Open

Power Switch

The main power switch for the printer is located on the right side of the printer behind a small clear door. When power cycling the printer, please follow the on-screen instructions when toggling the switch. The printer can take up to 5 minutes to boot, do not toggle the power switch during printer startup.

Open

Checking Toner Supply Levels

To check the current Toner Supply Levels, tap on the Status Monitor button in the bottom-left corner of the screen after logging into the screen on the Printer. Tap then on the Consumables/Others tab toward the top-right to display Toner Levels as well as Paper Tray configurations.

Toner and Drum Locations

1. Open the large front Canon door of the printer by placing your hands in the grooves on either side and pulling the door outward. The door is held by magnetic latches.
   
   

2. You will be instructed on the copier’s screen with a video showing how to remove and insert the new toners and drums when they need replacing. Do not replace until instructed so by the printer’s screen.

3. The top four circular tubes are the toners. To remove the toner that needs replacing, pull the tube outward from the printer.
   
   

4. On the new one, note the end of the toner and how it aligns with the opening on the printer.
   
   

5. The toner can only be installed one way. Insert the toner completely and close the front door. The printer screen will indicate if there are any issues with the replacement.
   
   

Waste Toner Cartridge

The screen on the printer will indicate when it is time to change the Toner Waster Cartridge. Do not replace until instructed by the printer screen.

1. Open the small door to the left of Tray 1 on front of the printer.
   
   

2. Remove the filled waste cartridge by pulling straight out from the printer and insert the new empty one and make sure the front door is able to close fully. Toner Waste Cartridges should be recycled like empty toner cartridges.
   
   

Staple Cartridge Refill

The screen on the printer will indicate when the Staple Cartridge is empty.

1. Open the small door on front left side of the printer. The staple cartridge will automatically move into a position it can be removed.
   
   

2. Pull gently on the green tab and the cartridge should eject.
   
   

3. Lift the empty clear cartridge from the cartridge holder and replace with a loaded one.
   
   

    

4. Insert the staple cartridge holder back in. You will need to push gently until the cartridge is fully inserted. When closing the door, if the cartridge holder is not inserted properly the printer screen will indicate the error.
