mpc2000 printing demo page sometimes

mpc2000 sometimes will print a demo page overlapping the print or copy.Firmware upgrade?

Also lots of background/lines + drums look ok but am changing transfer belt cleaning unit which is definitely in bad shape. Frank/AP

Sounds like a board, RAM or HDD problem to me.

Only time I've seen this kind of thing was a hdd failing. Any SC860 range errors in the history?

on the copy quality side of problem print counter report see if it comes out clean if not then photo conductor assy might need to be replace also clean optics. Sounds like maintenance has not been done in a while. one more thing clean your laser shield glass too.

Usually simpler than that. Make sure the customer isn't being cheap and reloading once printed paper. I have seen similar complaints and in every case I can think of someone was reusing paper and either did a duplex job on it or loaded it wrong side up.

Just a thought so you don't go rebuilding an engine that won't run just because it ran out of gas...

Re: mpc2000 printing demo page sometimes

sorry for responding to your replies so late and thank you so much for your input. was at customer today and changed tb cleaning unit which was a significant improvement but drums will need to be replace though i innitially thought they were ok. A closer look shows they are causing some of the line that appeared
at the front side of machine.
Oddly, after changing tb cleaning unit a rubbing sound was made and the transfer belt at rear was damaged. The cleaning unit was installed carefully and correctly. There was also an sc441 code, I had to cut away a potion of tb at rear which was out of image area but which will need to be changed though it is printing and copying without incident. Did not see a test/demo page today. Will continue to post results until all is resolved. Thanks again. Frank

ps ----there are 58k black and 59k color totals on machine though the machine looks like a lot more was done.

I am a little surprised at the cost of color drum units. Are these prices for single color or are they sold in set. Also, are they including the developer part of unit? Do most techs rebuild these with drums + blades etc.? I will keep checking pricing and parts manual . Frank

Re: mpc2000 printing demo page sometimes

Officially Ricoh does not offer parts for the PCU or dev units except for developer itself. There are a few ways to go:

If the PCU is toast and the dev and dev units are completely shagged out you can get a complete PDCU for each colour individually.

If the dev unit is good you can replace just the PCU and developer material for each unit individually.

If both the dev unit and dev are still ok you can just replace the individual PCUs.

For the MFP the units are sold individually and are heinously expensive. There was a printer version of that engine where you got the colour PDCUs as a kit and black was seperate. The units IIRC were keyed / wired differently but could be adapted to the MFP and were cheaper.

I don't know if there are aftermarket kits to rebuild these but feedback I have seen here for newer units has not been great regarding the performance of aftermarket components.

Thank you Zed. I believe he just needs drum units. One place on ebay (vegadistributor) in Phoenix,Ar. selling for around $210 w shipping. Claims New modified oem drum units. I sent question regarding are drums oem + are units rebuilt etc.. They are selling 10 pack color units for $1392 ($139 ea). Frank

Re: mpc2000 printing demo page sometimes

I can't comment on what you might be getting. I work for the Ricoh mothership and as such I don't concern myself with trying to eke out cheaper solutions. Generally though, since OEM individual parts are not available directly from Ricoh you are likely getting aftermarket parts in an old OEM core.

Claims New modified oem drum units.

A couple things I have learned over the years.

1. Modified could be black drum unit modified to work in color position.
2. OEM does not mean Genuine Ricoh

Yes, I used OEM to mean Genuine Ricoh but you are right. The use of OEM may only refer to being made to the same specification as the original part.

We see this with our rebuilt fusers. The belt units and pressure rollers are clearly NOT genuine Ricoh but we are told the are OEM. I call BS there though because the rebuilds fail at an astonishing rate compared to new genuine Ricoh fusers so they must not meet the original specification.

As far as 'New Modified' that could mean damn near anything.

Either way the eBay source pricing sounds almost too good when compared to genuine Ricoh. I'd say just get a set for one machine and see how they perform before committing to any significant investment.

Can a black drum unit be used in place of a color by making some modification?
