5-26 Phaser 6300/6350/6360 Color Laser Printer Service Manual
Print-Quality Troubleshooting
Residual Image, Ghosting or Hot Offset
There are faint, ghostly images appearing on the page. The images may be
either from a previous page or from the page currently printed. The printer
displays no error code. This type of artifact can be related to the percent
coverage called out in the file being printed.
Hot Offset: A light image of the print is repeated and offset 82 mm. See
“Repeating Defects” on page 5-4.
Initial Actions:
■ Verify the correct media type is set at the Control Panel
■ Make sure the customer is using color correction (limiting color to max
240%). Other graphic applications can exceed 240%.
Note
For Phaser 6350 and 6360 configurations printing color at 36 ppm
and above limits color coverage to a maximum of 200%.
■ Try printing with fresh media from a recently opened ream.
