Ricoh spc820dn problem developent unit.

[Killeromantic]

Hello I decided to clean the yellow developer unit because I had a vertical line. the problem is that with a brush clean up any residual toner and I think that could not be removed because now nothing is printed in yellow. that I can do to fix it.

The printer is a Ricoh SPC820DN, also'm looking model component or those which are compatible buy and own reserve.

First, developer units cause voids not lines. Charge rollers are usually your culprit. If the yellow pcu is not working at all now you have either not plugged it in, or really damaged it. Replace dev and/or drum.

Thank you know that developer units Ricoh support my SPC820DN, because I could not find that numbering is compatible with that printer. thanks for everything.

C4500 parts are compatible with your C820

But depending on the cost it might be cheaper to use the SPC color photoconductor kit(part#403116). I think you get all three drum units together in that kit. So, assuming that's correct----why pay almost the same price for just 1 MPC 4500 drum when for just a tiny bit more you can get 3? I think ebay regularly has those photo conductor kits at cheap prices.

Re: Ricoh spc820dn problem developent unit.

Thank you very much rose and blaze business, the problem that I present is that many times when printing on RICOH spc820 shows me one or two horizontally striped in yellow, I changed two yellow drum and for a while print well and then appears again problem, we made cleaning roller drum but the same improvement that nothing happens. finally disarm the developer unit and clean and discard any residual yellow powder to mount Dev seems to damage the unit because I think that dust could not bounce. So I wanted to buy only a DV unit. or try to identify the problem of the lines.

Seems to me that you've wasted a lot of money and only made the issue worse, if we revisit your post from a couple of weeks ago.

It was most likely a simple problem, that would have been quickly resolved with a single, routine service call
Cut your losses, and call a tech

sandmanmac the problem is that where I live there is a technical and much less room for Ricoh, all I have to order it to use and I have to be the technical and to defect the problem, I live in Cuba, thanks for your suggestion but unfortunately not an option for me.

I don't know how much this will help, but it could be that the toner or dust is interfering with the laser. If the laser's intensity is less due to dirt or toner, a machine will make light lines on the prints very similar to the ones shown in your picture.
Theoretically, there should be a blue tool inside the machine's front cover that you can use to clean the glass that seals the laser unit from that kind of contamination.

Iowatech thank you very much, but clean and probe several times with the blue tool that is on the front cover and everything remains the same. I could not even detect that cause yellow drum that line, I've cleaned all the yellow drum component.

I think you'd be best of hitting this thing with a FULL set of consumable items. PCU's, transfer unit, the works. If you get a machine of this size and capability, you can't skimp on fixing it. If it needs parts, fit them.

Re: Ricoh spc820dn problem developent unit.

if I have several stored supplies, the problem is that's happened to me twice with the yellow drum and almost always when they are halfway through their useful life.

Re: Ricoh spc820dn problem developent unit.

After looking at the photo you provided......you have a void (white line) on only the yellow portion being printed , if you cleaned the laser glass with the tool and the issue stayed the same-- With the white lines in your example pic......a new Y DV unit will probably cure the issue. The dv unit for that model is pretty inexpensive and the unit comes with developer.

Re: Ricoh spc820dn problem developent unit.

if that's what you will. I could find a complete drum yellow on ebay, for Ricoh spc820 sold only 3 colors and I have set as 3 of each color, and less yellow as two of the drum that story have the same stripe. Even I could not identify the cause of the white stripe in the yellow drum. as I have already changed to the OPC and remains unchanged.I would like to know the cause for tomorrow when I happen again. thanks for everything
