Hi, from what I've read here: Error Codes Konica Minolta bizhub 163 , this is a Fusing Cooling Fan Motor malfunction, which suggests, I'm afraid, that you have to have it serviced. Kind regards, Jon Erik

Remove the Compact Flash Cover. Located Right side next to where the network cable is installed. Remove the cover, using a small screw driver or small plastic stick depress black button gently. Called the Warm Restart switch. When "." appears at the center on the left-hand side of the screen, enter "3" from the via 10-Key Pad. Enter the 8-digit service code and touch [END]. (Default value: 00000000) if required. Touch [Touch Panel Adjustment] from the Initial mode screen. Following the arrow mark, touch the four points (+) sequentially on the screen using a pen. DO NOT USE A SHARPE POINT!!!!!. Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/normanj_7893313f0751935f

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 requir
e 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.

All The Best: Pineworks

I know this is and old post, but I came across this issue today and this post is the first that came up in my Google searches, and three was no good response. So I thought I would post an update.[Sorry Zaheer, I know you were trying to be helpful, but your response was a little too vague and in the end, inaccurate]1) Go to the printer's Web Connection by typing the IP address in a browser. 2) Make sure you are on the "System" tab (Blue) at the top3) Click on the "Detail" link on the side menu4) Click on the "Interface Info" sub link* Notice that you do NOT log into the Admin portion of the Web Connection. That will only confuse you.This will show various stats, one of which is the MAC Address of the machine. It seems like this would be better placed in the Network tab under the admin interface, but here it is.Hope this helps someone.

Did you replace them????? The machine uses the counter to determine certain voltage assignment to those parts so if you say you reset the drum counter to Zero then machine will assume it has a new drum and assign the required voltage for a new drum since its not a new drum because all you did is reset the counter with out replacing it ,you get bad copy issues codes and issues.

Sir/Mam, You hit a serious code, noting can be done, this code requires a tech to come out and remove a chip inside the machine, which is then sent to Konica Minolta, then on to the US SECRET SERVICE since someone attempted to counter fit US currency!!!!!!!!!!!, until the US Secret Service determines what was done the machine stays inoperative , once what happen is determined tech will come out reinstall the chip reload firmware, and .NEVER EVER PLACE ANY CURRENCY ON A COPIER all the machine now a day have Bank Note chips.
