Has anyone had the HV Charger Error recently.

We had one machine out of the box doing this,the machine would start up and say warming up and then pop the code (e-34 bias on KIP display). I ran through removing and reinserting the coronas and DV unit, nothing. So I decided to disconnect each wire(one at a time),off the hv board, powered off/on, and when I got to the green connector on that board and removed it the machine came to ready. Plugged it back in and it popped the code again. Called the regional rep., he came out and found that the drum collar that held the drum in place was loose from the factory. So no biggie, right, until now.
I had a different machine that was just installed two weeks ago do this. The machine has a 1000 ft on it. I checked all the switches for the toner door and clam shell. They all checked out fine. I took all the components out of the machine and still no luck. Checked if the collars tight, they were. I did what Kyocera told me to do and did a clear through the KIP interface and still no luck. It was a E-34 bias issue through the KIP interface display. So as a last resort, I went back to that same connector on that HV board and removed it, powered the machine on and it came to ready, plugged the connector back in and it works. Shut the machine off and on, works, pulled power to it, works, tried copies, works, prints, works, scans, works.

My question to everyone is: is these machines just junk or is it just me? Has anyone ran acrossed this? We are selling more and more of these, what other stuff have people ran across?

I can't add much to your particular problem...but I've only 3 of these out (all with low counts, say 3-4k in a year). 2 out of 3 had the power supplies in the print systems fail. My rep has been out to modify the heat roller drive (twice...one mod then yet another), upgrade firmware, upgrade bios, install warning lables. He said some of the power supply failures also took out mother boards.

Just some of what I've experienced.

recently i did the 18000 linear feet pm kit on one of these machines and after replaceing all the parts with the step by step instructions the e-034 code came up on the service display, i am guessing that is also reffered to as the kip display, i have checked all the connectors, filled it with a started kit toner, checked the voltages on the hv board and am now at wits end as to what could be causing this. I see that there is a history of this particular code with this model. any information you could pass on would be greatly apperciated becuase it has been down now for three days and the customer is becoming highly irritated. thank you for any information.

A suggestion if I may. The HV cables that supply bias etc to the developer tank come from a small gren connection board on the right of the machine. This board has a small connecting cable with smaller spade connectors and is about 2.5 inch's long. If you disconnect this cable and the machine comes to ready then the problem is the developer tank. I have had this on 2 machines. If you want me to get the connector numbers, as my explanation may not be the best., I can do that .....

The only problems that we have had was the fuser drive. After putting in the mod for the fuser we have not had any problems.

I have a 3650 that is doing the same as copyjunkies machine. Has anyone found out what happens when the 034 bias error code comes up after doing the pm on the dev unit?

Did you find a answer to this ?

The KM3650 is basically a KIP 3000 right?

If you're getting 034 after PMing the dev unit, check the following:

1)Remove the black cover with the contacts on the right side of the developer unit. If you put any grease on the roller ends or contacts, remove it.

2)Make sure that the white spacer is in place between the regulating roller drive gear and bearing. Make sure the drive pin in in place under (inside) the gear. Proper re-assembly of the DV unit is critical, and these machines (my experience is on KIP 3000s) are stupidly sensitive to bias issues.

3)Take your meter and make sure you have continuity between the middle of the regulating roller and the end of the roller; put your meter lead on the very end face of the roller, not in the little detent that is there. Then, make sure that you do NOT have continuity between the end-face of the roller and the 10mm or so area on the side-ends of the regulating roller; that area between the end of the roller and the clear plastic spacer built into the regulating roller. You should also NOT have continuity between the middle of the regulating roller and the bearings. The only place you should have continuity with the end-face of the regulating roller is the middle of the regulating roller.

4)If everything above is good, prepare to reinstall the black contacts housing for the right side of the developer unit. Make sure that all the contacts on the inside will be firmly touching the roller ends and points when it is reinstalled. Gently bend the tabs a little if needed. Reinstall this housing, and check continuity; you SHOULD have continuity between the middle of the regulating roller and the copper contact on the outside of the housing that touches the regulating roller.

Reinstall and try. If you're getting incorrect continuity measurements, the regulating roller probably needs to be replaced. If the machine was working fine prior to the PM and is throwing 034s since the PM, the developer unit was likely not reassembled correctly. The position and order of the spacers, clips, washers, etc is very important.

Aside from that, I would think probably HVPS.
