Hi, I run a small computer lab (13 mac computers) at a university. I have a Phaser 7760 and am having trouble with it printing streaks on color printouts from Photoshop, Preview, and Safari. However, when I print from Illustrator all is fine. Any suggestions on what the problem might be? I know Illustrator has a different print menu, but am not sure what makes it so different. Thanks.
Try updating your firmware to the latest code level. You can find this on under the Support and Drivers tab on xerox.com. There wan an improvement to a data compression algorithm that will likely fix this issue you are seeing.
