If the tester your using is able to monitor for an extended time, let it run for a day or two while they are using the machine. Then you can tell them with confidence the tech is full of crap and is passing the buck. If you start telling them that before you have done anything then it will look like your just trying to pass the buck too.

When you are looking at voltage spikes what is normal and what would be considered a problem and would need a filter.

The manufacturer would have to determine that number. It should be in the specs or on the web pdf for the printer. Ask the tech he should be able to give you a number. Make sure you ask in front of the customer so he looks like an idiot.
 
Interestingly enough EC&M has an article in their Nov. 2008 issue titled "When does poor power quality cause electronic failures?" I don't have a link to it as I need to get out of here-- have a good day.
 
I'd make sure it's not on a general purpose recep circuit first. I know those big copiers like a dedicated circuit. Then go from there.

Jakewhis:

What is the error that is indicated by the error code?

Is this a standalone copy machine? Or a machine that receives data from somewhere else? If it receives data from somwhere else, then what is the communication method? RS232, USB, fiber, Ethernet, parallel, etc?

If this machine is run with no external connection is there an error? Can you run self test prints without error when there is no external connection?

How often does this machine error?

If there are no errors when it is disconnected from any external communication path, then if you use a battery powered laptop, no AC power to the laptop, to supply data to the machine are there any errors?

The printers usually cause the problem for other devices when the heaters cycle before printing or every few seconds or after starting. Not an upword spike in voltage but a drop. Is anything else on this circuit?

After looking more into it today, I noticed that she was running two smaller printers, a computer and a heater on the same circuit. I was surprised that the circuit did not trip.

The two other printers and the PC work OK?
And yet the tech says "it goes into error mode" and blames the supply?
