Help can often be found in the Xerox Online Support Assistant here on Xerox.com. The knowledge base articles contain step by step instructions, many with color photos, to help resolve all sorts of problems. I have included a link below to the Phaser 7300 Knowledge Base. This Knowledge Base has an automated troubleshooting program that you can use or you can troubleshoot your machine manually by clicking on the "Start Troubleshooting" link. Either of these tools should be able to help you figure out why your machine is printing incorrectly.
If, for some reason, you are not able to resolve the issue, please contact Xerox Customer Technical Support for Phasers at 1.800.835.6100.
