I have error sc301 in my copier ricoh aficio 4850 emf, I know that's error related to the fusing, But I do not know exactly where the problem is in the fuser.can anybody help PLEASE thank U
Has to do with the charging of your drum, its in the "cleaning assy of the drum unit
Most fuser problems have to do with the fuser lamp and or the thermistor, or the thermal fuse. If you can put you hand near, and I did say near, because the fuser is very hot and can burn you, you should feel heat. Use an inferred thermometer to pick up heat. Should be around 225 degrees F +- a few degrees. If no heat detected the lamp is bad or is not receiving voltage. The thermistor detects heat from the fuser roller, it lays on it, and sends a signal to the logic to turn up the voltage to the lamp or turn it down. The thermal fuse could be open hence not voltage to the lamp. Last but not least no power from power supply or no signal from logic board to turn up the juice. Hope that helps.

Error 990 can be cuased by many things. Most of the time it is related to the Hard Drive. you could try replacing it.

you really can not refill the bottle but I would recommend two things. One find a fuser oil unit on ebay and order it quickly. Next hit the yellow clear modes button, then hit the numbers 1 0 7 , then hold the red clear stop button till the display panel changes. hit copy sp, select 7 data log. now use the page down arrows located in the middle of the disply till you see 7804 push it then go to #10 oil supply and hit execute. this will reset the oil counter and allow you to use the machine till you get the new unit.

This is a fuser problem,possibly a dirty thermistor, but try resetting it first.....
Press yellow key
key in 1,0,7
then press and KEEP HELD DOWN the orange key until the screen alters into service mode. (about 5 seconds)
Then switch off the copier with the main orange on/off switch. Located just below the front cover....

In some models this
code means that the laser has aged and must be replaced.
But he would be interesting to know that model
is for being safe of this.
