IMPORTANT SAFETY SYMBOLS AND PRECAUTIONS
What the icons and signs in this user’s guide mean:
These warning signs are here to prevent injury to you and others. Follow them explicitly. After reading this section, keep it in a safe
place for future reference.
WARNING
Hazards or unsafe practices that may result in severe personal injury or death.
CAUTION
Hazards or unsafe practices that may result in minor personal injury or property damage.
CAUTION
To reduce the risk of fire, explosion, electric shock, or personal injury when using your laser Multi-Function Printer (MFP),
follow these basic safety precautions:
Do NOT attempt.
Do NOT disassemble.
Do NOT touch.
Follow directions explicitly.
Unplug the power plug from the wall socket.
Ensure the MFP is grounded to prevent electric shock.
Call the service center for help.
1.Read and understand all instructions.
2.Use common sense whenever operating electrical appliances.
3.Follow all warnings and instructions marked on the printer and in the literature accompanying the printer.
4.If an operating instruction appears to conflict with safety information, heed the safety information. You may have misunderstood the
operating instruction. If you cannot resolve the conflict, contact your sales or service representative for assistance.
5.Unplug the printer from the AC wall socket and/or telephone jack before cleaning. Do not use liquid or aerosol cleaners. Use only a
damp cloth for cleaning.
6.Do not place the printer on an unstable cart, stand or table. It may fall, causing serious damage.
7.Your printer should never be placed on, near or over a radiator, heater, air conditioner or ventilation duct.
8.Do not allow anything to rest on the power. Do not place your printer where the cords will be abused by persons walking on them.
9.Do not overload wall outlets and extension cords. This can diminish performance, and may result in the risk of fire or electric shock.
10.Do not allow pets to chew on the AC power, telephone or computer interface cords.
11.Never push objects of any kind into the printer through case or cabinet openings. They may touch dangerous voltage points, creating
a risk of fire or shock. Never spill liquid of any kind onto or into the printer.
12.To reduce the risk of electric shock, do not disassemble the printer. Take it to a qualified service technician when repair work is
required. Opening or removing covers may expose you to dangerous voltages or other risks. Incorrect reassembly could cause
electric shock when the unit is subsequently used.
6 | Safety information
13.Unplug the printer from the telephone jack, computer and AC wall outlet and refer servicing to qualified service personnel under the
following conditions:
•When any part of the power cord, plug or connecting cable is damaged or frayed.
•If liquid has been spilled into the printer.
•If the printer has been exposed to rain or water.
•If the printer does not operate properly after instructions have been followed.
•If the printer has been dropped, or the cabinet appears damaged.
•If the printer exhibits a sudden and distinct change in performance.
14.Adjust only those controls covered by the operating instructions. Improper adjustment of other controls may result in damage, and
may require extensive work by a qualified service technician to restore the printer to normal operation.
15.Avoid using this printer during a lightning storm. There may be a remote risk of electric shock from lightning. If possible, unplug the
AC power and telephone cord for the duration of the lightning storm.
16.The Power cord supplied with your printer should be used for safe operation. If you are using a cord which is longer than 2 m with
110 V printer, then it should be 16 AWG
a
or bigger.
17.Use only No.26 AWG or larger telephone line cord.
18.SAVE THESE INSTRUCTIONS
19.This printer can be operated only in the country you have purchased (due to different voltage, telecommunication configuration and
etc.).

UNDERSTANDING THE STATUS LED
The color of the Status LED indicates the printer's current status.
ACKNOWLEDGING THE STATUS OF THE
TONER CARTRIDGE
The status of toner cartridges is indicated by the Status LED and the LCD
display. If the toner cartridge is low or needs to be replaced, the Status LED
turns red and the display shows the message. However the arrow mark
shows which color toner is of concern or needs replacement with a new
cartridge.
Example:
The above example shows the yellow cartridge status indicated by the
arrow. Check the message to find out what the problem is and how to solve
it. See "Understanding display messages"on page62 for more information
on error messages.
STATUSDESCRIPTION

This chapter gives you step-by-step instructions for setting up the printer.
This chapter includes:
•Setting up the hardware
•System requirements
•Setting up the network
•Printer's basic settings
SETTING UP THE HARDWARE
This section shows the steps to set up the hardware which is explained in
the Quick Install Guide. Ensure you read Quick Install Guide and complete
following steps.
1.Select a stable location.
Select a level, stable place with adequate space for air circulation. Allow
extra space to open covers and trays.
The area should be well-ventilated and away from direct sunlight or
sources of heat, cold, and humidity. Do not set the printer close to the
edge of your desk or table.
Printing is suitable for altitudes under 1,000 m (3,281 ft.). Refer to the
altitude setting to optimize your printing. See "Altitude adjustment"on
page20 for more information.
Select a flat, stable surface so that the printer is not inclined greater than
2 mm (0.08 inch). Otherwise, printing quality may be affected.
2.Unpack the printer and check all the enclosed items.
3.Remove the tape holding the printer tightly.
4.Load paper.
5.Ensure that all the cables are connected to the printer.
6.Turn the printer on.
When you move the printer, do not tilt or turn it upside down.
Otherwise, the inside of the printer may be contaminated by toner,
which can damage the printer or result in bad print quality.

SETTING UP THE NETWORK
You need to set up the network protocols on the printer to use it in the
network environment. You can set up the basic network settings through the
printer's control panel.
Supported operation environments
The following table shows the network environments supported by the
printer:
Configuring network protocol via the printer
To set up TCP/IP network parameters:
1.Ensure your printer is connected to the network with an RJ-45 Ethernet
cable.
2.Ensure you have turned on the printer.
3.Press Menu on the control panel, until you see Network on the bottom
line of the display and press OK.
4.Press the left/right arrow until TCP/IP appears and press OK.
5.Press the left/right arrow until Static appears and press OK.
6.Press the left/right arrow until IP Address appears and press OK.
Enter a byte between 0 and 255 using the number keypad and press the
left/right arrow to move between bytes.
Repeat this to complete the address from the 1st byte to the 4th byte.
7.When you have finished, press OK.
Repeat steps 6 and 7 to configure the other TCP/IP parameters: subnet
mask and gateway address.
Using the SetIP program
This program is for the network IP setting using the MAC address which is
the hardware serial number of the network printer card or interface.
Especially, it helps the network administrator set several network IPs at the
same time.
Installing the program
1.Insert the driver CD provided along with your machine. When the
driver CD runs automatically, close the window.
2.Start Windows Explorer and open the X drive. (X represents your
CDROM drive.)
3.Double-click Application > SetIP.
4.Double-click Setup.exe to install this program.
5.Click OK.
If necessary, select a language from the drop-down list.
6.Follow the instructions in the window and complete the installation.
Setting network values
1.Print the printer’s network configuration report to find your printer’s
MAC address. See "Printing reports"on page49.
2.From the Windows Start menu, select All Programs→Dell→Dell
printers→Dell 1235cn Color Laser MFP→SetIP.
3.Click to open the TCP/IP configuration window.
4.Enter the network card's MAC address, IP address, subnet mask,
default gateway, and then click Apply.
5.Click OK. The printer prints the network information. Confirm that the
settings are correct.
6.Click Exit.
Installing the driver software
You have to install the printer software for printing. The software includes
drivers, applications, and other user friendly programs. The following
procedure is based on Windows XP. If you use Macintosh operating system,
