i have a 9500 km printer that the counter went to zero and is now counting up all over, we have not done anything to the printer at all any ideals, the last meter we have is about 900k sence that last meter it cleared its self

I have also seen this so I am interested in the answer to this??

tech support told me the battery or power spike? machine on a surge, battery will lose after long time out

We had this occur on a few of the smaller FS4000s and the rest in this series. We were instructed to update the firmware to the latest level available at the time and had KMA support do a remote session and they are able to re-enter the total count based off the drum counter if the drum had not been replaced yet. I would update the firmware and see if you can get a reasonable counter number that is close based off of unit counters for this printer and have KMA support put the total counter back up to where it should be.

Their is a firmware upgrade for this problem from along time ago. You probably lost the serial number at the same time. In fact it probably lost the country code when it comes to paper size. I'm not sure if tech support can put the serial number back in and the print count.

You can put page count and SN# back to original – one of the way, is doing firmware update – but you need to do it in 2 stages – load Engine firmware first – power off/on– then load System.
Alternatively you will need Kyocera tech – sometime it is possible to log on to the machine remotely and send FRPO command, unfortunately I can not list this command – so please do not ask . The FRPO command will work on any machine, I’ve done it countless time on fs-2000-6950 when firmware update did not work and stopped working on USB ( lost SN#)

Ditto what Vladimir said. The FRPO commands are "top secret" but if you're lucky, your tech rep (if you have one anymore) might MIGHT slip them to you under the table. You can get an accurate meter count to reprogram by running the service status page. It should show you how many clicks are on the drum unit (this is an alphanumeric code... A=0, B=1, C=2, etc...). You can crossreference that with the history of the machine (last time the drum was replaced which is usually a pm of course), then add the current drum count to the meter reading you took at the time of replacement. Then send the FRPO command to reprogram. Your tech rep will do this if he has to come... ours had to come dozens of times to do this until I got graced with the top level security clearance to handle it myself.
