C6500 Flipping blade (drum)

[twinax]

Hi Guy's

As you know there are a lot of problem with the drum unit of C6500. Several error code 22xx and mainly flipping blade in a short time (less than 2000 prints).

Do you have any information about this problem or some workarrounds to reduce (maybe solve) it?

Thanks for your help.

There are new drum units to correct the problem.

I had the production print specialist from PTSC with me today visiting some of our production print sites and this was one thing i brought up with him, he knew nothing about new drum units and told me it was still under investigation. do you have any more info about them because at the minute i am using the old drums i have saved up for emergencies because i don't want to go back to them 2 hours later.

Hello,

Thank you for your replies.

I've any information about new drum.

Today I visited a customer site, and I remove one spring (rear one, on all colors) onto the cleaning blade.

We have printed 3000 prints without any problem. (no error code, no flipping blade, and no print quality problem like lines).

The engine is under survey for 2 or 3 days. After that if that's good I will modify all engines.

I keep you informed about the result.

Kind regards,

Wrong info. OOOps... Does anyone have any pictures for this procedure?

There is a new drum unit called DU102B but this is only supposed to be for black and to solve the black mark problem not blade flipping. To stop flipping cut the corner of each edge of the blade(about 1 mm). Let me know how that works, oh and heaps of setting powder.

result of removed spring

Hi,

If the customer print only text it works with only one spring, but if you print solid color or half color, there is balancing problem between upper and lower print (more dark on operator side than the other.)

Next step : I will try to cut the corner as mentionned.

Thanks you

We got an email today from our KM rep. This is what it said

To All,
In regards to the C6500 blade flipping issue, the following is the latest update. On all machines experiencing this issue please make sure you have a SSD ticket open for each machine and update the ticket with the results of the following solution. This feedback is critical to ensure all available information will be provided to those addressing this issue.Thank you for your patience and in advance for your feedback.

Please have the technicians install this firmware and report the results via the Hotline. This firmware will create toner bands in-between the pages during the copy run to help lubricate the blade. Please set DipSW 13-2=0 and DipSW 13-3=1.

Please note that this is a temporary workaround and they are still trying to determine the root cause of the problem.

A solution has been created.

I looked and there is a special firmware that was released today. You can find it on KM website. I have attached the release notes

I also have had c6500 drum blade flips about 8k old. Fixed by fitting c500 drum application roller and pad to c6500 drum unit.

Running 2 machines both sets of drum units fitted with these parts both now done over 300k no flips.

The application roller on the c500 has a more dense coating hense better lubrication

We haven't had any blades flip lately but the ones we did we replaced the blade and had no problems since.

I wonder if this special firmware can be installed with version 41?
I have a few machines with the finishers that version 41 helps.
I'm tempted to roll back to 40 and install the patch.
The machines aren't going down because of the finisher exit.

C 6500 Status Quo !

Hello Guy's

The problem (flipping blade) is growing up without any solution or workaround at this moment. the latest version for C6500 V.41 but the adjustement to avoid this problem doesn't work.
I tested several thing but nothing works well.

IF you have more information please tell me!

I do ti if I've it.

Regards,

Blade flip

Blade flip may be addressed by;

1. Cut corners of the blade at a 45 degree angle
2. Apply carwax (spray on) to the drum surface, buff. This has worked for several dealers.
3. Use alot of setting powder and work the blade back and forth on it.
4. Use C500 blade pressure springs (reduced pressure).

KMBS is working with a new type of drum, they are not available as yet.
