Ricoh 3030 with no toner in Type 1027 PCU...

Re: Ricoh 3030 with no toner in Type 1027 PCU...

The Type 1027 is recommended by Ricoh for those who don't want to PM the PCU. The only thing is you have to turn on SP 2804 New PCU Check.

2804 is a DFU in the manual/ but may work IF the push switch is fitted (?)
agree re the erase lamps but Dev bias seems logical due to gritty copies.

By golly, foo, you ought to get this one figured out. the response to this thread has been most excellent with tons of good suggestions. kinda nice when the best in the business give you this kind of attention. CTN rules.

Re: Ricoh 3030 with no toner in Type 1027 PCU...

LOL...I also have a Note 2. Had it a year...love it.

Yes there have been some great helpful ideas and I am returning to the machine this morning.
A lovely 75 mile drive to check over the list of ideas I have been given from everyone.

The Erase Lamp...whats the best way to test that. SP switch to turn it on and off with door open?
Just have not had to use that one.

Also whats a good ohm number to check for drum ground?

Thanks
Jeff

Erase lamp should be somewhere in SP5804

Drum earth, normally below 5 ohms (ish)

I would still look for the dev drive (bias) continuity as the probable cause, takes a while to strip, but sometimes it's worth "biting the bullet"

Whats the check for that? I assume it's a drive to gnd. check but where's the best place to get that done?

So silly...12 years and never had this kind of problem with a unit...oh yeah and it's 75 miles away.

Thanks

Re: Ricoh 3030 with no toner in Type 1027 PCU...

Have you cleaned the connector in the back of the machine, that the pcu plugs into???? BTW this machine originally had a rebuild able pcu in it, and by useing the 1027 pcu your cpc is now way above the manufacturers estimate. Been down that not profitable road before.

See attached,

Remove unit, push "B", release slowly. If it sticks, that's probably the problem.

if you can get to the front of the mag roller you can check continuity from the bias tag at the rear pcb, not easy to reach this tag.

otherwise strip down the back (flywheel / pcb bracket etc) and remove the boss holding shaft "B"

As a quick fix you could lub the shaft with wd40 or similar to free shaft B up, but may not last.

I'm in the car and headed to try out your idea as well as others (1 at a time...LOL).

Thanks for the pic!

Re: Ricoh 3030 with no toner in Type 1027 PCU...

In front of machine right now. I cleaned & sprayed a drop or 2 of wd40 on the pcu drive pin. I have tested 200 plus copies so far. The first copy of each run has a light band of dev. on the back side lead edge. That ends up touching the second copy contaminating it, but after that (98 copies) they look fine, feel fine. Do another run and exact same thing, first 2 have some dev. contamination. This a step forward as all were contaminated previously.

Any other ideas on the banding?
I probably will replace the pcu drive pin (correct name?) just to not get a recall on it.

Thanks everyone...I think I can see the light at the end of the tunnel.

Probably slight overtone causing the toner on the back lead edge. Is it dev (grit) or toner?
If dev you still may have still have poor bias letting the dev fall off the mag roller.
Any readings for vsp vsg vt?

Make sure its the dev drive you replace. Would probably clean up ok.

Hope it works out

Happy hols

The light band on the lead edge of the back side is coming from the transfer roller. Replace it the and they should go away.

But the transfer roller gets it from the drum which gets it from the dev unit, probably due to overtoning.
