HP Laserjet M1132 MFP on Mac OS 10.7 - No Scanner Detected [ Edited ]

[trezi]

I just installed the HP Laserjet M1132 MFP on my mac mini (mid 2011) with OS X 10.7 (Lion).

I have the printer working fine with the right driver comming from the installation disk.

I have also upgraded the firmware to the latest one available for download from there site.

One thing happen during the installation was that I couldn't finish the installation properly at the time of applying custom settings, the wizard prompted me "You must have administrative right ....", which I have, and when mac OS needs it, he asks for it anyway. The only choice was to cancel, but drivers were installed.

Then, I launched HP Scan to check the scanner, and I have ... "No scanners availables" !!

I also run apple software update, but nothing!

Any help would be very much appreciated.

Regards,

Trezi!

Solved this problem! 

Sorry if there are errors of grammar, I am Brazilian, do not write in English, just read. So I'm using the google translator. 

I bought my HP LaserJet M1132 MFP after you have installed the Lion, and came across the same problem. When you install the driver in Lion, at the end of installation it said that my User had no administrative privileges to perform this action. And the printer still worked, but not the scanner. Qo user happens that I was installing was the manager. Then I had an idea, kind of a kludge, but the important thing that worked !!!!! 
  
  
I managed to solve this issue by enabling the super-user root and installing the drives by the super user root. 
  
As should be aware, the Mac OS is a Unix, and has all the features of a Unix system, even q many are hidden. 
  
In Unix-based systems (like Linux and the Lion) is a super user who has full and unrestricted access system settings.But what happens in Mac OS root user is disabled for "protection." 
  
So what I did was to enable the root user, log in by it, and install the drive, so the user would have no problems manageable to install the drive. 
  
When you finish the installation, it did not show the error message described above (as I imagined), and the scanner functioned normally for the program "HP Director". 
  
I do not know as it was in SnowLeopard, because as I said I bought my printer after you have already installed the Lion, but in the case of Lion the "Image Capture" to see the MAC did not work the scanner, even the "Readiris "that came with the printer. 
  
But the point I'm getting now typically scan the "HP Director" which comes on the CD for printer installation. It scans nicely and gives me the option to save the e-mail jpg or. For me to use the "Readiris" I scan the "HP Director", save  in jpg, open the program to run and put the opening jpg. (But to be honest I do not really use the "Readiris" just did it to test0
  
As the root user is disabled by default, you should follow the tutorial below to activate the super user. 
  
Once activated, do logof, and when you're on the login screen click "Other User". Then type "root" in the space reserved for user (without the quotes) and then type the password you set.

So you'll have logged in as root, then just install the printer driver as usual. 

Steps to enable root user in Lyon:

1. From the Apple menu choose System Preferences....
2. From the View menu choose Users & Groups.
3. Click the lock and authenticate as an administrator account.
4. Click Login Options....
5. Click the "Edit..." or "Join..." button at the bottom right.
6. Click the "Open Directory Utility..." button.
7. Click the lock in the Directory Utility window.
8. Enter an administrator account name and password, then click OK.
9. Choose Enable Root User from the Edit menu.
10. Enter the root password you wish to use in both the Password and Verify fields, then click OK

I hope I have helped!

A tools call launch as root is needed after the tutorial to run the install under your normal user. (http://www.limit-point.com/Utilities/LaunchAsRoot.html).

Thanks Thukano for your help.
