MP5000

Anyone who have a solution fixing a problem with faint copies on MP5000?

Re: MP5000

Clean the optics and laser slit glass. If internal prints are also faint, check the developer and if the machine has the old style toner.

Second on the slit glass and optics

I also have noticed a few times even when the prints are still ok, but copies are washed out that doing a PM on the pcu with new dev will fix it. I had one i was stumped why the prints looked great but copies looked like crap and replacing the dev fixed it. check your pm count if your close or over I would just pm it. If it was recently PM with dev and copies look good then I would probably follow the advice on the optics.

The mag roller still get's coated with melted toner on these machines and the dev/toner ratio is usually quite weak from the start - no way to get proper blacks even if you add toner via SP and re-initialize the TD/ID sensors, somehow the process control restores it's weak solid. On the other hand it'S not really recommendable forcing too much toner since the DV unit would spill more toner as usual^^

If the PM counter is >120k your drum/opc might also start weaken the density. Dev target is 320k but if the customer is more of the quality demaning kind I'd replace it if I need to pm the PCU (120-160k).

I'm not really happy with these machines but it's just another bad chapter of a long history starting with the aficio 450 (toner crapper) then aficio 1045 (quite OK with no serious toner issues) then A2045 (another crapper) then A3035 (quite OK, sort of a "A2045 including all modifications" + better controller) then MP4500 (new toner - new issues, average machine) then MP5000 (no need to comment)

The core engine hasn't changed a lot since the A450 - same goes for the ongoing quality issues shared by most of the generations. Ricoh's printer engineers did a better decision sticking with the Type18 Dev/Aficio1045 Toner for the SPxxxx printer series up to SP8100. I actually had no serious issies with these printers while the ongoing re-invention of the toner for the copiers is always driving me insane. I also hate the toner recycling philosophy and I don't know how that should help the economy if I need to replace the dev way before the PM yield because there's too much paper dust inside. Especially picky customers does generate a lot of calls, complaining about some spots.

I'D like to see a B/W engine that is based of the MPC series - just with one PCU but also with a transfer belt to avoid direct opc<>paper contact and a good old waste toner bottle of course.

Me too, but I dont see it happening. They seem to be stuck in a grove on this design.

Well - they've improved the fuser a lot, even if it's a bit of an ungrateful job to maintain it. At least the oil-web seems to improve the lifetime of the fuser rollers a lot so there's usually no need to replace them until the press roller is worn out. I have machines with >500k counter out there that still runs with the first hot/press roller. Once I had no oil-web in my car so I tried to rewind the old one - some time later a workmate had to PM the machine and he told me that even this worked fine. All in all Ricoh did a good job with the new fuser design so they probably make it worse for the "whatever-is-coming-up-next-generation"

Re: MP5000

I second the issue of the brown coating on the mag roller - but that usually causes scatter right?

Is the drum original? We found the using Katun drums in these causes the copies to run light - changing dev made little improvement. We went back to the Ricoh drum and all was well.

Lesson learnt - stay away from "compatible" on this machine! The same happened on the MP4000 series.
