Disabling USB ports on Pixma Pro-1

[SeaBee63]

I'm planning to implement a couple of these printers in a post-secondary education lab setting and need to disable, lock or block the USB ports to prevent un-chargable prints. They will be connected to the network and a PaperCut server to recover costs.

How difficult is it to remove the case far enough to unplug the USB internals? Is there a service manual or take-apart guide available somewhere?

If that's not an option, I can find a physical lock for the front "A" port and I could drill a couple holes and use a small padlock for the rear "B" port, but i'd rather not permanently modify the cases.

I wouldn’t go pulling this beast apart just to stop some little toe rag from interfering with the USB socket, try this idea before you go drilling holes in the case also, it includes a video demo.

I know about those solutions for the front "A" port; my problem is with the "B" port on the back. There doesn't seem to be a 'lock' solution for them.

OK, Here is how to remove the rear panel from the printer !

You only need to remove the right hand panel, nothing else, note the position of the On/Off button,
Just slip a screwdriver under the position indicated.

Then release the 3 clips from the back panel (Right side only) where the USB plug is situated and your done.

You can glue a piece of plastic on the inside of the back cover to blank the USB socket, then reassemble; care should be taken for the repositioning of the On/Off button !

Thanks for that info. Not only was I able to get that rear panel off, but while I was in there I was able to track down and disconnect the cable/connector for the front USB port.

My problems have found a solution within a couple of hours! Gotta love the internet! ...and a big THANKS to The Hat!
