Officejet L7680 spontaneously "disconnects". New USB, no help. Uninstalled, reinstalled, etc

My Officejet L7680 will start to print, then after 1/2 page, the solution center pops up with "disconnected" message. I purchased new USB, changed port, reinstalled, etc. Followed all instructions from HP. Still no help.

well it looks like I have a working solution ... I downloaded a freeware file called process.exe . I made a cmd file via notepad with the following contents:
rem this is to keep the HP network printer communicating with the desktops
rem
process -k "hpnetworkcommunicator.exe"
rem
process -k "scantopcactivationapp.exe"
rem
"C:\Program Files\HP\HP Officejet Pro 8600\Bin\HPNetworkcommunicator.exe"
rem
Start "" "C:\Program Files\HP\HP Officejet Pro 8600\Bin\ScanToPCActivationApp.exe" -deviceID CNXXXX:NW -scfn "HP Officejet Pro 8600 (Network)"
the XXXX is your printer serial number with an extra character or two. Pull that number from the port tab after you pull up "properties" for the 8600 printer.
This cmd file basically restarts the printer link. It opens a command window that launches the program to re-establish the link.. then it closes the command window. The launched program shows that the communication link is dead (just for a few seconds), but then it makes the connection... THEN you hit the close button and coninue your work until it dies again.
I may have it autorun every X hours if I can narrow down a good time. Until then I have a shortcut on the desktop to "FIX HP LINK" ... I only had to do this for my XP machines, as the vista one seemed OK.
What ticks me off is that I shouldn't have to do all of this diagnosis. It would be nice if there is a fix in the pipeline so the link stays stable al the time. I've spent hours trying to figure this crap out.
Anyhow, I hope the time I spent helps someone. PS, thanks to the OJ6500 thread that had the info for the scantopcactivationapp.exe program.
PS ... I'm still waiting for an engineer to contact me, if any HP employees are reading this.
PSS I haven't tried this without killing and restarting the hpnetworkcommunicator stuff, but it works for now.

Officejet L7680, corrupt PDF file when scanning

When scanning on my L7680, I have just started to have issues with a "General Error" message (on and off) and also a corrupt PDF file error. What can I do to fix this?
HELP!!!!

Hi 1193,
Welcome to the HP Forums!
I see that you cannot scan with your HP Officejet L7680, and I am happy to help you with this scanning issue!
For further assistance, I will need to know the following:
If you are using a Windows or Mac Operating System, and the version number. To find the exact version, visit this link. Whatsmyos.
If the printer is connected, Wireless, Ethernet, or USB.
If the power cable is plugged into a surge protector, or directly to the wall outlet. Issues when Connected to an Uninterruptible Power Supply/Power Strip/Surge Protector. This applies to Inkjet printers as well.
If the printer is able to make copies by itself.
If you are using Windows, please try our HP Print and Scan Doctor, and let me know what happens!
Hope to hear from you, and have a great day!

L7680 Can't connect via Network works fine direct connected via USB Please Help!

Greetings All,
I have an HP L7680 that has been having this same problem since I purchased it and the only cure that has ever worked is to completley reload Windows XP and start over which I am very tired of reloading XP to resolve a printer problem.
This has been posted by several other people but I don't see where anyone has posted a fix.
When I first install the printer everything usualy works fine and it runs fine for a few mionths. Then the first indicatrion of a problem is the scanner quits working. Then when I try to reinstall the software the printer does not show up. I read and tried every solution and have spent nuerous hours with HP support to no avail.
The printer works fine direct connected via a USB cable and it works fine with two other computers on the same network. One of the other computers has the exact same OS and is the same HP model laptop.
I don't think the uninstall is completley removing all the files or reinstalling everything fresh when I reload. I have tried the Level 1 through 4 uninstall utility posted on HP's site and have tried all sugestions posted in this forum.
Below is a better rundown of the problem.
When the Scan function is called, a "Scanning" window appears, and hangs
I have an HP Laptop with XP32 Bit software
Once the scanning window appears it stays there forever
Only way to clear scanning page is to terminate hpoews01.exe with Task Manager
Scanner does not show up in Paint or Photoshop ect.
Web Scan Does work and printer shows up using IP address.
Scanner shows up fine on a web page
HP support in India has been no help and now my printer is out of warranty so even less help
Thank you,
Dave

I had a similar problem with my OfficeJet L7680 and here's how I fixed it.
18APR10 - from Dan
     I lost my L7680 network link (using CAT5 from printer to router) and could not print to it over the network. However, I could print from a PC with a USB cable directly to the printer, but there are currently three PCs connected wireless to the network.  I think I have a viable solution for anyone with the same problem and is not related to the operating system of the PCs.
     Originally, I went to the HP site and downloaded the program for the L7680, Critical Update to Enhance Reliability of Network and USB Connectivity and Improve System Responsive.... This worked wonders until my modem and/or router went down. I could see ink levels from my PC, scan, print, and so on. Then I somehow lost my network connection again. When I checked the network settings on the L7680 printer panel (Setup, 5 - Network, 1 - View Network Settings, 2 - Display Wired Settings), I noticed a different IP address than the original 192.168.1.100. Once I figured out how to reset the printer to that one, it connected and worked as it should.
    Here's how to reset it: 1. Power down all devices (wired and wireless) to the router (I even disconnected the printer power cord and CAT5 cable at the printer); 2. Power down the modem and router - wait a minute or so before powering back up; 3. Power up the modem and give it a minute or so to go through system checks, which will normally acquire a new IP address from your ISP; 4. Power up the router and let it go through its system checks; 5. Connect the CAT5 cable from the printer to the router and power it up before you power up and connect any other computers. This should assign the printer the first IP address from the router, which should be 192.168.1.100. Once the printer goes through its start-up checks, you can check its assigned IP address from its panel. 6. Power up any other PCs or devices to the router. They should be assigned successive IP address numbers from the router. You can check these using a browser in the PC after typing in 192.168.1.1, logging in to the router, and checking the appropriate place in the router driver/software displayed in the browser. I was not able to reassign IP addresses in my router's driver/software to individual devices, but this method did the trick. I did not try to change the IP address of the printer from its panel to match what had been inadvertently reassigned to it. That might be another option to synchronize the printer and router with the same IP address. If the printer loses its connection again, you'll have to synchronize what the printer has with what the router shows. This worked for me.

New iPod not loading on computer w/ new USB card... HELP!

My new 30g 5g is only about a month old. I've been hooking it up to my computer (PC) via the old USB (1) and it has worked fine. I just got a new external drive which pushed me into needing more USB slots so I got a new USB 2.0 card (Startech) and put that in my computer. The drive and everything else works fine through the card, however, my ipod won't work properly with it. The iPod used to load on My Computer as an ipod with its name and when opened would show the folders on the iPod. Now, it loads as a "removable disk" with nothing inside. And it won't load in iTunes at all.
If I connect it through the old USB slot it seems to work as normal. Also, anything else I connect with the new USB card works fine.
I've tried updating iTunes, restarting, tried all the different ports on the new card, took the card out and reinstalled...
I've avoided wiping my iPod so far, but I know that is one option. My iPod is basically brand new so I'm stumped. Any help is appreciated.
PC Windows XP

my only suggestion would be to format it thru windows (mycomputer, right click the ipod, format, quick format) then restore it with the ipod updater.
i myself am looking into getting a usb 2.0 card because im hoping it will fix my problem with random disconnections. i hope you work it out.

first: why did you download the iOS Beta 8? If you are a developer, go to the Apple Developers website and check what they can do for your case.
second: setup an appointment to a Genius Bar for service.

Hi Johnfromglenver,
There are no Mac drivers for the HP Officejet K60 printer. Therefore it is not compatible with the Mac operating systems. Please call our technical support at 800-474-6836.

Firewire shared drives spontaneously disconnects - Please help!

Very odd problem that for whatever reason just started happening. I have 15 external FireWire 800 drives that half are shared on the network using AFP, the others are backup drives that run on Retrospect for the shared drives. This setup has run without any problems for a few years, then recently I'm having issues that all the drives (or a random few) will spontaneously disconnect, and will display an error on the server screen saying something to the effect that devices were ejected improperly, etc....
I'll look on the server Finder and some of the drives are gone. The only way to get them back is to power them off, and turn them back on. Sometimes AFP won't reshare the drives that were kicked off, and I'll have to restart AFP to share the drives again.
What is going on? I haven't done any updates, I'm running Server 10.5.8. Is it possible one of the drives may have a corrupted file on it that's causing some or all the drives to get kicked off? This is really frustrating as I'm having users knocked off the shared drives while working.
Any fix would be appreciated. Thanks.

Shut Down, unplug the AC cord from the Mac, and leave it unplugged for at least 15 minutes. Also power down the camcorder and unplug it from the G5.
Then plug the AC cord back in, boot the G5. Then plug the camcorder in and power it up.
Does System Profiler recognize the camcorder now?

OfficeJet L7680 runs dry after 5 pages at a time

Hi, I have an OfficeJet Pro L7680 that, up until a couple weeks ago worked pretty well. The main symptom is that it starts fading on the printing, basically ink seems to run out on all colors but magenta. The cartridges were half full, but about a year or so old when this started happening, so I replaced all the cartridges with absolutely no change in behavior. Now on a second set of all-new print cartridges for all colors, there's no change.
I've repeatedly run the clean printhead feature once or twice per day to try to clear this up, but the printer starts fading after about page 4 and won't print fully again for about 10 minutes of sitting idle -- at which point it'll print 1, maybe 2 pages and run out. If left to sit overnight, then I can print 4 or 5 pages again before running out of ink.
No errors are being reported on the printer or via printer software.
The cartridges are all new and genuine HP and show nearly 100% full status.
Nothing has changed on computer or network -- happens from all computers as well as the test pages printed from printer.
I know my way around printers having professionally maintained and cleaned them over last 30 years as a computer consulting expert, but this one has me stumped and its my own printer to boot, not one of my customers.
Any help appreciated -- not afraid to take printer apart to examine specific parts if anyone can tell me what's the most likely culprit here!
Thanks,
Michael

Hi Michael (mwlang),
I understand you have an Officejet L7680 that is not always printing properly and doesn't seem to respond to the printhead cleaning. I will certainly do my best to assist you with this.
I believe your culprit in this scenario is either the printheads, or the ink lines that go from the cartridges to the printheads. The ink lines on this unit are essentially hidden so I don't really have any tips on how to check them, but as you are a tech person, you may be able to figure that one out better than I could
As for the printheads, I will suggest you manually clean your printheads and then once that is done, run the printhead cleaning on the unit again and hopefully all should be well again!
Hope this helps, have a great day!

Officejet L7680 won't complete a scan. Windows 8.1

I have Dell desktop with Windows 8.1. I recently had to install a new hard drive and reinstall all my software. Prior to that I had Windows 8.0 and my Officejet L7680 printed and scanned just fine. After the new hard drive, it will not complete a scan and the HP scan app gets hung up. I upgraded to 8.1 and installed the proper drivers from HP for Windows 8.1. I've uninstalled and reinstalled the drivers a number of times. I've also used the HP Scrubber to remove all the software twice using Uninstall_L4.bat. No luck. Also tried HP Print & Scan Doctor and even it gets hung up. I'm about to just dump the printer and go get a new one. Since I've owned this printer I've always had issues with the software.

Hi kennyb777,
Welcome back to the Forums, I see it's been a couple of months since you last posted.
I understand that you are getting an error message when trying to scan with you Officejet L7680. I have included a document with detailed trouble shooting steps to take. You may have done some of the steps already, but it is important to perform the steps in the order they are presented.

New USB Power Adapter includes cable

I just got caught and hope this advice helps others...
The original USB iPod power adapter did NOT include a USB-to-dock cable. I just ordered the NEW USB power adapter and the extra cable. Guess what - it now includes the cable!

Did you find a solution Raf SR?
I have a similar problem. After initial (updating/restoring) issues with my ipod mini which I won't bore you with, I got it working and charging successfully through my PC via the USB cable. Then I bought a USB power adapter for when I am away from my PC. When I connected my ipod to the power adapter it did the brief "do not disconnect" thing then "OK to disconnect" with no attempt to charge. I left it overnight and the following morning it had the battery/triangle/exclamation mark symbol and I had to reset the ipod to get it to work (I did this while still connected to the power adapter).
I borrowed a friend's firewire power adapter and that worked fine. I went back to the store and swapped my usb power adapter for another (firewire power adapter wasn't available) and it did the same as the first one. The ipod still charges fine via the PC and usb cable.
I don't get it! Can anyone help? Thanks

TS2756 How can i create a new usb connection (service) on my iMac for sharing internet from my iPhone5 ( i seem have to deleted it )

How can i create a new usb connection (service) on my iMac for sharing internet from my iPhone5 ( i seem have to deleted it )
i know its not a problem whit my carrier o data plan or sharing preferences on the ipone because when i use it un my laptop it works perfectly through
the usb and even works on the Imac through wifi and bluethood tethering but NOT through usb!!.
the problem is that trying to make it work i deleted the "profile" usb iphone on the network prefereces panel. Now i only have 3 options: ethernet / wifi / bluetooth
but not the usb iPhone i used to have.
And when i try to add a new one i dont get a USB option.
can some one help me please??
this is how it looks (after the bluetooth PAN i used to have USB iPhone option)

The question would be more appropriate in the Mac forums as it is not really related to the iPhone.

Does anyone have any new recommendations to help iTunes recognize that my 128 iPhone and 128 iPad aren't 16 GB models?

I have suffered from this problem for years, but since upgrading to 128 iOS devices in September, the mysterious iTunes/iOS hidden data disease has gotten intolerable. Here's the deal:
I use my iPhone and iPad mostly for media consumption. I don't have a ton of apps. I have lots of videos, music through iTunes Match, and a few pictures. I'm one of those dinosaurs who doesn't use the cloud but downloads it, stores it, and syncs it via USB frequently (which I would bet is the root of my problem). Although I have a large capacity devices, I sync almost daily. And each time I sync, my displayed free space and the space iTunes allows me to use differs more and more. Old fixes used to involve such things as restoring the devices, turning off automatic syncing, turning off photo syncing, turning off other syncing apps, etc. And these things were temporary fixes.
Let me give you an example of what I mean by temporary. It has been exactly eight days since I last restored my iPad to brand spanking new, retaining nothing. In those eight days and approximately eight or nine manual USB syncs, each with an average of 60 GB transferred, I mysteriously have managed to lose 40 GB. This afternoon during my most recent sync, iTunes showed 86.3 GB free. However, as usual, it wouldn't sync anything close to that. By the time I had whittled my selections down to an acceptable amount, it still showed I had 47.2 GB free both in iTunes and in Settings on the iPad. Yet when tested it by trying to sync a 50 MB app, it said there was not enough available space. In days past, problems like this would take weeks or maybe even months to accumulate. And the culprit would usually be the "Other" category. When that happened, the remedies I described would help. This new beast is something else, though. Like I said, this took only eight days.
I finally decided to post something, though, after I reset my iPhone to factory settings this evening. When I was syncing the initial apps and videos, it would not let me sync more than 30 GB of material. I don't know what to do, guys. I bought the maximum capacity devices because I like my HD content. Does anyone know what I'm doing wrong? If you say I just need to sync less, (1), Apple needs to get its act together, and (2) It might sound crazy, but I can probably only push it to 2 days, so I'd only be postponing my problems a few days.
If anyone can help, I would appreciate it. Forgive me if this has been addressed elsewhere. I have spent time searching, but all I found was the answers I have already tried numerous times.

I got my baby iPhone the day it came out. Seriously, I love it. I'm not really mad about the price drop, a little frusterated, but I knew what I was getting myself into when I purchased mine so early. But, now that I know there are ringtones in the future, I just can't wait.
So basically, does anyone know for sure when we will be able to get the ringtones? And what about iTunes on the iPhone, when will that pop up? I'm sure these questions have been posted already, but I just can't seem to find a sure answer.
I'm worried that it is just my iPhone/computer that can't find the update to get all the cool new feautres, any help?

See

- I would start with
Removing and Reinstalling iTunes, QuickTime, and other software components for Windows XP
or
Removing and reinstalling iTunes and other software components for Windows Vista, Windows 7, or Windows 8
However, after your remove the Apple software components also remove the iCloud Control Panel via Windows Programs and Features app in the Window Control Panel. Then reinstall all the Apple software components
- Then do the other actions of:

Why is my new USB Superdrive not working?

When I connect my new USB superdrive (external disc drive) to my iMac, it doesn't show on my list of devices in Finder or on the desktop. I took it back to the store and it works on the store's iMacs. My eReader and USB memory stick both work.
Is there something I have to set in Preferences or software I have to load?

What year is your Mac? Is this the one you got?
http://store.apple.com/us/product/MD564ZM/A/apple-usb-superdrive#overview-4
It only works with the new 2012 iMacs (which would explain why it works with the Macs in the store) and a couple of other models.
You could try an SMC reset:
http://support.apple.com/kb/HT3964
and reset the PRAM:
http://support.apple.com/kb/PH11243
If that does not help and yours is a late 2012, then I have no answer for you except that unless someone else chimes in with one, I'd call Apple if you're still covered by the warranty or go back to the store.
Additionally, my LaCie external burner does not show on the desktop unless I have a disk inserted.
