bizhub 600 Drum Dusting Powder

Re: bizhub 600 Drum Dusting Powder

Hey blackcat, I thought I was the only one using toner from the back side of old blade and also turn drum each way back and forth a little until it feels smooth in the direction drum will be turning. I will probably regret saying this but I haven't had a blade flip for a very long time. If it works leave it alone....

Re: bizhub 600 Drum Dusting Powder

...hey guys,

Different topic same category.

I recently did a Full PM on the machine bh-600. Copy Count: 1.2 Million Copies.
Brand New: Developer Unit, Developer Powder, Drum Cylinder, Cleaning Blade, Toner Recycling Roller Unit, Main Charger Unit, Transfer/Separation Unit, Fuser Web. (Except TCSB).
After 13,000 copies, copies are getting dirty on the lower (bottom) edge of the paper (portrait orientation only). Like toner spots/or droppings, sometimes when there's a lot, you can actually wipe it off like a smudge.
And the droppings are very little but makes the copies dirty .

I do have another identical machine that drops more toner/developer on the top of the T/S Unit Front & Rear, but it doesn't make the copies dirty.

Which of the Charging (High Voltage) adjustment i should play around?
or is there another way or adjustment to control the dropping of the toner/developer?

oh temporary solution:
I did overhauled the Process Unit, Vacuumed out the toner below the blade and wiped the lower end of the developer unit (the side that meets the drum), and did the Drum Pecu... (Auto only).

I haven't done any manual adjustment on these machine myself.

still dropping, but no dirty copies for the moment.

Thanks in advance!

Re: bizhub 600 Drum Dusting Powder

i never use powder on these. never have never will i just used the blade setting mode. if you use the wrong powder it will kill the dev

is this maybe the reason why after 13K of brand new everything I'm getting toner/developer droppings on top of the T/S Unit?

Re: bizhub 600 Drum Dusting Powder

The only machines that seemed really prone to flipping blades were the Sharp AR-160, AR-161, AR-162 series. If you could manage to get through the first 4K or 5K copies after the new blade it would be OK. It didn't seem to matter what prime, what blade, what brand drum. I'm very glad to see those machines gone. =^..^=

Re: bizhub 600 Drum Dusting Powder

If I remember the cleaning roller & blade are loaded with setting powder right out of the box. Can't imagine how much more would be needed. That plus the setting mode has always worked for me. Never a blade flip.

If I remove the process unit to clean in between PM's, etc I always use a light coating of toner on the blade then do setting mode and rest of peculiarly adjustments.

I haven't used setting powder in several years. One less thing I have to breathe. Don't care what anyone says that shit can't be good for you. Besides I had enough white shit go up my nose back in my party days

thank you Mr. Copyman, same sentiments here. For the setting powder, i use them when i overhaul the Process Unit due to dirty copies and the parts are still under it's life. or if I'm not ready to replace them.

No, it's because it's a 600. You'll get to shovel out the S/T unit every visit. It's a toner-dumping machine. =^..^=

Mr. Copyman, what is your trick to have a clean safe transfer of toner powder from and old blade to a used drum per say? like how do you coat them nicely?
I wanted to ask on how to transfer to a blade, but i just realized, new blade comes with setting powder already...

Just align the contact edge of the cleaning blade with the backside of the old blade. In one smooth motion swipe it across the new blade. It will give you a small (1mm or less) ridge of toner right on the contact edge of the blade. Then mount the blade in the cleaning unit. When you insert the new drum rotate it carefully through the first couple rotations to make sure it doesn't grab. =^..^=

Perfect! I'll do this procedure if I'll be reusing a used blade to transfer the toner from one blade to another.
And I'll just rotate the new or used drum with the blade installed but on off position. (quite scary noh? i'm scared to do this.)

At least the new Blade And Toner Guide Roller (TRRU) comes with a setting powder. but the new Drum does not.

When i overhaul a Process Unit, i usually clean by wiping off the installed blade before reinstalling them, to get rid of you know, any particles that possibly will create lines on copies and gives us copy quality issues.
So when we do the blade to blade toner transfer, you don't think the unwanted particles will be transfer too?

And When changing the Main Charge Unit do you do the Process adjustment (Charging grid manual adjustment) (high voltage adjustment), Checking the charging grid voltage adjustment value as given in the drum flange section.Like Connecting a tester and Enter adjustment value manually?

Also on cleaning the TCSB sensor, what kind of Drum Cleaner we can use to clean the sensors with? does Konica Minolta sells one? or what alternative you guys use?

Lastly for the Power Supply pin/Roller shaft power supply section for the Toner Guide Roller - you recommend any electricity lubricant?

Sorry for all these questions...

thank you so in advance.

Sorry. It's getting late here so the answers will be brief:

I don't have a clue what you might mean by this.

No. I don't give it a thought. And you wipe off that nice drum prime powder that the manufacturer puts on the drum and blade for you? Why? If a blade is cleaning it's a really good idea to leave it alone, untouched, unless you're going to replace it. Wiping away those "unwanted" particles may well open up a gap in the wiper contact surface, creating a cleaning problem where you had none. The only time I wipe a cleaning blade is when 1) I don't have a replacement and 2) when it's not cleaning.

And When changing the Main Charge Unit do you do the Process adjustment (Charging grid manual adjustment) (high voltage adjustment), Checking the charging grid voltage adjustment value as given in the drum flange section.Like Connecting a tester and Enter adjustment value manually?...

Nope.

I hope you're not talking about the drum potential sensor. Just a few puffs of air from my puffer brush, and not refrigerant.

Lastly for the Power Supply pin/Roller shaft power supply section for the Toner Guide Roller - you recommend any electricity lubricant?

Do you mean the drum cleaner brush? No lubricant there. It will just mix with toner and make mud.

Re: bizhub 600 Drum Dusting Powder

Hey BC they are not that bad.
These machines need to run.
If they do 100K plus a month they seem ok.

Re: bizhub 600 Drum Dusting Powder

I have for the last 30 years used baby powder on Ricoh, sharp, Minolta, Konica and the combined, Xerox. I have never had any issues using baby powder and every one loves the smell plus its cheap enough just go to the travel isle and pick up baby powder for a dollar.

I'll do your toner blade to blade transfer trick if I'll be re-using an old good/used blade.
And If I'm out of drum setting powder, I'll just put the used drum back, install the used blade, with the blade on release position and rotate the drum manually to coat it with toner.

No. I don't give it a thought. And you wipe off that nice drum prime powder that the manufacturer puts on the drum and blade for you? Why?

When i overhaul a Process Unit prematurely, i don't necessarily replace it with new parts. Example when there is a CQ issue, reason: too much toner/Developer dumping.
So if i will re-use the blade i usually wipe of the toner on it to make sure to also remove the unwanted particles and usually put a setting powder before installing the use blade back.
I don't recall getting a new DR-710 drum with pre-coated setting powder.

The Toner Control Sensor Board underneath the Blade, there are two sensors there, book says to clean it with a cleaning pad with a Drum Cleaner, i usually just clean it with a blower brush.... but maybe Drum Cleaner is better?

The Toner Guide Roller besides the drum below the blade on the toner recycling area.
Book says to put electricity lubricant on the end shaft of the TGR. maybe for better electrical contact, Do you use any at all?

Thank you BC!
