You need to run the eliminate light stripes. it should be in the menu, under troubleshooting, print quality issues. you can run this up to 3 times. you want the run the basic light stripes, not the advanced. If after 3 times running this, you are still missing jets, your printhead is bad. If you are using aftermarket ink, media sciences might cover the repair, if not, the printhead costs as much as a new machine. about $650+labor.

I was having the same problem. Turns out the IP address in the printer was incorrect. Once I changed the IP address the printer works just fine through our network again. Find your IP address off your server and follow these steps:

1. Choose Info on display menu, press okay button
2. Choose Info pages, press okay
3. Configuration pages-printer info, press okay
4. IP address should read: Correct IP Address number should be displayed on screen.

If not follow these steps to change it:

1. Find printer setup on display menu, press okay
2. Go to connection setup-press okay
3. Network setup-press okay
4. TCP/IP setup-press okay
5. Auto should show as “Off”
6. TCP/IP should show as “On”
7. DHCP/Boot should show as “Off”

If any of these are not listed on display correctly press ok, reset to either On or Off and then enter correct IP address.

Press okay button and follow steps on display menu to exit back to main menu display screen.

SOURCE: PDF documents do not print completely on my Xerox Phaser 8500

I am having the same problem. Sometimes my Xerox Phaser 8500 prints a PDF or web page fine, and other times I get pages and pages of what looks like PostScript code. I thought I had installed the most recent printer drivers, We are using primarily Macs with OS 10.4 or 10.5. One recent change is that we connected the printer to an Airport Express using a USB cable, which is sweet when it works correctly....any ideas???
