Lanier LD122

[tr21x]

I have A Lanier LD122 that has an issue of the dev sticking to the drum. I have upgraded the firmware, also initialized the dev after replaceing the the drum letting the machine do it's initialization. I have replaced the pcu twice since the orginal drum started the problem. You cannot see the dev on the page or feel it with your fingers but if you take the first two copies out and rub them against one another you can feal it in between the pages. I have vacumed, blown out all crevices of machine, changed transfer assembly. Also have checked quenching lamp and high voltage board(per Ricoh tech support)they checked out fine. Yes I tried the drums in other contract machines and they worked fine.

have the developer bias and or charge roller voltage been messed with?

No checked all in sp modes and all are in spec range

Hey, you said that you vaccumed all the corners and folds right? Does that mean that the previous PCU leaked into the machine?

When this happens (I'm sure you know though) it can be almost impossible to get all the toner and developer out of the inside of the machine and it will leak into the drawers.

Now, did you check to make sure that the drum ground it good? Just like the 5635/45 and the LD060's used to do with a bad drum ground, it would pull developer....

Ricoh tech support is about worthless most of the time.. granted there are sometimes they can lead you into the right direction but you have to remember they are ex techs from years back and they depend on current tech fixes.

I personally have not experienced the Ld122/27 series copier pulling developer with a new PCU, but I know that the 5635/45 pulls when the developer is bad and/or the drum ground is faulty. Hope this helps

I have had customers who put Ricoh analog toner into these machines and get this type of problem. But usually it won't show up until the machine is also coating the transfer roller so badly during process control that the reverse of the lead edge of the first copy in a set is almost black.

Also, I hope these are OEM PCU's. My former employer tried to use aftermarket rebuilt PCU's with a bright green drum, but I don't know whose they were. After all of them failed within a few K, we went back to OEM.

Drum Ground.

Check it with while turning the drum shaft. Ricoh says less than 50 ohms is good, but I'd say replace it if it's not single digits or bounces around at all while you turn the shaft.

And make sure you use NEW OEM PCU's - Ricoh even tried rebuilding them for a while and couldn't make it work
