• Resolution 1
• Remove the cartridge from the printer, and locate the shipping lock lever arm mechanism (fig. 1).
• Holding the cartridge in the upright position, push the white lever forwards. This should lift the black lever (fig. 2).
• If the mechanism does not operate smoothly or is stuck, this is likely the cause of the error.
• If the mechanism is not operating smoothly, wiggle the white arm slightly and try again.
• If this does not help, tap the cartridge and vacuum or blow air into the mechanism to free any small amounts of toner lodged inside.
• 
• 
• Resolution 2
• Turn the printer off using the power button.
• Swap the affected cartridge with another colour toner cartridge in the printer. (For example: if the cyan cartridge was affected, put the cyan cartridge in the magenta slot and the magenta cartridge in the cyan slot.)
• Close the door and allow the printer to initialise.
• After a long initialisation, the printer will report the error "Supplies in wrong positions."
• Power off the printer and swap the two cartridges back to their original positions.
• Close the door and turn the printer back on.
• The machine should initialise and return to Ready mode.

• If the print quality is poor, remove the toner cartridge from the printer and gently rock the cartridge from side to side.
• This movement helps distribute the toner evenly within the cartridge.
• After rocking the cartridge 5–6 times, re-insert the cartridge into the printer and print a test page.
• If the issue persists, check the life of the maintenance items in your machine in case any of them need to be replaced.

• Remove and re-insert the cartridge.
• Check the drum (roller – green or blue) for defects, being careful not to touch this part.
• Clean the drum with a dry lint-free cloth.
• Clean the contacts on the cartridge.
• Print 5–10 pages to remove potential foreign material under the wiper blade.
• If the problem persists, install a new cartridge.

• Print out a Print Quality page.
• If the problem persists, print a cleaning page.

Print a cleaning page using the following procedure:

1. From the Home screen on the printer control panel, use the buttons or swipe until you can select the Setup menu.
2. Select the Setup icon to open the menu.
3. Open the Service menu.
4. Open the Cleaning Page icon/button.
5. Load plain letter or A4 paper when you are prompted.
6. Wait until the process is complete. Discard the page that prints.

• Remove the cartridge and re-install it.
• If the problem persists, clean the contacts on the cartridge with a dry lint-free cloth.
