New MP4000 Dev Unit

[Jomama46]

I agree Wishbone. Further, how could they release this pig.. We have reports of problems way before PM time. WTF?
I feel screwed by Ricoh! They dont give a shit, let the peons sort out our problems!

[nmfaxman]

Has anybody regapped the Doctor blade?
I have found the rear @ a loose .4mm and the front as much as .9mm.
The buildup is in the front because the pressure of the brush against the drum fuses the toner to the mag roller.
I have re-gapped my machines to .35mm and the buildup takes longer to buildup.
I am going to start regapping to .30mm and see if it doesn't go away all together.
The DV units are all the same design.
Pads, not roller to drum set distance.
Setting it at .35 I don't lose density and the machine stays cleaner longer.
A .30mm may make the drums last longer.

I wish Ricoh would scrap these models and design something new that works.
.

Sorry Wishbone but I had a sticky beak at a sales presentation the other day that showed the Ricoh line up for the rest of the year. There are upgrades for the high volume B&W range, a new mid range colour and a A4 colour to compeat against printer engined colours but no replacement for the MP 4000/5000 so it looks like we are stuck with these turds for a while.
Depressing isn't it?

How are you doing this?

Feeler gauges. Or possibly voodoo.

Are we going to see New Toner, Dev & PCDU in April? These boxes need
alot of help.

[Kopyrtek]

They need an exorcisem at the VERY least!!
What a way to try and make cost on these POS's when Ricoh wont even try and help but by making you stock parts and MAYBE a new toner and DEV.As long as it is below $299 its your baby so you rock it and Ricoh takes your money to the bank!

"I wish Ricoh would scrap these models and design something new that works. You can't tell me with the great color products they have in this same segment that Ricoh can't do better. These have not run right since the very first 450's. You can put lipstick on a pig, but it's still a pig."

Most mono machines recycle toner, most color machines don't.

[Wishbone]

I understand that but that has nothing to do with designing a machine that put the pcu unit directly above the dv unit. Where did they expect paper dust to go? Oh and while we are at it lets incorperate a transfer belt unit that also houses the waste toner. Pure Genius!!!

[quote=Wishbone;67666]incorperate a transfer belt unit that also houses the waste toner.quote]

Thats an aspect of the design of these boxes that has allways puzzled me.
The Russian range have a simular setup with the drum over the dev unit but dont need a cleaning station on the transfer roller. The high volume B&Ws do have a cleaning station on the transfer belt but you are lucky to get a spoonful of toner in a million copies. To put such a large waste toner tank on the transfer belt of the Adonis range leads you to suspect that they expected it to chuck a lot of loose toner around from Day 1 of the initial design!

[DH1980]

Has anyone tried the new toner, Drum unit and New Developer unit?

[Pandy]

I guess the new units are scarce. The design worked a whole lot better in the older series, even if the pm was stretched. These last two series suck!

[aabarnes1]

We have tried all the mods ricoh have suggested and additional mods of our own ie drum grounding, the only thing that has workrd so far is using 2035 dev(Ican't recall the pn) and increasing the doctor blade gap. So far so good, no call backs on 6 of these machines that I've done

[Wishbone]

So you are using type 26 dev. in these machines? I figure that can go one of two ways.
