May be the lid switch is faulty. There would be switch which confirm the Door is closed. If the switch is fault the the lid lock will not get activated and the the machine wont run. Try to find the switch and replace it. If you bypass it then you wont be able to close the door because the the lid lock will get activated before you close it.

Dear
The refill guy may done somthing which by pass the CRUM chip. At your end you may check the module attached to the toner cart.and test with alter that chip.
This may solve.
Before doing this pl.check the errorcode display .there might be other related problem with the machine.
Thanks.

Hi there.
Please try .
Try this.
The error code c3451 refers to a copier warm up error; the machine had not reached the correct temp within a specific time.
I bet it happened when you first switched on one morning.
Easy to reset and fault usually goes away.

To Reset switch machine off using the switch inside the front door, not the one on the control panel.
Whilst holding the UTILITY key down on the control panel switch the machine back on keeping the UTILITY key held down. Eventually a Trouble reset key will be displayed in the LCD screen, touch this, OK will be displayed then power the machine off and then back on.

This will reset the error code, if the code reoccurs then there will be a problem with the fuser unit in the machine, and this will require replacing.

Hope it did work for you.

Please come back and just gave a vote, it will gave me some satisfaction to know am helping some one so I will keep on helping.

Hello,

Try going to support.dell.com and entering your Service Tag. Then click on drivers and downloads and download and install the audio driver that they currently recommend for your machine. Sounds like a driver problem and something that wasn't set properly after the computer was reset.

I found mine did the same I pusshed the face and it came back on. It appears fault within circuitry of clock and will need to be replaced
