C252 didn't wake up this morning...

[DallasTech]

We have a customer that called in and said their copier has a black screen and will not do anything. We go check it out and sure enough, looks like power save mode, but no power save light on. We reset the machine, the hourglass comes up and you hear the machine start running. The screen will go black and will not respond to any buttons.

Machine will not boot up into service mode, but when I placed a CF card in it, like I am upgrading the firmware, it comes up to the screen telling me the card is invalid, so it's at least getting that far in the boot process before it dies. We replaced the NVRAM about a month ago and the machine was working fine until today.

The firmware on the machine was updated when I put in the NVRAM. Any ideas?

I was afraid to say it.

no boot

Does the machine have a hard drive? Had something similar and it turned out the hard drive had failed but the machine black screens before any codes come up, I would try disconnecting it and see what happens.

This model has HDD by default - HDD is not an option. So removing HDD is very interesting. Can C252 work without HDD?

It will work if you set System 2 > HDD to "unset", but there will be several limitations. For example Fax and Box will not work and I think also the address book.

Actually, one of the technicians put the main board in another machine and it came up with a firmware error. So we put the main board back into our machine and it started working again. but, it came up with a C-D370 code. I found a way to reset that through SSD. I reset all the data in the machine and powered it off and on. It came up with a hard drive error C-D003, iirc. So I disabled the hard drive and restarted it, it came back up with no errors this time. I ran about 30 color copies and they looked normal.

We are going to test the machine more, I am not confident in this machine working for extended periods of time.

Hello did you installed with the NV ram from the customer, CD370 is in combination with NV ram security data.
Set hard disk back too on and format the disk.
Did you do an NV ram reset with code our firmware.

make sure the flash card is 128 mb on the c252 it had to be a 128 mb card or would say invalid card

Hi. I had exactly this fault on a C250. You need to create a NVRAM recovery card (similar to firmware). Flash this, then perform firmware update. You may have to try this several times, as sometimes it doesn't "take" first time.

Are there any instruction on how to do this on SSD?

On the KM uk site, (infohub) it's all there. I'm not sure if the US site has such a section. I'll see if I can post a link later for you.
