HP 7410 Troubles

Using 10.6.2 and a networked hp 7410 all-in-one. I have downloaded the SL drivers from hp and am unable to get printing working. With the hp installer, it is unable to find the printer. I think this is a SL problem and here is why, all the other pc's (with the other OS) print to it fine. The last thing i remember doing is downloading the SL HP driver update. Do you have to install the hp driver update from apple update when using the hp drivers/software? Anybody else seen this problem?

I have an OJ7410 connected wirelessly to my iMac using 10.6.2. I ignored the HP drivers and only used the drivers provided by Apple here.
If you have already downloaded those then go to System Preferences, Printer & Fax, highlight the 7410 on the left and click - to remove it. The next step would be to download the drivers noted above and follow any installation instructions. Then go to System Preferences, Printer & Fax and click the + sign to add your 7410 and it should work assuming you don't have any other issues.
Regards,
Roger

Switched to Mac - Trouble installing HP Officejet 7410

I'm switching from Windows to Mac after a disaster while upgrading to Vista (another story). Mac mini is up and running fine. I've been very pleased with my HP Officejet 7410 since late 2004. However, installation with the Mac has been a challenge.
Using the original Mac disc provided with the 7410 at purchase, install runs ok - but when connected via USB, the 7410 is never recognized. When connected via wireless, the "fax" version installs (don't know if it works), but the printer version does not install automatically. When I manually add the printer, I get to the point of selecting the driver, but the 7410 is not included and I have to selected another printer with Gutenprint driver. Prints ok, but no scan / copy.
Checking via Mac support (http://support.apple.com/kb/HT1370), the 7410 is listed as one of the printers included in the Mac OS X 10.5.2 software pack, using an HP 4.0.1 driver - but it is not listed in the "select" printer options on my machine.
I've downloaded the latest Mac driver pack from HP, and run through that process, but still with the same results.
Any idea where I can get just the driver and where I need to "park it" on my Mac hard drive so that is is recognized as an available driver that I can select?

Greg - Well I tried the "reset" suggestion after running the new, downloaded driver from HP - and same results. When I go to add the new printer, the system does not automatically find the correct driver. I'm offered "Select a driver" and the HP 7410 does not show up in the list - and mainly Gutenprint drivers are listed - no HP drivers.
My HP Photosmart 475 printer installs just fine.
It still seems to be how to get the HP driver in my "available" list.

HP 7410 and XP Pro not compatible

I have an Officejet 7410 in my home network with 4 other computers using a Belkin router and access point.
I am having no trouble printing to the 7410 from Windows 7 or the Vista machines (go figure HP is ahead of the curve!). I can't for the life of me get the 7410 to work with my 2 XP Pro SP 3 boxes.
I can see the printer and the port it is using (192.168.2.3 std TCP/IP port) and that is what the other boxes are connecting to. However everytime I tell XP to connect through that port it asks me to pick a HP model from a list. Of course with the lack of communication between HP and Microsoft; windows XP has never heard of the OfficeJet 7410.
OK, I suppose I should download the driver from the HP site. That is ez to do. After download, I run the exe file and it seems to install but where and what???? Fead 2.5 operates and than a 2 slider screen operates and than voila all disappears and still it is not installed.
My 7410 is slowly dying because of the use I put through it and I will be darned if I will buy another HP product, particularly the 8500 which is simply not working for folks.

Mini-Dvi-to-Video trouble

I just bought a mini-dvi-to-video adapter so I could use my TV as a display. More specifically, so I could use my VCR to record what's on my Mac's display. I also bought a headphone-to-composite cable adapter. I'm using a double-headed (is that one male or female? It's male, isn't it?) composite cable from the video adapter to the VCR. The problem is, it doesn't show up. The sound plays (and records) fine, but the video neither shows up on the TV screen nor records onto the tape. What's the problem? Both adapters are Dynex, my computer's a Late 2006 iMac (I think), the cable is WireLogic, and both the VCR and TV are Sony. Please help, thanks.

So if you eliminate the double headed splitter and plug straight into the TV, does the video still not show up?
FYI, there have been reports in the past of trouble with the Dynex video adapter. You may need to purchase the Apple OEM one. The Dynex may lack having a ROM inside of it with a proper EDID in the ROM. This is crucial to the Mac.

Trouble Using Apple's Video Adapter

I am having trouble getting my eMac to work with the Apple Mini-DVI to Video Adapter. There are no directions telling you how to use it or to even get it to work. I want to use it to import videos from my Sony Hi8 camcorder and was told by Apple's Live help that this is what I needed to import video and make DVDs. How do I get this adapter to work?

Welcome aboard.
I think the adapter you have is for video output, not input. To input video to the eMac you need a firewire connection. Sony cameras typically have a 4 wire connector which is smaller than the 6 wire plug on the mac, so you need a cable that has a 4 wire connector on one end and a 6 wire connector on the other. Cameras often (but not always) come with such a cable. You also need a digital camcorder- not just Hi8., although Sony does make cameras that will do both. If you camera does not have digital output, you need a convertor box.

Hi, I am having trouble MacBook Air crashing since Yosemite upgrade. I ran an Etresoft check but I don't know what it means... my system runs slowly and crashes. I have to force shutdown. Sometimes screen is black for a split second b/w webmail pages

Hello,
I am having trouble with my MacBook Air 13 inch June 2012 MacBook Air5, 2 4GB RAM details below in Etresoft report. I recently upgraded to Yosemite and am having system trouble. My computer crashes and I have to force quit to restart. When using webmail there is a black screen for a split second between pages. This did not happen before. I am worried that it is not running properly and perhaps I need to revert to the previous operating system. I only have a MacBook Air and no need to share images between a tablet or phone so I did not need the new photo sharing software of Yosemite. I wonder if I don't have enough RAM to run it? I did not run time machine before I made the upgrade as I did not realise the significance of an upgrade as not very Mac literate. Any advice on whether my system is in danger... most appreciated! I am writing a book and making a back up but this machine is my lifeline and my work is conducted through it. It ran perfectly before... the Yosemite upgrade has perhaps highlighted some problems and it has unnerved me!
Thanks ever so much for your advice!

I had a 1 TB Drive that was connected as a back up, but it is no longer recognized by the mac. How may I trouble shoot to reconnect?

how do I trouble shoot this?

Good News.
If this is your only Backup would suggest getting a New EHD and creating another one... Preferably a Clone if you don't already have one.

I am having trouble printing to an Epson XP600. It is a new printer and it has been replaced because we thought it was the printer. Basically, when I print from Excel, only color will print.

What 24 character verification is it talking about???? I've never had so much trouble just to download something that is going to take a day and half

I purchased the student version of Photoshop and Lightroom a few weeks ago
I have a 19 digit code that i had to scratch to get, a 30 digit number under the bar code, and a 6 digit authorization code that seems to be completely pointless. I started off putting in the 19 digit code with all my other information, but it wanted 24. so I filled in the rest with zeros. Then it starts giving me so much trouble I don't think I'll ever attempt to get photoshop again.

Trouble accessing photos.

Hello! Need help! Having trouble accessing photos from Adobe Photoshop Album Starter Edition 3.0, I had a free trial but never registered the program because I was not using it. The other day I was taking pics off a Canon camera, & they automatically loaded into that site. I selected cancel several times, but the program did not respond. Once they completely loaded in, the program asked if I wanted to erase photos from the camera, I selected no but it started erasing them, I was able to stop it but 44 were erased off the camera. I can see the photos in the program but can not access them since I never registered. I tried to register now but received email saying that program has expired. So how do I get my photos? Please help! The photos are not mine, I was loading them from a friends camera, & they are important vacation memories to her! Thanks! Ruth

Launch iPhoto with the Command+Option keys held down and rebuild the library.
Since only one option can be run at a time start with Option #1, followed by #3 and then #4.
Fix #2
Using iPhoto Library Manager to Rebuild Your iPhoto Library
Download iPhoto Library Manager and launch.
Click on the Add Library button, navigate to your Home/Pictures folder and select your iPhoto Library folder.
Now that the library is listed in the left hand pane of iPLM, click on your library and go to the File ➙ Rebuild Library menu option
In the next window name the new library and select the location you want it to be placed.
Click on the Create button.
Note: This creates a new library based on the LIbraryData.xml file in the library and will recover Events, Albums, keywords, titles and comments but not books, calendars or slideshows. The original library will be left untouched for further attempts at fixing the problem or in case the rebuilt library is not satisfactory.

Trouble Opening Illustrator and Photoshop CS2??

When opening Adobe Illustrator CS2 I receive a Windows Box showing Adobe Illustrator: Illustrator.exe - Application Error The instruction at "0x003c197d" referenced memory at "0x000000000". The memory could not be "read". Click on OK to terminate the program.
I am also having trouble accessing Adobe Photoshop CS2. When I open the program it simply stays in one sequence as a loop and does not completely open.

32 bit Windows XP
I also tried uninstalling and re-installing the full program and it still has the same problem.
I even checked my ram by moving a single memory card from one slot to the next to see if that was the problem but still the same error messages.

Searching on the web, most results I found lead to this page, where it is said that the problem is due to badly tuned overcurrent protection, and advocated that unplugging and switching off the computer for a little while gets things back into normal. This does not really work for me; the problem seems to occur more randomly, unfortunately with high probability (my camera is available after less than one boot out of ten).
I tried to ensure that the ehci-hcd module is loaded at boot with the ignore-oc option (with a file in /etc/module-load.d/), to no avail.
I also wrote a script which alternatively removes and reloads the ehci-pci driver until my device is found in lsusb. It is sometimes helpful, but usually not. And even when my device is found that way, it can only be used for a while before disappearing again.
Anyway, such a hack is unacceptable... So, my questions are:
is it indeed related to overcurrent protection ?
is there anything else I can try ?
should I file somewhere an other of the numerous bug reports about "unable to enumerate USB device" already existing ?
If of any importance, I am running linux 3.15.7, because at the time I installed my system, I couldn't get the hybrid graphic card Intel/AMD working under 3.16.

Hello Sue,
I have an iPad 3, iPad Mini and iPhone 5S and they are all sluggish on capitalisation using shift keys. I hope that Apple will solve the problem because it is driving me crazy.
I find using a Microsoft Surface and Windows 8 phone, which I also have, work as well as all the ios devices before the ios 7 upgrade.
It has something to do with the length of time that you need to hold the shift key down. The shift key needs to be held longer than the letter key for the capitalisation to work. For some reason, this is a major change in the way we have learnt to touch type on computers. I am having to relearn how to type!
