HP Photosmart 7520 WiFi interference with a Laptop

Hi,
I have a problem with my HP Photosmart 7520
I had a problem with internet connection on my laptop. For some reason, internet worked well on any other device (we have 2 Iphones, 2 macbooks, 2 ipads, and One HP printer) but it didn't work on my computer. Therefore, I decided to buy a new "Advanced WiFI" router from Rogers, that has two chanels 2.4Ghz and 5.0 Ghz. However, it didn't solve the problem, but it revialed the roots of it.
I noticed that when the printer is on, the connection on my computer is very slow. Moreover, once we've changed the router, the printer stoped printing through wifi from any deviece. I did Wireless set up about 20 times, but every time I try to print something, it shows "The printer is off". I've found on your forum this article: http://h30434.www3.hp.com/t5/Printer-Networking-and-Wireless/HP-Printer-interfering-with-signal-from...
I did everything the same, but it didn't help.
It cannot be a problem with a network or router, because it was checked plenty of time and it works well with other devices. Speaking about my computer, it works excellent in any other network, and all the tests showed positive results.
Please tell me the way I can fix that problem. My laptop is Macbook Air OS X 10.9.5

HP 7510 Photosmart - Lost WiFi Connectivity with Windows 7 laptop

Have had the 7510 for over a year and have configured/used it with the same Toshiba Windows 7 Home Premium 64-bit laptop which is our home PC. Two days ago, tried to print over the WLAN and an error message said the 7510 was offline. Power cycled/reset, et...nothing. I have a work PC (also Windows 7) that can wireless access the 7510 without issue.
So, I uninstalled and reinstalled the 7510 drivers. During the set-up, states that the printer IP is on a different network than the computer. This is not true...both are connected the same SSID. I can even access the EWS using the printer IP (192.168.1.3) that I got from the Network Configuration Printout. This printout validates the network status, network SSID, IP, etc are all good.
I did an IP release/renew on the Toshiba, no change.
I did tether the printer to the computer via USB to at least complete the driver install. When I tried the HP Utility to 'convert the printer from USB to wireless, I get the message stating the Printer and Computer are not on the same router. However, have verifed that they are on the same router.
What else can I try? This appears to be an IP conflict with my home Toshiba laptop. If my work PC has no issues with accessing the 7510 and I can get to the EWS from both PCs, so I wouldn't think the Netgear WGR614 router is the issue.
Help!

Hi teeroy33,
I can't help but wonder if there is a firewall on the Toshiba that is blocking the communication. Let's use the HP Print and Scan Doctor. The following are some common problems that the Print and Scan Doctor can resolve easily:
' Printer is Offline ' or print jobs stuck in the print queue
Missing or corrupt drivers
Connectivity issues
Firewall issues
Please click here to open the link, download and run the HP Print and Scan Doctor.
Let me know the out come so that I can continue to work with you.

WiFi Card with Tungsten EH

I just received a PalmOne WiFi card for my Tungsten E2 for Fathers Day and was trying to set it up. I have been very unsuccessful. I have internet capabilities at home and at the office on my PC. I have WiFi capabilities with my laptop at work which allows me to take it anywhere in the building and stay connect to our network and all our application. I do not have a media network plan for my cell phone, but it is capable, I just don't subscribe. Do I need to add the data plan from my service provider (AT&T Wireless) in order for my WiFi card to work/connect to the internet or can it connect to free WiFi networks on it's own?
Post relates to: Palm Pilot

A cell plan has nothing to do with the Wifi card...
Have you viewed the help file at the top of the BlueTooth and Wifi section of the forum? It explains the basic settings needed to connect. I wrote it for the TX, but it's applicable to the Wifi card too.
Do you know the passwords and encryption settings at work? Have you tried entering them into the Wifi card's settings? Are they broadcasting in /b or mixed mode?
What isn't working at home? Do you have your all your router's settings entered correctly into the E2?

Photosmart 7520 on wireless network no longer recognized by laptop

The printer was fully functional on my wireless network, accessible by phone, tablet & laptop. Now it is not recognized by the laptop but still usable by other devices through the wireless network. The laptop is Windows 7 professional. The laptop and printer are both on the same (only) wireless network. I uninstalled the printer and driver from the laptop, temporarily disabled Norton Antivirus, then tried to install a new driver but installation failed. I repeated the entire process again, with the same results. What else should I try?

Hi @SaMi4,
Welcome to the HP Forums!
I noticed that your HP Photosmart 7520 that is on a wireless network, is no longer recognized by your laptop. I am sorry to hear about this, but I am happy to help!
I would recommend this printing guide, 'Printer is offline' Message Displays on the Computer and the Printer Does Not Print: Windows 7.
You would also benefit from this guide, Printer Does Not Maintain Wireless Connection. As this will help you maintain the connection.
Hope this helps, and have a wonderful day!

Can't connect to our wifi with my laptop, but pc and iphone can!

All devices (my boyfriends pc and my iphone and ipad) can log into our new wifi network except for my macbook pro. I can connect to any other wifi like the starbucks or our neighbors network, and all different hotel networks. I've never had a problem connecting with this laptop and have had it for years. Apple says it's comcasts, comcast says it's apple. I've spent hours on the phone with both and neither has solved the problem. HELP please anyone. I feel so constrained with this ethernet cord! And I don't want to get a new laptop just to get wifi.
I've reset the modem, I've changed login and password info, I've been on the phone with apple clearing out all my network history etc...
Thanks in advance to anyone who can offer some help.

Look at iOS Troubleshooting Wi-Fi networks and connections http://support.apple.com/kb/TS1398
Additional things to try.
Turn Off your iPad. Then turn Off (disconnect power cord) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
Change the channel on your wireless router. Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html

Slow scanning with photosmart 7520

I am scanning a bunch of old photos for a collage. Often you hear the scanner quickly scan the photo. Then it gets hung up for a long time showing a partial of the photo and a box that says "scanning" and a green progress bar. Sometimes it hangs up for 1 - 2 minutes. Some pictures only a few seconds. They are all about the same size photos. I am scanning on 200 dpi. Why does it take so much longer on most of the photos?

Hello @rmayes,
Welcome to the HP Support Forums!
I understand that you're experiencing a slow scanning issue when scanning from your HP Photosmart 7520 e-All-in-One Printer to your Windows 7 computer. I would like to assist you today with resolving this issue. Thank you for including that you are scanning your photos on 200 dpi. Rather than a printer, driver, or software issue I do believe that we're dealing with a connectivity issue or a firewall issue. When you print only 1-way communication is used. The computer sends the print command to the printer and the printer will then print the job. However, when you scan 2-way communication is required as the computer and printer send the scanned data back and forth until the full image is on the computer for you to work with. Because of this slow scanning issue I believe that something is interfering with the 2-way communication.
In order to provide you with accurate support I will need to clarify how your HP Photosmart is connected to your computer (USB, Wireless)?
In the meantime, I am going to have you run an MSConfig on your computer. This will allow us to temporarily disable all the background programs from running on your computer. Once the background programs are temporarily disabled I will have you test scanning again to verify if the speeds are faster. If the speed is faster with the background programs disabled than that will tell us that there is definitely a program on your computer causing this issue. Please follow the steps below.
Click on your Start menu
In the 'search programs and files' box right above Start, type msconfig and hit enter on your keyboard
When the System Configuration Window opens select 'Selective Startup' and uncheck Load Startup Items
Click the Services tab. Check the box at the bottom for Hide All Microsoft Services
Select Disable All
Select Apply and OK
Restart your computer when prompted
Once your computer comes back on please test scanning again.
Please respond to this post with the result of running the MSConfig. Should the issue persist be sure to let me know how your printer is connected to your computer. I look forward to hearing from you!

Streaky printing with new XL black cartridge (Photosmart 7520)

I installed a new HP XL black cartridge in the Photosmart 7520 about 10 days ago. Today the black and white text printing I mostly do started becoming unreadable - streaky, smudged, faint - even though the ink level report shows about 3/4 full for black (of course the report itself printed with streaks, etc.) I removed and re-inserted the black cartridge to make sure it was seated properly (it was and it is) and then I ran the clean cartridges function on the printer. The print quality report came back looking good (including alignment) except that the black area was streaky. After getting this print quality report, I tried printing text again. The first one page document printed somewhat streaky and with erratic faint areas; the second time I printed it, it was almost unreadable. Any suggestions?
This question was solved.

Repeated cleanings and then using the "align printer" function seemed to do the trick.

Photosmart 7520 error. there is a problem with the printer. turn printer off then on.

I have a photosmart 7520 experiencing the following issues.
Problem #1: Randomly all the lights start to blink off and on and the display reads the following :
Error . There is a problem with the printer. Turn printer off then on.
I cannot find any one action that triggers this to happen.
Problem #2: When the printer is turned on and idle, also at RANDOM times, the printer will "Ding" followed by the wireless light blinking. Then what sounds like the cartridges being cleaned, then a sound like the feeder spinning or the print head running full track from side to side, then ending with a "Ding" and then returning to normal.
When this occurs, the wireless connection is disconnected then reconnected. Also this Disables the "Scan to computer" function to all the computers on the network and requires manually re-enabling all .
From what I can tell the printer is restarting itself.
It is plugged directly into the wall outlet, no surge protector.
Tech support has already run me through the clean the print head steps, escalated me up the chain, and ultimately replaced the printer with a brand new one.
THE NEW PRINTER IS DOING ALL THE SAME THINGS AS THE PREVIOUS ONE.
This printer is connected wirelessly to a Netgear N900 router. My computers all running Windows 7, all are on the same network and workgroup and all are running Mcafee Total Protection.
If anyone is or has experienced the same or similar problems, I could sure use some help.
This question was solved.

How did you fix this?
I replaced an HP printer recently for a new Photosmart 7520 after a complete ink container emptied into the printer.
The old printer sometimes had difficulties switching it on and the new printer has the same problem.
Also the wireless connection regulary drops and can only be reenabled by switching of the printer and switching it back on, only this sometimes takes more than ten minutes before a simple push on the power button is translated in a power on of the printer.
Since the previous printer also suffered from these "power" issues, I think the problems are power related, but I have to check this first before I can say anything more about this.

Photosmart 7520 prints with green tint on all photos

Need help in finding cause and correcting printing problem that causes all photosto have a green cast to them.It is actually most notable on in darker or shadow areas of the photo.It almost has a sepia appearance to it in those areas only. Cartiages are new, alignment is good.I use Google Picasa for storage and printing, the problem also occurs with Canon DigitalPhoto Professional software from my Canon Ti4 camera.

Hello gclyde991, Welcome to the HP Forums. I see that you are having some issues with the print quality of your print outs. I do have a few steps that we can attempt to troubleshoot this issue. First off, please make sure that you have the printer power cable connected directly to a wall outlet and not a power bar/strip. Here is a document that uses a LaserJet printer as an example but it is meant for HP products in general. Please click on the following link that explains the Issues when Connected to an Uninterruptible Power Supply/Power Strip/Surge Protector. I have also located a document that deals with Fixing Print Quality Problems for the HP Photosmart 7520 e-All-in-One Printer Series. If you are still having issues, or if you have any other questions, please feel free to write me back. Cheers,

You should check with your Carrier before doing this as many charge very high fees for this use without a plan, and it's pretty expensive even with a plan.

Keep the preseleted LPT port amd click on Next.
Select HP from the Manufacturer pane and then select the HP Deskjet 6940 Series from the Printers list.

Finish the Wizard and confirm the changes.
Right click teh newly added 6940 and select Printer Porperties, open the ports tab and select the port with the otiginal printer model listed within the Printer column (e.g. HP Photosmart 7520), then click on OK.

New imac 27(Intel based,bought 2013) slow wifi connection with my Verizon fios actiontec router. All other wireless devices in the house(ipad 3gen,MacBook Air ,hp laptop) have a much faster connection. Should I change router settings to G only,etc

New imac 27(Intel based,bought 2013) slow wifi connection with my Verizon fios actiontec router. All other wireless devices in the house(ipad 3gen,MacBook Air ,hp laptop) have a much faster connection. Should I change router settings to G only,switch channel from auto to maybe 6,channel width to 20mhz? Already changed security settings to WPA2. Currently router is running in mixed b and g mode.

If you have one computer running on G they will all run on G. All ROUTERS are backward compatible, in otherwords if you have a group of computers and all of them are N compatible and one or two are G They will all work but the N computers will run at N and those that are G will run at G speed not N.
It can get confusing but really it is simple. The newest is 802.11 AC and ic used with the newest Mac Computers made available in November 2013. So if you have the newest Airport Extreme that is 802.11ac and the newest computers that are AC compliant your speed will be 5 times faster than anything on the market right now.

How to print on photo paper with HP Photosmart 7520 on iphoto '11

Dear All,
I have a very serious problem. I've tried so many settings and configurations without success.
Very simple. I cannot choose the photo tray in any way and I cannot print on photo paper.
I get everything on A4 format.
The printer is working fine wih other software (e.g. HP studio).
I can't believe I'm the only one.
Please help!
tks ;-)

Hi,
I came across such issues using AirPrint from Mac OS.. probably an Airprint bug.
Go to Print & Scan and click the plus sign.
From the extended add a printer dialog select the Photosmart 7520.
Open the Use drop-down and select the HP Photosmart 7520 from teh list (Instead the default AirPrint option)
Additionally from the iPhoto print dialog click Print, the OS print dialog will appear.
Set the Paper Source as Photo Tray under the Paper Type/Quality menu.

Color scanning problem with Photosmart 7520

I can not get my new Photosmart 7520 to scan in color.
The device scans to PDF, sending the file directly to my Mac computer but when I open the file the document is in b/w.
Everything else about the process works fine.
What should I do to capture color?
This question was solved.

Hi Magnusho,
Im suspecting that the default mode for the PDF is Grayscale/Black and White. To verify this, follow steps below:
1. Double click /Applications/Hewlett-Packard/HP Utility
2. Click "Scan to computer"
3. Click "Edit Scan Task..." button
4. Hp Scan wil launch and will open Preferences window
5. Select "Document (PDF)" or shortcuts that contains PDF
6. Click "Edit" button.
7. Click "Show Details" button. Scan Presets will display.
8.Check the Mode?
If the mode is in "Grayscale/Black and White" then thats the reason why the scan output is not color. If you want colored scan output, change the mode to Color. Then click "OK" button.
Try scanning again.
If this does not help you, please update me.
