Toner dumps all over the inside, paper coated all black and jams behind fuser
This started suddenly after a serious jam in the fuser unit which had lost one of the four little paper guides. The soft roller got damaged too, so I put in a new fuser unit, now the paper jams under the ramp area where the cartridge fits, and the same problem occurs with the toner. It just dumps all over the inside, the green drum is covered in toner. This is with the old cartridge and with a new cartridge, too. I don't think the paper is feeding the right path. Could it be the transfer roller? Does the paper pass through the cartridge itself? Or just underneath it between the rollers?
Re: toner dumps all over the inside, paper coated all...
We to have this issue with one of our 1600's. I tried to resolve this by replacing the fuser with a new one. Haven't got back around to trying to resolve this as it such a mess to get started. Someone resolve this issue yet?

Causes for paper jams in Printers are given below:
* Dust or debris * Rotating drum problem * Toner or fuser complaint
Dust or debris
One of the main causes for paper jams is the presence of dirt, dust, or debris in your toner cartridge. The paper coming into the cartridge would get stuck. So clean your printer regularly. Remove the dust from the printer. Also find out whether any jams occurred in the sensor hole in the upper part of the rotating drum. Do not touch the roller while cleaning. If the oil in your body gets into the roller, the printing media cannot roll over it properly and you can't get rid of the printer problem.
Rotating drum problem
If there is no direct symptom of paper jam and still you cannot do printing properly, find whether it is because of drum problem. If the paper gets into the end gear of the rotating drum and gets stuck there, you cannot access the printing function. Switch off your printer and check the plastic arms of the printer drum. If there is any paper piece jammed in any of the arms, you can't continue printing. Here also cleaning is the best method to solve the problem. While cleaning, check the arms of the rotating drum.
Toner or fuser complaint
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 printer may get damaged and this can lead to fuser complaints. To solve this problem, you should replace it.
Clear the jammed paper as follows. Observe Cautions signs in printer.
Always remove all paper from the paper tray and straighten the stack when you add new paper. This helps prevent multiple sheets of paper from feeding through the printer at one time and prevents paper jams. 1.Press the cover release button and then open the front cover. 2.Slowly take out the drum unit and toner cartridge assembly. The jammed paper will be pulled out with the drum unit and toner cartridge assembly. 3.Pull the paper tray completely out of the printer. 4.Close the front cover. 5.Pull the jammed paper up and out of the printer. 6.Open the front cover again. 7.Open the back cover. 8.Pull the tabs at the left and right hand sides toward you to open the fuser cover (1). 9.Using both hands, gently pull the jammed paper out of the fuser unit. 10.Close the back cover. 11.Pull the duplex tray completely out of the printer. 12.Pull the the jammed paper out of the printer or the duplex tray. Put the duplex tray back in the printer. 13.Push down the blue lock lever and take the toner cartridge out of the drum unit. Clear the jammed paper if there is any inside the drum unit. 14.Put the toner cartridge back into the drum unit until you hear it lock into place. If you put the cartridge in properly, the blue lock lever will lift automatically. 15.Put the drum unit and toner cartridge assembly back in the printer. 16.Put the paper tray firmly back in the printer. 17.Close the front cover. 18.Make sure that the Paper LED is now off and the printer is ready.
After clearing paper jam if noise persist printer may need a Repair Tech and parts replacement for broken or wore parts.
This jamming has to do with third-party toner cartridges being used. I had this problem using Xerox toner cartridges and found that I would have no jamming if I used at least 2 hp-brand toner cartridges and the rest Xerox. I then used a different brand of 3rd party toner cartridges that would not jam as long as just the black cartridge was a genuine HP black toner cartridge. This issue has been confirmed even by the manufacturers of the generic toner cartridges. Hope that helps!
The fusing unit heat roller is damaged or worn out and it needs to be replaced.The roller has non-sticking teflon coating.When this coating is bad,toner start sticking to it and causing jams and bad copy quality.
If you are getting jams in the fuser or right after it the fuser is probly bad. I think there is a mylar upgrade that attaches to the toner sensor arms under the top cover(not an easy fix). It is also possible the drum unit or the toner cartridge could be bad.
Hi usually paper jam at paper input area a or transfor section(photo drum area or fuser unit area, so you may try:
1) take out paper tray and open the cover that you can change toner cartridge there (see manual) looking for any paper inside paper input area or around the cartridge, then take out jam paper.
2) open fuser unit at paper output area ckick a locker at somewhere (see maanual) looking for any paper jam
To clear this error:
Power the printer off and let it stand for at least 30 minutes to allow the fuser to cool.
Remove the coating roller from the top of the fuser unit to reveal the orange fuser rollers underneath.
Check to see if any paper/transparency has become wrapped around the fuser rollers or jammed in or above the fuser unit itself.
Since some paper jams can be very difficult to see with the fuser installed, remove the fuser and check for paper/transparency jams under the unit as well. A jam in that area can cause 993 errors.
If there is no media jam and the error remains after the printer is restarted, try replacing the Oil Coating Roller (OCR). The OCR comes with the black toner cartridge. (It can also be purchased separately. Click here to do so.)
If the error remains after the OCR has been replaced. If that does not help I would highly recommend taking it back to the place you bought it from
