Deskjet 6940 duplex

I have a 6940 deskjet connected to my LAN via ethernet with the optional a duplex unit to allow automatic duplex printing. All worked well until I upgraded to Windows 7 Ultimate and now the dulpex unit is no longer recognised.

Can't find Paper Saving Options > Automatic/Two-Sided Printing anywhere in Printer Properties, Printing Preferences or Properties rt-click menu. What am I missing???
There are a few possibilities: go to the Devices and Printers folder, right click on the Deskjet 6940, Printer Properties, Printing Shortcuts, then select Two Sided (Duplex) Printing, Apply. Alternately you could select the "Finishing" tab and select Print on Both Sides with Use auto duplex unit.

Connected Deskjet 6940 to computer with windows 7 64 bit, duplex print will not work?

I have a Deskjet 6940 model C8970A. The Duplex printer function does not work. It will manually ask me to turn around all the pages to print on the other side. Before it would print front then back of page at a time. I have Windows 7 64 bit on the new computer.

Hi,
The Duplex Unit is disabled by default, make sure to enable the accessory as following:
Enter Control Panel > Devices and Printers
Right click the HP Deskjet 6940 icon, then click Printer Properties.
Select the Device Settings tab.
Set the Duplex Unit as Installed, click OK.
Now set Print On Both Sides as Automatically from the Printing Preferences Dialog.
Please let me know if you may still experience any issue,

How to align deskjet 6940 in windows 7 using windows std drivers

I have a deskjet 6940 printer installed in Windows 7 64 bit using the standard Win 7 drivers and it works fine The issue is what about aligning the printer? If you get new cartridges, the first thing you do is align the printer. Win 7 drivers do not do this. When can we get something to be able to align the printer under Win 7?
Thanks,
Vic

AFAIK the Deskjet 6940 performs an automatic alignment when a new cartridge is installed. The printer will print an alignment page and scan it automatically while printing to complete the alignment process without any user intervention required.
I think you can also force an alignment as follows: turn on the printer, then press and hold the power button and while pressing the power button press the resume button (to the right of the X button) three times, then release the power button. (This works for the Deskjet 6550 and other models, I think it applies to the 6940 as well.)

Trying to network my hp deskjet 6940 printer via a new win 7 64 pc. the printer shows as "offline"

I am trying to network my hp deskjet 6940 printer via a new win 7 64 pc. The printer is visible but shows as "offline" and will not respond.
Can the hp deskjet 6940 printer operate over a lan using a win 7 64 pc?
Thanks!

Borneodiver,
Since the site says the driver is already in Windows 7, then a different method of adding the printer will need to be performed to get the driver from Windows Update.
First, uninstall the printer from the Windows 7 system.
1. go to devices and printers and select Add Printer at the top.
2. Select Add a local printer.
3. Create a new port with port type Local Port.
4. The port name will indicate where the printer is located. The format will be \\<computer name>\<printer share name>. Leave out the < > symbols. For me, this would be \\mycomputer\printer.
5. The next screen will show a list of various printers. Click the Windows Update button to update the list to the most current.
6. Select your model printer from the list.
The rest of the prompts should continue from there without any issue. I do not have a photosmart 7760 to get the rest of the prompts from there, but it should work after these steps are completed on the Windows 7 system.
If the printer was added using the network option, then it won't work on Windows 7 and there won't be an option for the driver since a network driver doesn't really exist for the printer since it is not natively networked.
Selecting the network option is usually selected in this process and it appears to not work with printers that are shared from a computer. This process tricks the Windows 7 system into running the printer as if it was actually connected to the printer, but the port name directs it to the host computer.
Let me know what happens.
I did find these steps here in jimbo45's post. I did perform the steps with a different computer and printer successfully, but it should work in this scenario as well.

Deskjet 6940 - multiple black cartridge 96 installation error messages

I have a new Deskjet 6940. I installed the black 96 cartridge. Printer keeps saying it is not installed correctly. I cleaned the cartridge, ran the jet/bubble test. Finally I replaced the cartridge, same installation error message. I do not get the error message for the color 97 cartridge. Is this problem common to the 6940? Not sure what my options are. Thanks

have the same problem. We installed cartiridge and did a test page by holding power and cancel buttons at same time. Nothing is showing up for the black cartridge. Maybe cleaning something would help, but I can't find any information on how to access the information using Vista.

Deskjet 6940 keeps going offline

I have a Deskjet 6940 connected directly to my router and both PC's run Vista. Often, the printer goes offline and the only solution that I have is to reinstall the printer. Any solutions?
Thanks

Just to be clear, you have a LAN cable connecting your Deskjet 6940 to your router, right?
When the printer goes "offline", can you access the printer's internal web page by browsing to its IP address? You can get the printer's IP address by pressing the check-mark button to print out the network status.
When the printer goes "offline", does power-cycling the printer help?
Finally, we can manually install the printer. This might work better. Here's the sequence for Vista:
Click >> Start >> Control panel >> Printer.
Click the 'Add Printer' icon. The 'Add Printer' dialog box opens.
Click 'Next' button on the 'Welcome to the Add Printer' Wizard dialog box.
Select 'Local printer' in the Local or Network Printer dialog box.
Under Select a Printer Port option, select "Create a new port" and select "Standard TCP/IP Port" and click "Next" button.
In the "Welcome to the Add Standard TCP/IP printer port wizard" make sure that the printer is turned on. Click "Next" button.
Under "Add Standard TCP/IP Printer Port" enter the printer's host name that is printed from the printer's netwotrk configuration page.
Now, select HP (not Hewlett-Packard) from the list of manufacturers, select Deskjet 6900 from the list of Printer models and click 'Next' button.
The Printer name will be highlighted on the next window. Click 'Next' button.
It will ask for the Printer name -- leave the default value.
Click 'Yes' for making the printer default. Click 'Next' button.
The Print Test Page box appears.
Select 'Yes' to print a test page.
Click 'Finish' button to complete the installation.
It should print a test page.

Deskjet 6940 connected via ethernet cable to Airport, will not print

Hello,
I used to run my HP Deskjet 6940 printer using a USB connection. I recently installed an Apple Airport Extreme so I can print wirelessly. As required, the printer is now connected to the Airport using an ethernet cable, and the green network light is on. On the advice of an HP rep via telephone, I uninstalled all older HP software and reinstalled HP software downloaded from the HP website.
When I try to add the printer on my "System Preferences," it opens a panel that contains the following options:
Protocol: Automatically chooses "line printer daemon--LPD"
Address: Blank but allows me type in the assigned IP address
Print using: No idea.
Two more things: when I open HP device manager, and select 'configure a networked printer, all network confirguation info appears fine but the manager does not allow me to "apply" it. Not sure if this is important but no printer utilities show up in my utlities folder since the new software download. Thanks.
This question was solved.

It looks like you are running a Mac.
First of all, the driver for the Deskjet 6940 is built into the Mac OS. You really didn't need to download extra stuff from www.hp.com (sorry about the bad advice).
Next, let's verify that the printer is on the network. From Safari, select Bookmarks, Show All Bookmarks. Select Bonjour from the left hand pane and verify that the Deskjet 6940 appears on the list of devices found on your network.
Next, follow these instructions to reset the Mac printing subsystem: http://support.apple.com/kb/HT1341
Now add the printer from the Print & Fax applet under System Preferences by pressing the [+] button. The Deskjet 6940 should be listed as one of the Bonjour kind of printers. Select it and then press Add.
I think that should do it.

My Deskjet 6940 is having problems pulling paper into the printer

Have had a HP Deskjet 6940 for about 2-4 years. Has worked great the entire time. Today in the middle of a print job, my printer freaked out and the ink cartridges inside moved quickly from side to side for a bit and now when I try to print, my printer sounds like the ink cartridges are moving into position and it sounds like the printer is going to work properly, but then I get an error that there is no paper in the printer.
Have tried resetting the printer, have turned it on and off many times, have even uninstalled the printer and reinstalled it. Have also cleaned the paper rollers in the back of the printer and made sure that there is not too much paper in the printer/the paper is in good condition (no tears, etc.).
Any suggestions on what to do next? Maybe it is time to get a new printer? Because I have had it for a couple of years, getting it serviced would probably cost as much as or more than the printer itself is worth.
Thanks!

Sounds like you have done some of the steps in this document, but have a look it might help.

HP Deskjet 6940 Printing problems

Hello,
I have recently purchased a HP Deskjet 6940 which I have owned for only 1 week. Problem is that when I try to print digital photos or just high definition pictures, even pictures from a digital camera, the printer seems to crap out on printing the photos. The quality is horrible the resolution is disturbing. Basically the printer doesnt print the pictures on par with what I expect it to. The lines are all over the paper the colors don't match, its weird. Normal pages I can print but when it comes to photos the printer just doesnt do the job. Any suggestions on what is wrong with my printer, for I do know something is definitely wrong with the printer because it does have the capability to print photos neatly and accurately. Thanks.

Deskjet 6940 causing a blue screen and rebooting PC on bootup

I have a strange problem with a clients PC. Whenever it boots up, if the Deskjet 6940 is connected via a usb cable it blue screens and reboots. The PC was recently updated to Service Pack 3, at first I thought the amount of memory was too low (248 mb, with 8 shared with video). So I upgraded the memory to 1 Gb but it still happens, if the printer is not plugged in it goes into Windows and works fine. if I then plug the printer in it reboots immediately.
I've tried different USB sockets, I've tried uninstalling the drivers and all the HP software, rebooting and downloading the latest drivers from HP. This seemed to cure it for a few hours, but later that same day the client called me again to say it had rebooted again.
I have spoken to HP support in the UK and was told that HP have issues with Service Pack 3 of XP. I found this hard to believe and also embarrassing - this is a new IT support contract and I recommended that all the PC's were upgraded to SP3.

I would suggest you upgrade teh drivers for your motherboard and also update the BIOS of your motherboard too and see if that resolves the issue.

Why is my Deskjet 6940 printing mirror image ?

The printout on my Deskjet 6940 is very clear and concise but it is in mirror image, you have to hold it up to the light and read it from the other side. What am I doing wrong? Maljal76
This question was solved.
View Solution.

What operating system? In Windows 7 there is a checkbox in the "Finishing" tab for "Mirror Image", make sure you uncheck this box. I would expect similar options in other drivers.

Deskjet 6940 offline to wireless Vista machine

Hi,
I have a network-attached HP Deskjet 6940. All the machines on the domain are running XP, either wired or wireless, except one, which is a wireless laptop running Vista. All the machines except the Vista machine can see & print to the printer. However, the Vista machine reports that the printer is offline and nothing will print to it. I ran the installation program to install the printer on the Vista machine some time ago, but I I cannot say if it ever worked or not.
Any suggestions as to how to enable this printer to be online to the Vista machine?
Thanks.
Dan

First, disable the security system on the Vista machine to see if it is interfering. Next, try to Add a Printer:
1. Make sure the printer is turned on and connected to your network. Verify that you can access the printer's internal web page by browsing to its IP address before continuing.
2. Click >> Start >> Control panel >> Printers.
3. Click the Add a printer
4. Select Local printer
5. Select Create a new port and select Standard TCP/IP Port and click Next button.
6. Under Device type, select TCP/IP Device. Under Hostname or IP address, enter the printer's host name (found on the printer's network configuration report the generated above). Click Next.
If you get a message about Additional Port Information Required, then the printer was not found using the host name. You can go back and retry or using the printer's IP address instead of the host name.
7. Select Hewlett-Packard from the list of manufacturers and select and select your printer model. Click Next.
If your printer model was not listed, then select Have Disk, browse the HP CD that came with your printer and select the first file that starts with hp and ends with inf. Click Open then OK. Select your printer model. Click Next.
8. If you are asked, use the currently installed driver.
9. It will ask for the Printer name -- enter a new name or use the existing one. This will be the name of the printer that you select from other applications.
10. You may be asked to share the printer. Make a choice and click Next.
11. The Print Test Page box appears. Go ahead and print it.
12. Click Finish.

Deskjet 6940 not printing PFD's

I have one of the above attached directly to the PC via USB cable, the PC is winXP Business SP3.
When I try to print out a PDF document the printer makes a noise, I can see the job Spooling(then this disapears very quickly) then nothing. After this attempt, when I get a print job out(not PDF) I get a blank page before the printed job.
All else is fine. Could it be a Postscript problem? I have the latest drivers installed, the properties ofthe PDF doc show me that it is avaliable to be printed, but just no job comes out.

Did you install through software update this week, the HP Printer Drivers v.2.11 for OS X? In the text file, /var/log/cups/error_log, is there any helpful information about failed prints?
Have your deleted your printer from preferences and reinstalled it? The 6940 series is still supported.
I would create an arbitrary folder name, let's call it HPprefs. With the Finder, navigate to your ~/Library/Preferences folder and look for the printer preferences that contain something like these ... yours may be different for the 6940.
com.apple.print.custompresets.forprinter.hplaser.plist
com.hp.print.psdriver.pde.plist
com.hp.printerutility.plist
Highlight them and from a right button, choose copy these files. Then within the HPprefs folder, hold down the option key and choose move items here.
Now remove your printer from Print & Fax preference pane and set it up again. Try printing from Word or Preview again.

Deskjet f2480 - duplex / 2-side printing

Hello there,
i have been trying to get this HP deskjet F2480 to print double sided but it always prints the odd pages but i cannot get it to print the even pages.
my previous hp had an onscreen and a button prompt for the reverse side printing. this one doesnt.
i have contacted the HP online technical team twice now. the first time the technician insisted that this model doesnt support duplex printing (despite the HP website saying that it does) and the second time i was told that it must be due to a corrupt software. i have therefore uninstalled it, reinstalled, installed all the available patches from HP website and this ....printer is still only printing odd pages! furthermore, the printer gets 'jammed' with the even pages still waiting in the queue to be printed. it is impossible to 'cancel' the printing at this stage and the only solution is to restart my laptop and disconnect from mains the printer....
has anyone had come accross the same issue? what is the solution?
or this printer just symply doesnt support duplex printing???
thank you for all possible advice.
Regina

Hi Badly%20Drawn%20Boy,
Please let me know what version of Adobe Reader are you using.
You might try printing any other PDF file with the same settings and check for the same.
Let me know.
