When i put on fax printer SP1000SF,it show printer error and fuser temp.

That error indicates that your fuser is not getting hot enough to fuse the toner to the paper. If you can get to it then make sure all the cable leading to the fuser are hooked up well. If they are and nothing has wiggled loose then the fuser is likely faulty and needs to be replaced.

After extracting the files and getting the error message that you OS is not supported, browse to the Companion Pro LL V2_0_4 folder and open the Companion folder. Double click setup, and only install the Printer and scanner drivers when prompted. The default location that the software is saved to is listed below...

oh its a big problem.fusing temperature error means that either the thermostat or thermister is open in fuser unit. only a Ricoh technician can check it and tell you as it requires a lot of stripping to take fuser unit out and test the thermostat. there is no reset procedure for it mate.

You need to have the Fuser replaced

You must have the FUSER replaced.

Sir,
this error usually ocurs when you towner is empty or have completed is age.But as you said error fuser temp this might be that you priner buffer has got damaged while it repaire able bus is expncive so I would rather suggested to buy new one printer and Canon and HP are the best brand in my dictionary so you can try one of them.

fuser is faulty,pls get replaced.

H4 in 161, fuser low temp.; instantly solve it by simulation (c-auto-c-auto) 14; check thermistor; check fuser lamp by 5-02. it is to blink!
