bizhub 223 deveroper unit question

[brent]

so I went and replaced developer and drum unit today on a machine. everything worked great but I did notice lines on the copies before and after the dv change. now that I did that. I need to replace the dv unit. at this point do I need to just put in fresh developer into a new dv unit. and run the function? I am hoping to not have to replace the drum unit as well again. just curious as it is very early in the drum live (under 300 total prints)
thanks

Are you sure that it is the dev unit causing the problem? What about the fuser heat roller? Also have a look at the transfer roller as they seem to wear the horns very easily and mark the drum. You should be able to just change out the dev tank without the drum if needed. Remember to do all the adjustments before and after.

Re: bizhub 223 deveroper unit question

i've dumped almost new dev into a unit for unexpected 2557 codes.

bring everything, but it can't hurt to try

Re: bizhub 223 deveroper unit question

Those drums are very durable. I'd give it a visual inspection. If there is physical wear you'll see it.

Do you see bare spots in the mag roller coverage? Perhaps it just needs a good vacuuming, and to run some paper between the S-blade and mag roller? How many clicks on the machine? I have machines over 500K and have not had to change a developing unit yet. I think the warning comes on at 550K. =^..^=

Re: bizhub 223 deveroper unit question

We have a 223 that when I did the 1st PM I noticed that it had the old style black DS rollers and not the white ones w/bearing like our other 3 series models do.

If it does they may be worn down.

Re: bizhub 223 deveroper unit question

I must have been high yesterday. Iwent and did another drum change on a 423 today. and same thing. got it all back together. it is fine. just went and checked out the one from yesterday. it is fine.
should have looked before I leaped.

gotta love this learning curve. I am not really happy with the 423 223 machines.
because pm cycle is half of that of the bizhub 421 series. fusers are shit. got 100k out of the last one.
carefully every pm always keep pic fingers cleaned in fuser. they just seem a little bit light weight
but oh well. what can ya do? sorry for venting.

Re: bizhub 223 deveroper unit question

Love the 200 series minus crappy dev units.

We had some 200/350 series that would go 500k + before the fuser showed marks at the thermostat...we have a 423 showing marks at the 2nd PM so something has happened for sure.

Don't care much for the crappy sped up beyond max 7020 drum and developer used on the 420-501s, and I really hate those crappy felt/foam drum seals they use. You have to keep a close eye on those or they will bite you.

Re: bizhub 223 deveroper unit question

craig. it is too funny that we know all the quirks. and we can't vent to the customers about this crap.
I love this forum. I have nobody else to vent to about my work. becuase nobody else around here works on this. I am basicallly a one man show. thank gosh for this site and you willing to share and listen. I hope that I can help people as well, as long as they are not in my area... gotta make a living some how

Re: bizhub 223 deveroper unit question

It's rare to get more than 240K from the fusers. I'm hoping to start changing out the upper rollers on some of these spare units to get another 240K. =^..^=

Re: bizhub 223 deveroper unit question

I hate the 421 series. Big piece o crap. The 423 is great except for the old style drum and dev unit. I expect this series the last to use this engine. Could be wrong though.

Re: bizhub 223 deveroper unit question

I have several of this series out there and I have only had 2 odd problems. One was an ADF issue....another was a board blown due to the polarities being reversed on the electrical outlet...irony is that this was at an electrical supply store. Other than that I've done 2 PMs on a machine at a school that uses the crap out of it.....

Re: bizhub 223 deveroper unit question

We had a 200 that saw a lot of use go 6 PM-PM cycles without a single other call, we have had 200s doing many single prints eat developing units and destroy the drum before the 1st PM.

With the white collars in place on the XX3 series I think they have a lot of potential imo, but now the fusers seem to be a weak link.

The 420-501 PMs take forever !! 200 series quick and easy.

Hey Guys'
Not to be funny but I have a developer kit that I ordered for my Bizhub 223, I was wondering, where it goes in the printer ? Does it go inside of the drum unit ?
Thanks for all help.

There are specific steps in all this. You just can't stick these parts in the machine and it work. What did you order exactly, the developer unit?. I hope you also have a package of developer. And usually you replace drum same time as developer. You have to clear the life counters, install the unit then you have to run TCR adjustment in service mode.
