Oh, I just realised, you are saying its connected directly to the computer... USB? means its may not be connected to your network in any way... so then you can't really connect to it via network...

I'd have to check what you can do in that case... Can you connect it to a network? That would be easiest...

Just a note, I also booted/rebooted this printer many many times, and was able to print once in a while even with the error... but it was rare...

Yes, connecting to a network allowed me to verify the firmware version which is R5.03

Does anyone know, how does one enter 'upgrade mode' on LBP7750 prior to upgrading firmware?
There is no suitable option in the venue, is there and key combination one needs to press?

Re: LBP 7750 cdn, code E078-0001

In the printer menu...

set the printert to "offline"

press "settings"

select "user maintenance"

select "update firmware"

select "usb" or " standard network"

Hope that helps...

Thank you. The trick here is to set the printer to "offline" otherwise the menu does not populate.

I can confirm upgrading the firmware resolved this paralysing error code.
Thank you airsoftsnake for patiently walking me through it.

Sorry for opening up this topic again. I have the exact same error code (seemingly appeared out of nowhere) on our 7750cdn. Obviously, I would hope to also fix the issue with a firmware update. Our machine is currently running R5.05. However, I haven't found a way to update.
* The device's old version of Remote UI does not seem to offer an upgrade option. (Or does it?)
* I do not seem to find a firmware file on any of the CANON support pages
* I am able to put the machine in "UPDATEMODE READY" status in "standard network" as described above. Does it then download anything automatically or are further actions required?

Any help is appreciated.
Thx, Henry.

Hi Henry,

I'm only seeing your post now - hope you've resolved the issue by now, but if not, to answer your questions:
- yes, you need to upgrade the firmware - I have version R7.10 on mine
- yes, Canon is not helpful in locating the firmware update file, however airosoftsnake was kind enough to share it - I no longer have it handy unfortunately
- yes, all you do is run the upgrade when the machine is set to be updated and then magically the error is gone.

Hope this helps, best of luck!

[airsoftsnake]

Still have the file, just chat me, and will get it to you. Sorry for my late responses, I'm not always seeing the private messages here... they go to spam sometimes.
