[Misc] ricoh mp5001 fuser issue

[vga_man]

hello!
i've ricoh mp5001, which has a fuser problem after many copies
(13 landscape, 7 portial)
the copies becomes without fusing from the center and the attached picture describes that>
the problem with mp5000 and mp5001>
replaced upper roller and nothing changed :-(
any ideas please!?

What about the pressure roller or cleaning roller? Is there maybe toner on the fuser entrance scraping the toner off before fusing? Put the pressure roller on a flat surface to see if there's a gap in the middle. Try and jam the machine when the papers about to enter the fuser and see if the image is there. Has the cleaning Web been removed?

thanks a lot for your favor>>>
i've checked the pressure roller and changed the cleaning web too , nothing changed>>>
may increase fuser temp?

At pm counter 600k the fusing unit need a maintenance if fusing problems occur. What does the smc pm counter say?
Try a different paper format A3 or some such and printout a page with normal and then with thick 2 or 3 setting.
This happens only in the copier mode or copier and pc print?
With SP1-105 and 1-106 you have a look to the fix temp.

Thanks for replay!
Both print and copy mode with all sizes
Fuser counter is 130k..

I think you missed an important point here. When you print off heavy paper and the MFP is set to Plain paper, the temperature at the center of the fuser rollers diminishes gradually, and fuses poorly at the center. It's certainly possible that the fuser temperature has been altered. It's more likely though that your enduser is using media of 120gsm or heavier and has not selected the proper media type.

So you have four tasks:
1) Determine what weight paper is being used (and please don't tell me it's "Cardstock").
2) Determine what media type is set to the MFP tray.
3) Determine if the MFP is capable of of printing that media type.
4) And the hardest part: convincing your enduser that they must make a specific media type setting when they use that specific media type. Many endusers say: "... but I never had to set the media type on the old machine!!!" Well maybe you never did set the media type ... but maybe your should have been.

We have no detailed information at all about machine media and settings from the thread opener. Temperature drops only after many printouts. If the machine is not in the power-saving mode and in ready state, and when media 80g paper is inserted, then I would just test it with tray settings thick 2 or 3.
If the problem still exists, it is not the problem of paper/media (temperatur)and the machines/drivers settings, then the fusing unit has to be replaced.

Replace the lower pressure roller, that should fix the problem

Re: ricoh mp5001 fuser issue

The fact that vga_man has made no mention of media type tells me he has not given it due consideration. Any conversation about fusing must include details about media type and settings. =^..^=

Re: ricoh mp5001 fuser issue

Is just a personal speculation... the machine came out 2010 into the market. Fuser counter is 130k. If it's the first 130k of the fusing unit then he has round about 1.500 apv. The machine has been designed for 10.000 / 20.000 apv. We know what can happen if the machine stands more than as used.
3. and 4.pdf Could solve the temperature problem.

Re: ricoh mp5001 fuser issue

1. Check SP 1.106 thermistor center and end
2. Replace pressure roller
3. Change toner.

Re: ricoh mp5001 fuser issue

Thanks all for your favor.
Media type used: plain
Thickness: 70gsm
Fuser temp display: 150,160
May reducing speed by chance media type helps :-)

Re: ricoh mp5001 fuser issue

Replaced lamps and pressure roller..
Nothing changed.

[HitMan]

What about removing the Web as a test. It will still work without. Also how does the exit unit look? Any thing immediately before or after fusing could have an affect.
Also could look at the maintenance tab in user tools, if the papers a low GSM it may have to be set for type 1.
Are the thermistors contacting the heating roller correctly?

Re: ricoh mp5001 fuser issue

By reducing web motor speed seems that the problem gone

Thanks all :-)
