Anybody seen this on a Bizhub 600

Machine will make 1 perfect copy at a time. If you ask for two, the second page will be stopped in the turnover section of the fuser, with some marks on the page, but not the image you copied. The second sheet of 11/17 will stop at the entrance of the fuser. Tech support said it could be the power supply???

Jam counter code? Have you stopped the copy under the drum? is The image there? Could be a lot of things. What have you tried?

[fixthecopier]

There is no image on the drum on the second blank copy. The call is another techs at the shop at the end of day. I do not believe the jam is the issue as much as the missing image. The KM district service rep said that the power supplies do stupid things when damaged. I was just wondering if any body else had heard of this. I would think it would be the image control board. It is as though after passing the paper to the drum, it doesn't make the copy, and then does not think the paper should be there so it jams at the next sensor. There are marks on the paper as if some electrical discharge is taking place. No mater what drawer you feed from, or paper size, or no matter how many you ask for, first copy perfect, second sheet has no image and stops in fuser.

Perhaps a problem with memory...or the hard disk...

disable the hard disk and/or swap memory sticks and try again...

[aleksander]

try to change the memory and rewrite the firmware. I hope it can help you.

[kingpd@businessprints.net]

Try giving the machine a few light slams and talking nasty to it...you'd be surprised that this can actually "fix" things...

If you have dialed up multiple copies say 10? Do you get the same results? One exits and one at the turn over? There should be a 3 rd sheet. If you only have one in the machine not 2 then I would check the sensor on the bypass assembly PS36 Loop Sensor. When you remove the bypass it is right in the middle. I have seen some strange things happen if that sensor gets sluggish.

[fixthecopier]

Anything more than 1 copy has the same results, stops in the fuser with no image, there is no third sheet.

[pepper38_cnd]

There should be a third sheet in multiple copy mode sheets are normaly fed fed about 3 inches apart, timing is controlled by sheet feed sensor if it didin't work your page would stop before the drum, loop sensor and reg sensor if either of these fails the next sheet will not feed.

Sounds more like a ADUDB issue to me.....

I dunno if you're trying to feed from the RADF nor if that also happens with internal prints, but here's something I found on the 7165 troubleshooting that is remarkably close to your description:

DESCRIPTION: DF316, when copying 11x17 or 8.5x14 originals from the RADF, a misfeed occurs and 2 sheets exit (1 copy and 1 blank copy).

CAUSE: Overhead lighting is interfering with the original length detection performed by original length sensors (PS309) and (PS310).

SOLUTION: If, the machine cannot be moved to another location, order a sensor filter kit (p/n U193-0030) and install the original sensor filters above (PS309) and (PS310), which will block light frequencies that cause the sensors to react incorrectly. Attach the filter sheets above the sensors by using transparent tape. Since the sensors are located in a recessed area of the RADF feed tray, the tape and filter will not interfere with feeding of originals.
Note: A quantity of two (2) filter sheets is included with each sensor filter kit.

Thanks for all of the input. As I stated earlier it is another techs call and he was not able to go back to it today. He did add that he tried all sizes of paper with the same results, only difference is the 8and a half stops in the turnover and the longer paper stops in the fuser. I mentioned the length sensors and he has had that issue before and has eliminated it as a possibility. It seems he noticed cola stains on the back before leaving the call and that is what led the district service rep to think it was the power supply.

[fixthecopier]

To update, the tech flashed it with new firmware and it worked ..... for about 20 pages, then went back to doing the same thing.

[pepper38_cnd]

I'm still sticking with the loop or the reg sensors, but a sticking reg clutch would do it too! So would the ADUBD as was mentioned before. You haven't mentioned the jam code yet? J1701 thru J1704 deal with loop and reg sensor.

seen this just last week, turned out to be the priner contol board
