IM C2500 not recognising toner after firmware update

[dave w]

NEW UPDATE

I removed all 4 toners from the customer and placed them in a new IMC2000 we have here in the workshop.

Same issue, so has to be the toner chip. SPOOKY

new set of toners have been ordered and hopefully that will do it.

Thanks all

the big question is why? and after a firmware update. Lets hope that was a one off case.

It's just one of those stupidities. I had an MPC3003 that the side door harness was replaced on due to jam 024. When the harness was replaced, it threw a really odd and spurious code that turned out to be one of the toner bottles. Put the old harness back on and it worked fine.

Compatible or Original Toners, if the chip is not read correctly causes rare errors in some machines.
I had a similar problem in an MP C5502, the connector of the Cyan chip, had the tabs crooked, causing a strange "short", and the machine indicated that the Image Units (all) and the Fusion Unit, were not installed correctly.

That NV Ram clear method helped me several times with the older series but good to know it was the chip (better that than a faulty contacts inside the MFP we had a lot with the MPC305 back then).

To be honest - I have never done a NV Ram Clear and used a Birth Sheet to re input all the details, so i was relieved to see it was the Toner chip. PHEW!

Luckily it wasn't neccessary to re-enter the values manually if you used the backup/restore function via sd card. For some reason the detection error did not re-appear after restoring the data so kind of a quick fix actually.

I find it hard to believe that a firmware upgrade would cause such drastic problem.
It's not that i don't believe you, i'm just asking myself how this machine would damage it's own tonerchip.

I understand you, its bizzare, But all was ok until the firmware was updated.

I did the print test and then updated the firmware
