The machine cannot be operated and the error code <E000012> appears on the display.

Cause and Solution

The delivery feeder unit may not be installed correctly. Follow the procedure below to install the delivery feeder unit correctly. If the error code persists after the delivery feeder unit is installed correctly, contact your local authorized Canon dealer.

Re-install the Delivery Feeder Unit
NOTE
  • You have to remove the delivery feeder unit and reinstall the delivery feeder unit correctly.
  • When you remove the delivery feeder unit, you have to turn the main power switch OFF.
  • Sending or receiving documents cannot be done when the main power switch is OFF or the power cord is disconnected.
  • If the main power switch is turned OFF, all jobs waiting in the print queue will be erased.
  • Documents received into memory and documents stored for delayed send will be retained for approximately 60 minutes after the power cord has been disconnected.

1. Turn OFF the main power switch and disconnect the power cord.

2. Open the front cover.

If you are using the stack bypass tray, close it before opening the front cover. Open the front cover gently holding the handle (A).



3. Push the levers (A) on both sides of the delivery feeder unit and remove the delivery feeder unit gently, holding it by the tabs (B).




CAUTION
Do not place any object on or touch the transfer belt (A) of the delivery feeder unit. You do not need to manually clean the transfer belt even when it is stained by toner, as the delivery feeder unit has a self cleaning function for the belt. Breaking the delivery feeder unit or damaging the transfer belt may result in misfeeds or deterioration in print quality.
4. Install the delivery feeder unit so that the protrusions (A) of the delivery feeder unit fit into the guides (B) and click into place.



5. Confirm that the triangle marks (A) on the delivery feeder unit are aligned with the triangle marks (B) on the machine.



6. Close the front cover.

Close the front cover gently holding the handle.




CAUTION
Be careful not to get your fingers caught.
7. Reconnect the power cord and turn on the main power switch.

If the error code persists after the delivery feeder unit is installed correctly, contact your local authorized Canon dealer.

"remove original from document processor"


Sensor in feeder is probably broken. To get around this until you can get it fixed power down the unit and unplug it. Unplug the cable that connects the Doc feeder (in the back) to the main unit (two screws hold it on. Then power the unit back up it will work with out the Doc feeder. You will just have to put the copies on the main glass.

Wat is an LSU error on a phaser 3200 MFP


Change the toner cartridge , i have many units phaser3200 and this is one of the problem , but only if the toner cartridge is very old and many time refilled , if not , change the Laser unit .

  1. Remove a misfed document if the copier displays a message reading "Document Jam." Lift up the document feeder cover and turn the roller to remove an Exit Misfed document. Lower the document feeder back into place and feed the document through again. If the document is jammed on the Input side, open the cover and gently pull the misfed document to the right and out of the feeder.
  2. Pull out the paper tray and lift the tray to release it from the copier if the copier displays a message reading "Paper Jam O." Remove the jammed document, and open and close the side panel of the copier to clear the error message.
  3. Unplug the power cord and plug it back in again if the copier displays a message reading "Fuser Error, Open Heat Error, Heating Error and Overheat." If the problem persists, call for a service.
  4. Remove the toner cartridge and shake it from side to side if the copier displays a message reading "No Developer Cartridge." If this does not do the trick, you may need to replace the cartridge. Pull the release latch to open the side cover, and open the front cover. Twist the cartridge locking-lever upwards and remove the toner cartridge. Insert the new cartridge and lock the lever into place. Shut the front cover and the side cover.
  5. Power off the unit and power it on again if the copier displays a message reading "LSU Error." A problem has occurred with the Laser Scanning Unit. If the problem persists, call for a service.

Dust on drum error message. How to clear


On most fax machines a Dust on Drum error simply means that the drum unit needs to be removed and the charger cleaned by sliding the small built in charger cleaner back and forth but be sure to place it back in it's home position or your received faxes and copies will have a blank line thru them. See your operators guide for more details.

Ricoh Aficio 2035G Duplex issue


When you open the whole duplex unit you will see a very small metal tab with a screw, on the top right side on the machine. This activates the switch on the duplex unit.
Or with the duplex unit open you will se a small rectangle hole inside a switch, put a piece of paper or something to activate it, might got stuck.
This problem is very common on this machines.
