Use of Power Strips (RPT), Surge Devices (RTP+), and Uninterruptible Power Supplies (UPS) with Lexmark Laser Printers and Multifunction Products

Important Safety Information

	CAUTION -POTENTIAL INJURY: Do not use this product with extension cords, multi-outlet power strips, multi-outlet extenders, or UPS devices. The power capacity of these types of accessories can be easily overloaded by a laser printer and may result in a risk of fire, property damage, or poor printer performance.
	CAUTION -POTENTIAL INJURY: Only a Lexmark Inline Surge Protector that is properly connected between the printer and the power cord provided with the printer may be used with this product. The use of non-Lexmark surge protection devices may result in a risk of fire, property damage, or poor printer performance.

Use of power-regulating devices

Lexmark products are designed for use at the following voltage ranges:

Nominal Voltage / Range	Voltage / Range (Minimum / Maximum)
100V ac	90V-106V ac
110V-127V ac	99V-135V ac
220V-240V ac	198V-254V ac

The Lexmark product warranty may not
cover damages caused by power surges or operation of the printer outside of the voltage ranges indicated above. If you are using one of the devices noted above and the printer is not
functioning properly, you should turn the printer OFF
and unplug the power cord from the in-line device; then reconnect the power cord directly to an appropriately rated and properly grounded electrical outlet operating within the voltage tolerances noted above. If the printer functions properly while connected directly to the wall receptacle, then discontinue the use of the in-line device with the printer. Should the Lexmark product still not work properly, please consult the operating manual for troubleshooting instructions or contact a Lexmark authorized service representative. In reference to UPS devices, there are several matters of concern:

Most commonly available UPS devices do not
have the peak current capability to support the inrush current typical of a laser printer.

Incorrect application of a power regulating device may result in unpredictable error messages displayed on the operator panel.

The output of most UPS devices may not
allow for effective control of some switching elements critical to printer operations and, therefore, may generate a service condition.

If you still choose to use some type of non-Lexmark, external power-regulating device, Lexmark recommends that you install an appropriately rated device intended for the application. An appropriate device of choice is defined as one that is suitably rated for the printerrsquotescapeds power requirements and certified by UL
( Underwriterrsquotescapeds Laboratories
), another Nationally Recognized Testing Laboratory
, or a recognized safety certification body in the country/region of use. The specifications for the printer and the power regulating device should be carefully reviewed prior to using such a device because not
all device/printer combinations will function properly. The use of such devices is solely at your own discretion, and is not
covered under the Lexmark product warranty.
