Bluetooth faxing broken in 10.4.8

I use my cellphone to fax things, via bluetooth. It's a great technology, which has been a lot of fun...but it has stopped working since upgrading to 10.4.8 on both my Powerbook G4 and my PowerMac G5.
The "classic" way to set this up:
* System Prefs -> Print and Fax
* Click "+" to add something; option-click "More printers..."
* Choose "Advanced," then Device: "Bluetooth-Modem", and Printer Model: "Other"
* Navigate to /System/Library/Frameworks/ApplicationServices.framework/Frameworks/PrintCore.f ramework/Resources/English.lproj/Fax.ppd
* Click OK a bunch, and it works.
...but now, it only faxes part of a page, then quits, and says that the fax is "on hold" in the Bluetooth-Modem application.
My cellphone is a Motorola e815, though that shouldn't matter because the same phone worked in 10.4.7 just fine...
Any help is most appreciated!
Powerbook G4, PowerMac G5, a few beige G3's   Mac OS X (10.4.8)  

To attempt to resolve this issue try the following suggestions...
1. Open Disk Utility, located in the Applications->Utilities folder. Select your boot volume and click "Verify Disk".
2. Using Disk Utility select your boot volume and click "Repair Permissions".
3. Download and apply the Combo update. This version of the 10.4.8 update is much larger than the one the Software Update application offers because it will update any version of OS X 10.4.x. It refreshes ALL files that have changed since the original version of 10.4. A good percentage of people find that applying the Combo update resolves problems. Of course make sure you download the Intel version for your Mac Book.
The above suggestions are pretty much standard troubleshooting procedures. Hopefully one will do the trick. If not the next step is to start looking for preference files that may have been corrupted during the update.
If you are an experienced troubleshooter and have already tried these tips I apologize.

  • Bluetooth Faxing for GSM Sony Ericsson 630 in Tiger

    Please look for the following in the Finder Help:Mac Help
    "bluetooth fax"
    Worked like a charm with the above phone model on my Powerbook 1.5Ghz with internal Bluetooth. Please note after following the instructions closely, the Fax driver is added, but does not appear until you send the fax, and the "Bluetooth-modem" is chosen in the "Set up Fax Modem"
    This solution does not require a GPRS connection, but will work like any phone call on your phone.
    Enjoy.

    As the info contains some screen pics, I cannot include it here. But the question arises, are you using 10.4 - Tiger? Did you choose finder and then go into the help menu there? I would like to stress that I only tried it with the phone that I mentioned above.
    I include the text part from the Help item below:
    "Faxing over Bluetooth is possible in Mac OS X 10.4 Tiger (and Mac OS X 10.3 Panther), but not all wireless carriers and phones support faxing—and this function is not supported by AppleCare.
    If you do want to add a Bluetooth-Modem fax device in Mac OS X 10.4 or later, you must add it manually. Note: Faxing must be supported by the phone and wireless carrier, too, for this to work. Follow these steps to add the device in Tiger:
    If you're using a Bluetooth adapter, connect it to your computer if it isn't.
    From the Apple menu, choose System Preferences.
    Click Print & Fax to display the preferences.
    Click the Printing tab.
    Click the plus sign button; the Printer Browser window opens.
    Option-click the More Printers button.
    In the sheet that appears, choose Advanced from the top pop-up menu. (If you don't see Advanced in the menu, click Cancel and repeat the previous step.)
    From the Device pop-up menu, choose Bluetooth-Modem. (If this doesn't appear, be sure that your Bluetooth adapter is connected.)
    From the Printer Model pop-up menu, choose Other.
    In the resulting "Choose a File" dialog, select your Mac OS X volume icon.

  • MacBook Pro, BlueTooth Fax Modem with Treo 700p EVDO

    MacOSX 10.4.6 w/ all of the latest Software Updates.
    I followed the steps below:
    1. In System Preferences, go to Print & Fax
    2. Open the Printer Browser (click "+" in the Printing tab)

    8. Finally, click Add
    Then to FAX...I did the following...
    Texedit.App
    File -> Print...
    and selected the PDF Fax Option.
    It acted like it was dialing the fax number (xxx-xxx-xxxx), the Treo 700p lit up like it was receiving the commands, but nothing happened. I couldn 't even get it to dial a normal PSTN number.
    Is there something else I need to do?

    Apparently there is a fee for using any Treo device as a modem through both Verizon and Sprint. While the easy connectivity of Bluetooth is attractive, most people are interested in attaching the Treo via USB for the data speed transfer factor. After heavy research to attempt to connect my iBook G4 to the internet via the Treo 700p without having to pay Verizon's $15 surcharge, I came across USB Modem. USB Modem supports connecting your Mac to the Internet using the Treo 600, 650 and 700p. And instead of paying $15 monthly, this application is only $25 and offers a free trial to make sure it is compatible with your phone and Mac. But FYI...you have to have the 700p to take advantage of the EVDO broadband network.

  • Apple Bluetooth keyboard broken (with technical sollution)

    Hello,
    I've got a bluetooth apple keyboard (the Dutch alu small version).
    Using rechargeable batteries I sometimes have to replace them.
    When I do replace the batt. the keyboard won't work, no green led comes up.
    also tried the caps-lock to check, but this also won't light-up.
    So, Thinking it was the batteries, tried some new ones, and they work.
    At this time I thought also the problems would be the batteries, but it wasn't.
    I've change the batteries a few times this year, and sometimes the keyboard worked, and sometime it didn't. Until a few days after warranty (23-dec-08) it stopt working.
    I've tried changing batteries over and over again.
    I've checked the voltage of the batteries, and they where fine.
    A store told me, no warranty, buy a new one.
    So first I wan't to know what the problem is, so I disassembled the keyboard and made a few pictures so you would also know how to.
    The problem is: The power of the batteries never reaches the circuit-board.
    I can disassemble a few things, but I can't get out the main-problem part.
    I think it's the springy thing in the batterie compartment, which does not give through the + voltage, the - was okay (checked with resistanse measuring).
    I've read a few problems with this keyboard..... What should I do next?
    The keyboard costed 80,- Euro's...
    I would like to change it for an usb version as I don't trust the bluetooth's anymore because of this (I found) mechanical error in design.

    An update about the broken keyboard.
    I called the Dutch Aple store helpdesk phone number. The person was very friendly, asked me about some products that I owned and tried to solve it via the normal procedures and asked for an exeption.
    But like normal procedures: The keyboard was 15 months young, so 3 month over warranty
    They did not took the exeption for a keyboard of 80,- euros.
    I told them I was happy with a cabled keyboard (half cheaper for apple, and because I don't trust the bluetooth inside wiring).
    It would cost apple almost nothing for a wired keyboard.
    In a few years I bought a mac-pro, and 2 macbooks, I thought they would help me out over a few euro's.
    Next step:
    The friendly person tried to call Customer Relations Ireland, but they were close at the moment I'll have to call back tomorrow.
    Backup step:
    Cut open the alu part which blocks my way of repairing the keyboard.
    Will take some time, but the fix will cost a few drops of soldering stuff.
    At least this approach boosts the trust in online shopping
    via the apple store I must say. Now, let's hope they can help me out.

  • HP Send Fax - Broken

    Problem occurs on LaserJet Pro 200 Color MFP M276nw.
    Print, Scan, ePrint, etc works fine. Fax works fine at the printer itself (manually feeding paper through).
    Fax does not work using the Windows application "HP Send Fax". The error dialog shows everytime, no matter how many times I uninstall/reinstall the entire software package from HP for the printer.
    Windows Fax and Scan and print to Fax does not work because this printer does not create its own Fax port.
    Downgrading to Internet Explorer 10 (as some discussion around sending fax via the PC suggests) is NOT AN OPTION due to corporate security policies.
    Help?

    Hi kcnet,
    I understand that you are unable to send a fax through the software. I can help you.
    Do you also have the Laserjet 200 M276 printer also?
    How Do I Find My Model Number or Product Number?
    Can you send a fax from the printer?
    I would disable all the start up programs and temporarily turn off the Antivirus Software to see if there is a program interfering in the back ground. How to use MSCONFIG . Click on the start up tab and click disable all.
    Try and send another fax again through the software.
    Then you will have to go back and enable the startup programs and turn the Antivirus Software back on again.
    Follow the steps in this document to get to the device manager to check for the printer entries. See if you have any conflicts for the fax driver. Also check devices and printers, to see if there is a icon for the fax.
     How do I get into Windows Device Manager?
    If the issue persists, just to rule out a network or communication issue, connect the printer directly to the computer by a USB cable to see if you have the same results. This way we will know if it is software related or a communication issue.
    If the issue persists, uninstall the printer software and then download and run the HP Printer Install Wizard for Windows. HP Printer Install Wizard for Windows.
    If you need further assistance, just let me know.
    Have a nice day!

  • Bluetooth streaming broken in update 10.3.1.x

    No more able to stream to bluetooth automotive device in latest 10.3.1.x
    Was working fine in 10.3.0.x
    Any clues ?

    Blame Verizon, why they took so long. My BlackBerry Z10 is STL100-4 too, don't know why this Z10 is actually aimed for Verizon is sold in Indonesia. I updated my Z10 yesterday using Sachesi. Now my BlackBerry Z10 is running OS 10.3.2.858. Next time I plan go back to Android.

  • Bluetooth suddenly broken?

    two days ago, my phone started doing this thing: when it automatically locked, it would stop connecting to my wireless and when I opened System Prefs, it wouldn't load and then System Prefs would crash. I was unable to turn the phone off (the lock button wouldn't work correctly) and only a hard restart would work. I restored factory settings via iTunes.
    Now, my Mac Air won't connect via bluetooth. It connects for a second and then the error message appears "The Bluetooth network is unavilalbe. There was an error connecting to your device. Make sure the device is turned on and in range." When I try to connect to the Mac Air from the iPhone's bluetooth menu it says "Connection Unsuccessful. Make sure "MacBook Air" is tuned on and in range." (But the iPhone is right next to the computer and i JUST browsed the device.)
    HELP!
    1. Bluetooth is on on my iPhone and it says "now discoverable"
    2. The device has been located by my computer and is listed in the bluetooth tab.
    3. I have installed the latest Mac Air updates (which showed up yesterday)
    Also, the iPhone is syncing very slowly. Its been off and on syncing for hours over the last two days and its still not complete (and its only syncing 40 G).
    Any advice at all is appreciated!

    A few questions before I give you some advice
    What model of headset do you have? Where and when did you get it? How long have you owned it?
    What happened to the ear hook exactly?
    Regardless, I'd recommend you call us directly for advice, since the process can vary by country: http://www.sonyericsson.com/cws/corporate/common/contact/phonelist They should be able to point you in the right direction!

  • Bluetooth Module Broken?

    just recently my logitech mouse has stopped working so i decided to save up and but a magic mouse. however before purchasing it i wanted to see if my mbp had bluetooth and was in working condition. however when ever i try to pair it up with any other bluetooth device i get a message saying "No Bluetooth Hardware Found" and when i go to About This Mac>More Info under Bluetooth it says No Information Found.
    What I've Tried
    - turning off the mbp on and off
    - removing the bottom cover and disconnected the battery
    - while on boot up press and hold the power button for a hard restart
    Should i do a complete restore? as in restore using the given Mac OSX cds? i tried restoring with time machine but no luck there.
    I was wondering if anyone else has had this problem and resolved it. I need my mouse for school work and the multi touch pad gets annoying to use for countless hours. Is there anything i am missing or trouble shooting incorrectly? If so please feel free to give advice or insight on this problem.
    But i know for sure i had bluetooth working before because i was able to sync my old blackberry before via bluetooth.
    thanks in advance and appreciate it

    I have an X61 working with Bluetooth here, but running Vista.
    If XP behaves the same way, you won't see anything in Device Manager until you switch on the Bluetooth using Fn-F5. 
    You don't mention installing Microsoft Bluetooth Support for Windows XP, which you do need.
    I don't work for Lenovo. I'm a crazy volunteer!

  • Bluetooth streaming broken by iOS4

    My 3G still pairs just fine with my bluetooth car stereo (Pioneer FH-P8000B) for phone calls, but for some reason, music no longer streams reliably... Once it worked to un-pair and re-pair it, but it doesn't always... Any suggestions? Much appreciated.

    There is no way you roll back to the previous level unless you jail-break.
    Does you head unit have a 'Play' button that you would use to play media output from the iphone??
    If you do, re-pair the phone and head unit and press play on the head unit.
    This worked for my headphones. Strange thing is once I press play on the my headphones the it woke up the phone and restored full control back to the phone.

  • Bluetooth now broken

    Hey guys, is your bluetooth not working anymore? Mine isn't anymore after the software update. Looks like Microsoft made a fix for the other bluetooth issues which I wasn't encountering. Now, I'm affected. LOL!

    Most update issues can be resolved by hard resetting if you are willing to try it. You can backup data and setting to the cloud. Apps can be reinstalled with an app called Reinstaller

  • 1.2 Bluetooth Update Broken... no more Bluetooth!

    I ran the 1.2 updater, not only does it fail to update, but it also nerfed my old firmware so now I have NO Bluetooth. Nothing under system preferences, and the icon on the menu bar says "Bluetooth: Not Available". Its like it never existed?!

    I'm having the same issues as everyone else with this Bluetooth Firmware Update 1.2 ...
    FWIW, after updating to 10.4.4 my System Profiler is listing:

    So the software version number has gone up, and the firmware number is well above 1.2 ... Is this Bluetooth Firmware Update 1.2 even needed (in my case)? It may just be a fluke that it's listing in the Software Update panel. I think we might be better off just ignoring it. It would be nice if Apple could definitively tell us more about when you'd need this update and when you wouldn't... For everyone who is having this update fail, is your firmware version number about 1.2 (is it 1.5xx)?

  • Iphone 6 with IOS 8.0.2 bluetooth broken with RHB430N Radio in 2011 Ram 1500

    I got my 64GB Iphone 6 just after release date, paired properly with my RHB430N radio in my 2011 Dodge Ram 1500 and worked great. When the new update of IOS came out 8.0.2, I installed that on my phone. Now the bluetooth is broken with my radio. It seems to pair ok from the radio side but I get a message that the phone cant see the uconnect radio during pairing. When I try and make a call, It wont work through voice activation, if I do get to work, the call stays active for about 5sec on the radio then it shuts off, the phone stays on making the call. Weird!
    I tried a factory reset on the radio, as well as network reset on my iphone with no luck. My Iphone 4S i had previously paired and worked fine with IOS 7.1.2
    anyone else with the issue? I noticed a few other people with different vehicle makes with the same issue after the 8.0.2 update and like I said it paired and worked fine with IOS 8.0 out of the box.
    any fixes or work arounds available meantime?

    I got my 6 three days ago (fine device, by the way. Meg St Clair will be proud of me: I finally took the plunge, I who claimed that I would never buy another iPhone, but I'm dithering...), and so far, no issues, none whatsoever, when syncing my phone via USB.
    WiFi syncing is another matter, though, because the phone simply doesn't appear in iTunes. I've checked all the right boxes, made sure the phone was set to accept WiFi syncing, to no avail.
    I'll look into it this weekend, just in case I missed something.
    But I can tell you this: all the content I had backed-up is now back on the phone, nothing's missing. I have a 2006 MacBook Pro running Snow Leppard.

  • Fax issue with HP OfficeJet 7210 All-in-one

    Hi everyone,
    I've got an issue with my HP OfficeJet 7210 All-in-one printer/fax (USB connection)
    I'm under Mac OS X 10.5 (Leopard).
    When I was under Tiger, my printer/fax worked properly.
    After the upgrade to Leopard, the printer/fax was still installed (HP 7210 was displayed as installed in the printer list of the System Preferences).
    The printer works fine but the fax doesn't ! An error consistenly occurs when I try to send a fax.
    Thus, I decided to uninstall every HP components from my Mac. Then I proceeded a fresh install of the CD software/driver I received with my printer/fax.
    During the installation, I get an error : "HP AIO TRAP has quit". I went further and continue the installation till the end by ignoring the problem.
    The printer is still working fine but I'm unable to install my fax in the System Preferences because the fax simply doesn't appear either on the "Fax" tab or on the "More printer" tab.
    Only an unuseful "Bluetooth" fax appear, I can install it but it's impossible to send a fax with it : http://users.cybernet.be/ptsalos/hp-leo1.png
    In the "More printer" tab I got this : http://users.cybernet.be/ptsalos/hp-leo2.png ... It seems that no fax are detected (no fax are displayed in "HP AiO Télécopie" and the "Add" button is gray).
    I hope you could help me !
    PS: the fax works properly under Bootcamp with Windows XP PRO SP2
    Thank you very much.

    OK, so enough software is available (or will so been available) for me to start posting these types of workarounds (and getting more of you up and running). And remember, what I am about to tell you is NOT supported by HP, so if you run into problems doing this do NOT call customer support. I am posting this stuff here to try to help out the community. I will stop posting if this gets abused (even once).
    If you have an HP OfficeJet 7310 or 7210 printer, go to HP.com/support, tell it you have a 7410, and download the installer (follow my instructions on the [Beta Announcement|http://discussions.apple.com/thread.jspa?threadID=1252889&tstart=0 ] thread if you need more details.
    Now follow these instructions:
    Step 1: Run the installer, and follow the onscreen prompts.
    Step 2: When the screen comes up to select your printer, check the box my printer isn't listed and continue.
    Step 3: On the next screen select the OfficeJet 7400 Series and continue.
    Step 4: Select the type of connectivity to your device.
    Step 5: Install the software (this may take several minutes).
    Step 6: When you get to the Setup Assistant, skip it. Make sure you de-select the two checkboxes before you continue otherwise it will remind you every time you log in.
    Step 7: Go into the Print & Fax System Preference and manually add your print queue.
    Step 8: Go into the Print & Fax System Preference and manually add your fax queue.
    Step 9: Start using your device.
    Congratulations, you now should have a fully functioning device under Leopard. So what won't work with this work around:
    1) The documentation on your device will be wrong.
    2) If you did not previously set up a station ID for the fax, one will not be set.
    3) Device Manager will not know anything about your device so the functionality there will be pretty useless (most stuff can be done through other means though). However if you already have a Tiger install, even this should (theoretically work).
    4) Good question, if you run into any other issues post them here, I may have forgotten something.
    WARNING! WARNING! WARNING!
    Please install the final drivers when they come out, and preferable the beta drivers too for your device too! Just because things are working for you does not mean that this configuration is supported (its not) or that there aren't any known problems (there may be, we certainly don't test it) so please take caution and update when possible.
    Just trying to help.

  • Hp Office Jet Pro 8600 A910, suddenly can't send fax. Reveiving faxes are ok.

    We can't send any fax, but we can still receive a fax. This happened suddenly without any changes (on device or our telephone line) When sending a fax it dials and gives a busy tone. After that we get a error sheet pointing out Error 388, communication error. Following things we did:- Tried sending fax on our other phone line to rule out broken phone cable/connections.- Called to phone and from phone to fax which worked.- Printed out T90 testsheet. All tests passed.- Tried faxing with ECM off or in other words turned off the error connection mode.- Tried faxing with lower connection speed setting.- Checked other settings to see if there was anything wrong, but all okay.- Powered off, disconnected power cable for at least 15 seconds. Is the fax broken or anything else we can try?

    Hi , I see you have been troubleshooting an issue with your Officejet Pro 8600 no longer able to send faxes, and I think I may have found some more information for you. Can you specify your your exact printer model for me? In your post title you say it is an 'Office Jet Pro 8600 A910' but and A910 is an Officejet 8500A. How Do I Find My Model Number or Product Number? Seems like an odd question, but the printer make a copy? It could be an issue with the scanner mechanism.
     Is the printer connected directly to a wall outlet or is it in a surge protector or a power bar? We want to connect it to a wall outlet just so we can eliminate the power source as the root cause. See this document for more information about Issues when Connected to an Uninterruptible Power Supply/Power Strip/Surge Protector (Note: This document is not limited to Laserjet printers.)
     HP regularly releases firmware updates that may also correct the problem you are experiencing. You can click on this link to;Get Printer Updates for HP Officejet Pro 8600 (N911), Officejet 6600 (H711) and Officejet 6700 Premium (H711) e-All-in-One Printer SeriesGet Printer Updates for HP Officejet 6500A, and Officejet Pro 8500A e-All-in-One Printer Series Have you tried to run the Fax Test Report? It's usually located in the setup menu, under tools. The fax test report will let you know if it finds any problems and how to correct them. Once everything passes on the fax test report, you can Test Your HP Fax Machine with the HP Fax Test Service.  I reviewed the error code you provided from the Interpreting Error Codes in Fax Communication Error or Fax History Reports document.  Error 388: There is too much noise on the line for a valid connection between two fax machines to complete. The noise problem might go away over time. Retry the fax reception when telephone line conditions have improved. Call the telephone provider if line conditions fail to improve. Have you touched base with the phone company to make sure they have not changed anything on their end? Does this same error occur with every number you try to dial?  You could see if anything in Fax Sending Fails Intermittently or Fails for Only One Recipient is helpful as well.  Please let me know if these steps resolved your issue, or if there is anything else I can do to help.  I look forward to hearing from you!   Thanks,
