Ricoh mpc 2000 - SC553

[kalaris]

hi
Someone who has really solved the problem sc553 without necessarily having to replace the unit full merger?
I saw where the post is not about problem solved.
thanks

It says the heating roller reached more than 230c for 1 sec, so the software makes this error.

Try updating the firmware, clean the thermistors, and adjust the power timings, and check that no one adjusted the temperature above standards in the SP settings.

It can also be the heating lamp that has internal shorts in the "glowing wire", so it's too hot. It's a lamp, just like when you kick a bulb, it lights stronger just before it dies...

I could think of a problem of some component of the unit fusion, whereas the same installed it on another copier and I created the same problem at power. The thermistors are new.

Replace the orange foam roller it can become worn and allow the belt to slip

Also, see what the customer is running. If they are running super long jobs with thicker or 11x17 sheets, probably over 100, that could be your problem too. These smaller machines aren't made to keep up with that sort of demand.

Also, Turn fusing idling on.

Also, if the machine is by a cold air output (Air Conditioning vent) or next to a door where cold air comes in, I have seen this cause this issue as well.

Hey looks like your on to something there, just open up the fuser unit and test the components inside, sounds like maybe a thermoswitch is open.

Re: Ricoh mpc 2000 - SC553

I remember that the Thermistor sensor on the pressure rollers, use to sepperate from the metal lip that is touching the roller, causing it to measure wrong temperatures, check if that has happened.

This fuser is very much like the fuser in MPC3300 units. A SC553 typically meant one of the dual lamps for the heat roller was open or perhaps a thermofuse popped. I would give those a check.

Re: Ricoh mpc 2000 - SC553

Consider that I opened the fuser unit tested components, replaced: thermopile, thermistor and tested lamps and thermostats. I have two copiers from clients with the same problem.

I think the problem of the power supply

Check out the fuser connectors, on the fusing unit and in the machine

We have the same error code again with the second unit. In both fuserunits, the (recently new) transfer band was wrinkled (the new after 2500 A3) on one side and run out of the lead. after a provisional smoothing of the belt and bringing it back into the lead, the error code is gone for the time being. How can the crumpling of the belt be ruled out.

Wish you all a peaceful and healthy new year!

Re: Ricoh mpc 2000 - SC553

Fully rebuild the fuser, rollers, belt, bearings or update the machine.

Re: Ricoh mpc 2000 - SC553

update the machine.

You mean an other one? ... and from an other brand - if?
It's too much maintenance after 200.000 prints to keep them running.
For us as a sustainable company that is certainly deficient. Also digital printers in this price segment should run and the wear parts must be counted on one hand.

Our fault: all can only press buttons on small cheap plastic boxes. Nobody learns anymore how to properly earn money with the right conventional machines.
So always nice every 2 instead of 20 years to buy a new one. And not only annoy yourself offline but also share the pain online in our huge suffering community.

Btw. If I know one thing as a media technologist, then this statement applies to all digital crunches. For every printed product there exists or existed a better conventional machine made of steel in which never all processes are digitized.

Machine is over 10 years old, how old is your computer?
