iR105 - mind of its own

[TA_Tech]

Hi to all techs around the world

I have a very interesting problem with an iR105. This machine worked fine for 3 years, and has done millions of copies, but last week the biatch started acting up. It had 2 ID codes registered on it, one for the sole user of this machine, the other for the service boys. One day this machine decided screw this, I'm deleting these 2 ID's, and then I'm gonna create 999 of my own ID's. Not only that, but all 999 ID's start with a - (minus), they have random 6 digit passwords (also starting with -), and a copy limit of 999999.

You can try till the tip of your finger has a callus, but you cant log in using any of these ID's. Why?, because you cant put a minus at the beginning. Even better - no access to the menus.

First up - clear the ID code via service mode. which works just fine, you can get into the menu and into Dept ID Management to view all these wonderful codes. NOW, with ID codes disabled, if you cycle the power, she decides that, I want to re-enable the codes... back to square one.

Step two - the firmware upgrade - good luck, because she don't store IP addresses. As soon as you cycle the power IP's a reset to 0.0.0.0. Enter Step 3, the USB to parallel cable - IT WORKS!!!! Now with System, boot, Rui, Language, etc up to the latest level at least she's not forgetfull anymore and remembers to store the IP Address, but the msytery codes are still there, minus and all, and she still deletes whatever codes you store and replaces them with her own, and still re-enables ID codes if you disable them and power cycle.

So, I'm thinking to myself... "wonder if she'll be impressed if i delete all her codes". Option 1... via panel - very arse numbing, option 2 - via RUI. Option 2 it is! Only thing is the RUI doesn't seem to see all her codes, so no editing, deleting, or any of that fun stuff. Also RUI asks for Admin ID and Password. This time round, being from a computer you can start the code and the password with the elusive minus, but alas, she knows its me and wont let me in. Clear the PWD, connect with the RUI, and like i said two sentences ago - the codes aren't there. Finally option 2 - delete ID's via panel - Who needs Xbox when you got this great game... this will keep the kids busy for hours. FINALLY, all codes deleted, the original 2 codes re-registered, and about a 100 power cycles later, she seems happy... until 2 days later, which is today.

Anybody with any bright ideas???????

sounds like a malicious software attack, but no I have never seen that.

Sounds like a board has gone crazy or you have AC arc somewhere.Have you booted it up with all the internals pulled out?Cleaned the boot rom and memory?

[20YRSEXP]

I would have to agree with Kopy, I have never seen a virus infect a Canon (doesn't mean it couldn't)but not likely. I don't think it is an AC short it would throw the circuit breaker. Maybe a DC short, But the Main controller would be your most likely culprit.

It sounds like a main controller is starting to go bad. Did you try clearing MMI?

I kinda like this as well,,, but what about the keep alive battery on the controller board,,, if that started to go south, it could drive the settings crazy. The reboot and crazyness returns smells of this... 105's have been around a LONG time, and I can think of no error that has ever pointed to the battery. Give it a whirl,, and let us know of your next exciting adventure in button pushing land

i go with mrfixit : since you said the ip's go back to 0.0.0.0 first check the battery.

[mjarbar]

I'll put in my 2 cents with the battery, as this acts in the same way as the BIOS battery in your computer. Try replacing that before you start spending out on DC controllers and the like.

Best of luck

After doing some research on the main controller there is mention that may be true about the battery. It may cause a problem with dept id, Ip address lost and date&time. If the battery reads less than 3 Volts DC it should be replaced.

I think mrfixit nailed your problem.
