Ricoh MPC 7500 J001 with no signs where to remove paper

Re: Ricoh MPC 7500 J001 with no signs where to remove paper

If jam D is a Fusing exit jam, the fusing exit sensor is failing. Whether it be a reed switch or optical sensor when they get old they tend to fail when they have been hot for a length of time. Once they cool down they start working for a while. The length of time they work slowly gets shorter. Common with optical sensors on older 35/45 ppm models and reed switches on older martini models.

i already changed the fusing sensor from another machine but the problem was same.. but i have since cleared the error by cleaning the paper trays with a blower. many thanks

You are on the right track, these boxes needs to be turned off for approximately 8 years to be reset...

aha aha sure but i love the print quality.. i have a xerox dc252 and i love the ricoh since its parts and toner are much cheaper compered to xerox

Re: Ricoh MPC 7500 J001 with no signs where to remove paper

thanks soo much for the reply.. yesterday i removed all the trays and used a blower on the machine then i went switched it off until today morning.. when i switched it on the paper jam error at D was gone but there is a new error sc555 which the manual says is a thermistor problem i used 5810 to clear it but it keeps coming back when i leave the machine idle without printing. i have put the machine on energy save mode and the error has not come back and printing is ok.. you have suggested ricoh mpc6502 or 8002. i will think about it since i have a very busy printshop and need a reliable printer, many thanks

Hi Timmytrinic.. i have a ricoh mpc6000 it shows paper jam at D and wont go.. when i switchoff the machine for like one hour the error goes and am able to print but whenever the error comes back it wont go until i let the machine to cool down for a while and try again, you had a problem like this and solved it b blowing with air but mine wont go even after blowing.. kindly help

Re: Ricoh MPC 7500 J001 with no signs where to remove paper

Hiya. Well found the problem and it was because of a combined help from the messages. I checked the draws and no paper stuck anywhere but as it was a power on jam as mentioned and as I had swapped the transport and fusee section it must of been a draw error...as someone had said. So I just air blasted all the area and sensors and it worked. There is or was alot of paper dust from cheap paper so if it happens again I will do a proper industrial blast and clean.

Hope this has helped anyone. Thanks for all your help. If I can help at all or any MPC Firmware as I have just had the latest which cured a scanner issue please ask.

Hi Teebee. Thanks for the advice. I will be putting back the boards today which I swapped to see if that was the issue and get straight on it before I continue with the main board.

I will let you know. Really appreciate it.

J001 is a 'power on' jam, you may have a flaked out sensor. I would suggest doing an Input Check to determine if any sensors exhibit paper present.

Had this as well,my fault was trapped wire caused by the controller board shorting out a wire-try -opening up the controller & then turning on-worth a shot!Did same as u ,unplug everything-draws open etc,good call on unplugging pf units

Re: Ricoh MPC 7500 J001 with no signs where to remove paper

Have you tried disconnecting / swapping the feed stations? Could be there's a sensor out in one of them. Also, take out the LCT and all paper trays before you start it up, may be a trapped wire.

Hiya....it does not have an LCT but I will try with all the draws open tomorrow. It's funny tho as it just does not show anything to say where any paper is. I have taken a picture of the display but not sure how to put it in here with my iphone but will do. I have replaced the paper trays supply board as well. Appreciate your time.

Hiya Besserwisser. I was thinking that as just took some main board connectors off to see if I have any change but no joy. I will have a go with a spare machine I have and let you know. Thanks for coming back so quickly.

Hiya

I have swapped the Power supply boards/unit, both, and still no good, always checking to see if the units I took off work on the donor machine and all fine with that. The last resort is now the Main Boards....if anyone has any other ideas that would be gratefully received

Hi
Had a simular problem last year and had to remove the power supply..strange, but it helped...try first with a used one....they are not cheap..
