropped.
Check your software settings in the program you are attempting to print from. Do you have the correct paper size specified? If you have a different paper size than what is in the tray, you'll get a paper jam.
Exit jams are frequently caused by exit sensors. These sensors are typically mounted on the fuser assembly or adjacent to it. They are plastic arms that block and unblock an optical sensor. The arms can get stuck or knocked out of place when clearing paper jams. The optical sensors can also get dirt blocking the photo cell. Clean the sensor and check for free movement and proper installation of the sensor arms.
On HP II/III series exit jams are mostly caused by worn gears. The best way to troubleshoot this is to defeat the door interlock (see door interlock photo on troubleshooting page). Press down on the arm on the top right of the fuser. Initiate a test page. While holding down the arm, press one of the metal cartridge detect switches just below the door interlock. Watch the movement of the gears. You will get a 51 error because the door is open. Recycle power to get rid of error. There is an arm gear on the lower right of the fuser that can shed teeth. There is also a 14 tooth gear below the large gear on top of the fuser. You can also manually rotate the large gear and check for binding or crunching. If that happens, then replace the 14 tooth gear. On the door, there are some delivery coupler gears that mate with the fuser and drive the exit roller. Check the gears for excessive wear. Replace if necessary. If the paper gets almost all the way out and jams, replace the exit roller or the exit roller assembly. If the error occurs after fuser replacement, check and see if the connector on the left of the fuser is properly mated with the one in the printer.
On HP 4/4+/5 printers the most common cause of exit jams is the exit assembly. Order our 4/4+/5 Exit Jam Repair Kit. Exit jams in the fuser can be caused by a broken fuser drive gear or a broken gear on the fuser. Remove the fuser and check the gear inside the printer for broken teeth. Manually turn the gears on the fuser and check for smooth operation. Check the paper exit sensor arm for proper mounting and free movement.
Check to make sure the rear door is closed on the printer. Open doors can cause 13 paper jam indications.
On the 5L/6L check the registration sensor arm below the pickup roller. Also check the exit sensor arm (bottom center of the fuser). These arms frequently get stuck or dislodged clearing paper jams. On these printers, if you are experiencing frequent paper jams, order our 5L/6L Multi-Sheet/No Feed Repair Kit
First thing to try is to flip the paper over in the input tray. There are 2 sides to paper. One side may curl a bit too much due to heat of the fuser and get caught near the output rollers.
Unless the Output Assembly was assembled wrong, it is impossible for the rollers to turn the wrong way. The gear in the fuser drives the output assembly. The top rollers are rolling out.
If the rollers are not rolling, then one of the gears must be broken or missing. The output rolllers might need cleaning.
Next check the fuser unit. Disconnect power to printer and turn printer round. Remove the back output tray and the two small covers (left and right). Undo the 2 screws that hold the fuser in place. Pull the fuser out. Check the gears on side of the fuser. A broken gear in the fuser could cause this problem.
hi im jules_09,there must be a small piece of paper stocked at the
output tray.see if you can open the front door then full out the fusing
unit somtimes paper is stocked in it.then while the fuser or fusing
unit is out check the output tray if there is a paper.in the fuser unit
check the hotroller or upper roller its a black metal roller that
