Room Lights Dim or Flicker When Printer Starts
The following characteristics define this type of problem:

begins printing.
• The lights remain normal when the printer is not on.
• The printer generates printed sheets without a problem.
• The control panel does not display an error code.
The following procedure guides you through multiple actions that may solve this print image qual-
ity problem. Proceed one step at a time until the problem is solved—you may not need to complete
the entire procedure. If one of the steps in this procedure corrects the problem but the identical
problem returns in less than 50 prints, call for service.
1. Unplug all devices that are plugged into the same AC wall outlet as the printer.
During warm-up and at the start of each print run, the printer normally draws a large
amount of current. If other devices are running off of the same AC circuit, the accumulative
current draw may result in nearby lights momentarily dimming.
2. Have an electrician check your building wiring.
There may be a problem with the AC outlet or the AC wiring in the building that needs the
attention of a licensed electrician.

Printer Interferes with Nearby Radio or Television Reception
The following characteristics define this type of problem:
• When the printer begins printing, it causes audio noise in nearby radios or interferes with the
picture in nearby televisions.
• The printer generates printed sheets without a problem.
• The control panel does not display an error code.
The following procedure guides you through multiple actions that may solve this print image qual-
ity problem. Proceed one step at a time until the problem is solved—you may not need to complete
the entire procedure. If one of the steps in this procedure corrects the problem but the identical
problem returns in less than 50 prints, call for service.
1. If the radio/television is plugged into the same AC wall outlet as the printer, plug either the
printer or the radio/television into another AC outlet.
Electrical noise may be transmitted through the AC line. You can reduce the noise to the
radio/television by using a dedicated AC wall outlet for the printer.
2. Move the radio/television away from the printer.
