I would suggest that you review the following site Phaser 6180MFP Support & Drivers for solutions.
The following is one of those solutions but there are more. Thin Image Cut Off or Deletion at Edges When Copying or Printing
This Product also has Chat available from the above site.
If that does not resolve your issue you may consider contacting our specific product support experts for customers in the USA at the following link: Fast Track to the Expert
If you are outside the USA you should contact the local support center in your area which you can find here:
