I have a Canon S830D printer that no longer prints. The paper goes in halfway then stops and I get a rapid clicking sound then the message appears that there is a paper jam.. I have used the Cleaning the print head mode, Refreshing the print head mode and Printing a nozzle check pattern, but the copier still won't print. Is this printer ready for the dump?d

I have just had the same problem on one of these Canon MF4150 machines.
The manufactures warranty on our machine had expired just one week before this happened so I had to fix this myself.
The problem we had (which is very likely to be the same cause as yours) is when we removed some torn jammed paper, it had somehow pulled off a spring from inside the machine. The spring was linked to the paper jam sensor.
It does involve a LOT of work to fix it, and unless you are very 'techy' it may be quite a difficult task to do this for the 'average' person.
I had to completely disassemble the machine: Take off the front first (lift up the cover and there is 2 screws at the front and 2 clips on the bottom of the machine) Then remove the 2sides and finally the top (screws should be easy to see, to get the sides off, un-clip along the front edges and gently move them outwards and slide them backwards to release the clips on the back) being careful with the wires going to the scanner part). Then look for the fuser unit which is near the top at the back, there is a black rounded cover over the fuser. To remove the cover, look for 2 small clips one at each side and unclip the cover and gently lift upwards.  Under the cover on the left side you will see a small plastic rod which goes from the left side to a small tab in the middle, if you look about half way along that rod you should see a tiny spring, make sure this is clipped on properly and that you are able to rotate the rod and it should spring back to the proper position when you let go.
Once this is done, put it all back together again and it should work fine.

I'm sure a lot of other people probably have this same problem too so I hope this helps someone.

Try below some steps which might help you resolve the problem.

Print Head Cleaning / Head Refreshing If the printed Nozzle Check Pattern is broken, missing, or a specific color is not printed, clean the print head.

1. Press the <Menu> button on the printers operation panel repeatedly until [MAINTENANCE] appears in the LCD.
   
2. Press the left [<] or right [>] arrow buttons to select the cleaning setting you want. Select [HEAD CLEANING] or [HEAD REFRESHING] for deep print head cleaning.
   
   Note: [HEAD REFRESHING] uses more ink than [HEAD CLEANING], so perform [HEAD REFRESHING] only when necessary.
   
3. Press the <OK> button.
   
4. Print a Nozzle Check Pattern and perform at least two Head Refreshings if the pattern is not correct.
   

1. Press the Open Button (1) to open the Paper Output Tray (2).
   
   
   
2. Raise the Scanning Unit until it stops.

It will need a new printhead, QY6-0062-000, around $80.00. Leaving it sit and not printing just makes the problem worse, as more nozzles on the printhead get plugged. You get 90 day warranty with refurbished units and if it started out crappy you should have had a shop look at it, that model can print super photos! A new printhead will bring it back to life.
