Transfer roller

1. Open the printer control panel cover and front door.



2. Remove the toner cartridge bottle and imaging unit.



3. Using the drive gear, gently pull the right-hand side of the transfer roller to slightly detach it from the machine.

   • Gently move the transfer roller rightward to disengage it from the left transfer roller arm.



4. Unpack the new transfer roller kit from the package but do not remove the protective plastic covering the foam surface.

   Note:  When installing the new transfer roller, avoid all contact with the foam surface, or print quality issues could result.



5. Insert the transfer roller starting on the left side and then on the right. A clicking sound indicates that the transfer roller has been locked in place.



6. Slowly pull to remove the protective plastic.



7. Insert the imaging unit and then the toner cartridge.

Pick roller assembly

1. Pull the media tray out from the printer until you meet resistance.



2. Lift the tray and remove it from the printer.



3. Lower the front duplex flap to gain access to the pick roller assembly.



4. Squeeze both sides of the pick roller latch, and move the pick roller assembly rightward to remove it.



5. To install the pick roller assembly and the paper flag down out of the way. This is especially important on input options because less room exists in this area.

   Notes:

   • When installing the pick roller assembly, avoid all contact with the roller surfaces, or paper jams could result.
   • Failure to keep the flag out of the way while installing could result in the flag being broken off or trapped under the pick assembly, and the printer will not pick paper properly.

2. Press the button to release the separator roller from the tray.
