|6||Print Cartridge Status lights|
For a description of the following buttons and lights, click the appropriate option:
Power button and light
Use the Power button to turn the printer on and off. It can take a few seconds for the printer to turn on after you press the Power button.
The Power light flashes when the printer is processing.
Caution Always use the Power button to turn the printer on and off. Using a power strip, surge protector, or a wall-mounted switch to turn the printer on and off might cause printer failure.
The printer is designed with an auto -off feature that, when set, automatically places the printer into a low power mode when it has been idle for 30 minutes. In this mode, the printer continues to consume a maximum 3.0 watts of power and turns back on automatically when print jobs are sent to the printer. You can manually turn the printer off by pressing and holding the Power button for three seconds. When the printer is manually turned off, the printer uses less than one watt of power.

Four print cartridges can be used with the printer.
- Black print cartridge
- Tri-color print cartridge
- Photo print cartridge
- Gray photo print cartridge
Note The availability of print cartridges varies by country/region.
Use print cartridges
The print cartridges can be used in the following ways:
- Everyday printing: Use the black and tri-color print cartridges for everyday print jobs.
- Quality color photos: For more vibrant colors when printing color photographs or other special documents, remove the black print cartridge and install a photo print cartridge. The photo print cartridge, in combination with the tri-color print cartridge, provides you with virtually grain-free photos.
- Quality black-and-white photos: For outstanding black-and-white photographs, remove the black print cartridge and use a gray photo print cartridge in combination with the tri-color print cartridge.
Replace print cartridges
When buying print cartridges, look for the print cartridge selection number.
User’s guide 15
You can find the selection number in three places:
- Selection number label: Look at the label on the print cartridge that you are replacing.
- Selection number label
- Printer documentation: For a list of print cartridge selection numbers, see the reference guide that came with the printer.
- Print Cartridge Ordering Information dialog box: For a list of print cartridge selection numbers, open the printer Toolbox, click the Estimated Ink Level tab, and then click the Print Cartridge Information button.
If a print cartridge runs out of ink, the printer can operate in ink-backup mode.
Use the ink-backup mode to operate the printer with only one print cartridge. The ink-backup mode is initiated when a print cartridge is removed from the print cartridge cradle.
Ink-backup mode output
Printing in ink-backup mode slows the printer and affects the quality of printouts.
Note HP does not recommend using the photo print cartridge or the gray photo print cartridge for ink-backup mode.
16 HP Deskjet 6940 series
Exit ink-backup mode
Install two print cartridges in the printer to exit ink-backup mode.
For instructions about installing a print cartridge, see the print cartridge installation page.
Automatic paper-type sensor
The HP automatic paper-type sensor detects the paper in the printer, and then selects optimal print settings for that media. The result is fewer mouse clicks to start printing, and automatic optimal print quality on plain, photo, brochure and other high-quality papers. The sensor also checks the paper width to ensure it matches the size selected in the printer software. If the widths are different, the printer warns you so that you do not waste a sheet of paper.
When the auto paper-type sensor is engaged, the printer uses a red optical sensor light to scan the first page of a document and determine the best paper-type setting and check paper width. If the paper width is different from the printer software, the printer warns you and gives you the opportunity to stop printing. If the width matches, the printer determines the paper-type setting and the page is printed.
Note The Automatic Paper-Type Sensor is not available for documents that are printed from the 250-Sheet Plain Paper Tray Accessory or the Auto Two-Sided Print Accessory with Small Paper Tray.
Caution Do not place the printer in direct sunlight. Direct sunlight can interfere with the auto paper-type sensor.
Use the Quiet mode feature when you require quieter printing, such as when a baby is sleeping nearby, or when clients are in the office. To activate Quiet mode, open the Printer Properties dialog box, click the Paper/Quality tab, and then click Quiet Printing. By activating Quiet mode, the speed and sound level of the print job is reduced. To resume normal printing speed, click Quiet Printing again to clear this feature.
Quiet mode can be used in Normal, Fast Normal, and Draft print modes.

4 Connect to the printer
The printer connects to the computer with a universal serial bus (USB) cable. The computer must be running Windows 98 SE or later to use a USB cable.
For instructions about connecting the printer with a USB cable, see the setup poster that came with the printer.
Note A USB cable might not be packaged with the printer.
To change a USB connection to an Ethernet connection
If you initially installed the printer as a standalone printer with a USB connection, and later decided to set up the printer on a network, you must change how the printer is accessed. If you already understand how to connect to a network, you can use the general instructions that follow. For more detailed instructions on connecting the printer to a network, see the setup poster.
- Unplug the USB connection from the back of the printer.
- Connect an Ethernet cable from the Ethernet port on the back of the printer to an available Ethernet port on the router, switch, or access point.
- Insert the printer software CD in the computer CD-ROM drive. The Setup Wizard begins.
- On the Connection Type screen, select Wired Network, and then click Next.
- Follow the onscreen instructions to complete the network installation.
- When the installation is complete, open Printers and Faxes in Control Panel and delete the printers for the USB installation.

Wired Ethernet networking

For a description of the printer’s Ethernet feature, click one of the following options:
To install the printer on an Ethernet network, follow the Ethernet installation instructions.
Hubs, switches, and routers
Hubs, switches, and routers can look similar, but there are important differences:
- Hubs are passive. Other devices on the network plug into the hub in order to communicate with one another. A hub does not manage the network.
- A switch allows devices on a network to communicate directly with one another in a smooth and efficient manner. A switch monitors and directs network traffic in order to allow each transmission the most possible bandwidth. By monitoring network traffic, a switch minimizes collisions and maximizes speed.
- Routers primarily connect different networks (for example, connecting a home network to the Internet). Routers are active. Routers have network administration tools, such as firewalls and DHCP. A router can act as a gateway, while a hub and a switch cannot.
Use a CAT-5 Ethernet cable to connect the printer to an Ethernet network. Ethernet cables have an RJ-45 plug.
User’s guide 19
1 RJ-45 plug
Networks might not be connected to the Internet.
Ethernet network examples
To see some examples of Ethernet networks, see the Ethernet network examples page.
Computers on the network send print jobs directly to the printer, which prints them in the order received.
The printer can accept print jobs sent simultaneously from four users.
For example, if five users each send a print job to the printer at the same time, the printer accepts four of the print jobs and rejects the fifth. The user who sent the fifth print job should wait a few minutes and then resend the print job.
What you need for a wired network
To connect the printer to a wired network, you need the following:
- A functional Ethernet network that includes an Ethernet router, switch, or a wireless access point with Ethernet ports
- CAT-5 Ethernet cable
Although standard Ethernet cables look similar to standard telephone cables, they are not interchangeable. There is a different number of wires in each one and each
