Description

Removing obstructions, foreign objects and paper jams from the printer.

 

Solution

 

 Important

  • The power cannot be turned off while the machine is sending or receiving a fax, or when the received fax or the unsent fax are stored in the machine's memory. Make sure if the machine completed sending or receiving all the faxes before disconnecting the power cord. If you unplug the power cord, all the faxes stored in the machine's memory are deleted.

 Note
  • If you need to turn off the machine to remove jammed paper during printing, press the Stop button to cancel print jobs before turning off the machine.

Paper Is Jammed in the Paper Output Slot or the Rear Tray

 

Remove the paper following the procedure below.
 
  1. Slowly pull the paper out, either from the Rear Tray or from the Paper Output Slot, whichever is easier.

 Note
  • If the paper tears and a piece remains inside the machine, turn the machine off, open the Scanning Unit (Cover), and remove the paper.
     
  • Be careful not to touch the components inside the machine.
     
  • After removing all paper, close the Scanning Unit (Cover), and turn the machine back on.
     
  • If you cannot pull the paper out, turn the machine off and turn it back on. The paper may be ejected automatically.
 
 
  1. Reload the paper, and press the OK button on the machine.
    If you turned off the machine in step 1, all print jobs in the queue are canceled. Reprint if necessary.

 Note
  • When reloading the paper, confirm that you are using the paper suited for printing and are loading it correctly.
     
  • We recommend you use paper other than A5 sized one to print documents with photos or graphics; otherwise, the printout may curl and cause paper exit jams.
 

In Other Cases

Make sure of the following:
 

  • Check 1: Are there any foreign objects around the Paper Output Slot?
     
  • Check 2: Are there any foreign objects in the Rear Tray?



    If there are any foreign objects in the Rear Tray, be sure to turn off the machine, unplug it from the power supply, then remove the foreign object.


     
  • Check 3: Is the paper curled?


If you cannot remove the paper or the paper tears inside the machine, or if the paper jam error continues after removing the paper, the printer will require servicing.
