Hi

Read through this as we are having the same kind of problem with a C451. It now has a surge protector and network filter on it along with most recent R6 f/w. Its had the MFP and NVRAM checked and a new PSB put on it. Still always locks up in the morning.

The ops panel displays the following message when its locked up "Due to an alert the panel is illuminated" - I have never seen this. Have any of you guys??

I'm not sure if we have took the m/c out of sleep mode so could try that. However, the customer has several konicas with the same locking up problem, not just C451.

They also changed the network service provider and recently had a brand new generator installed next to the building.

Any suggestions??

if it was just one machine doing this, I would say that there was likely a problem specific to that machine, though not necessarily that machine. The previous suggestions would at some point resolve issues like this.

In the case of multiple machines and some of the description of the environment you mentioned, power is quite likely the fault.

Obtain a power line monitor and plug it in where the machine is and review what the power line was doing for a day or two. This is not always practical to obtain one, they are expensive. Sometimes a power conditioner will resolve problems related to poor power, but it will not resolve problems where there is insufficient power getting to the machine. For example, if the line is supposed to be 120v and is constantly below 110v over a 24 hour period, the machine will most likely have some kind of failure at some point due to power sags (someone turns on their computer, or runs the microwave). The only sure way to know for certain in such cases is with a line monitor.
