How to uninstall print drivers Canon MF4150 issues

Question

Hello all, I am having a nightmare of a time getting my Canon MF4150 to print. It looks from all of the threads on here it was a less than ideal choice for a Mac owner.
When I first bought the unit I managed to get it to print, everything seemed peachy.
Problems arose when I wanted to use the unit to scan. I downloaded a variety of third party software and drivers in an attempt to get the scan function working. I had mixed results, and this process seemed to upset the printing side of things. Once I scanned a document, the printer would then not work.
I abandoned the idea of scanning through the MF4150 and have gone back to dedicated Epson scanner.
Since then I have not had any luck getting the printer to print again.
I have gone through all the MF4150 related threads on these boards I can find, and followed the process to installed outlined here - https://discussions.apple.com/message/7657893#7657893 but to no avail.
I really just want this thing to print and it's driving me nuts.
I have the printer attached directly to my MacBook Pro running 10.5.2. I'm not trying to print through the Airport.
I would like to know how to completely uninstall any UFR II drivers and related software / information and start this process from the beginning again.
So far, using the answer provided by PAHU here https://discussions.apple.com/message/7657893#7657893
I have -
1. Open System Preferences > Print & Fax
> DONE
2. Select the MF4150 printer and press the minus " - " button to remove the printer. Do the same to any other printers that are in the printer list.
> DONE
3. Hold down the Control key and click in the empty printer list. A window showing 'Reset printing system' will display. Click this.
> DONE
4. Close the Print & Fax utility.
> DONE
5. Run the Canon UFR2 v1.70 installer and select Uninstall when the Easy Install menu appears
> This is where I get snagged. I'm not offered a Uninstall option. I have attached a screen grab of the window I am presented with. I am currently trying the "o1141enx_m_ufr224" version of the UFR driver. I have continued to complete the points below regardless of the fact i cannot uninstall.
6. Restart the Mac and run the v1.70 installer again to add the UFR2 files back onto your Mac
7. Go to Applications > Utilities and open Disk Utility. Select the Mac OS X partition in the left pane and select 'Repair Disk Permissions'. When this has completed, quit Disk Utility
8. Open Print & Fax and add the MF4270 again
9. Open TextEdit, type some simple text and select to print.
10. Report back if the above doesn't get you printing.
I have also attach a screen grab of the process I go through when adding the printer.
Any help with this would be amazing. I've tried everything I can think of.
My latest idea is to try and remove any trace of previous printer drivers and go from there. You can see in my list of available drivers in the file attached I now have all sorts of UFR drivers in the list.
Again, if anyone can throw me a line on this that would be great.
Thanks & Regards

Hello Coz,
It's been a while since you've posted, I hope you have not given up.  I was having grief with my MF4150 as well, but got it working.  There is a more current driver - search for Mac_UFRII_V230_uk_EN and install it.
Then, when you go to add your printer through System Preferences > Print & Fax, make sure you click the "default" icon in the top of the dialog.  It should show your Canon MF 4100 series , then use the bottom drop down menu to choose your driver and select Canno MF410 Series UFRII LT (UK) from the list.
