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.

SOURCE: Ricoh Aficio 2238c: Fuser Oil Unit

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.

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.

ERROR CODE E-5 HELP RICOH 4522


If you press the "." key you will get the last 2 digits to complete the error message. For example: "E542".
Whatever the result, 'E5xx' is always related to a fuser error; That means, you have a blown fuse, lamp, or thermistor, and the problem, and the service code can only be reset by a technician in service mode after the fault is fixed.

Ricoh aficio 1018d sc 544


Hello!
This code is related to a Fusing low temperature error.
You probably need to change Hot roller (or fusing rooler) and thermistors.
You can reset this code but it will pop-up again sooner or later.
The best advise i can give you is to call a technician (if you do njot have technical knowledge)
If you still want to reset the code tey this:
Press yellow key
Press in the key pad 107
Press red key at least 5 sec.
Exit all the way out.
Turn the machine off and on.

Hope this helps you

This is a software performance error; However it is most often caused by a deteriorating drum unit. There is no exact solution, but 9 times out of 10, a new drum unit, and fresh developer will solve it.
Outside of that, it is likely a board problem -possibly BICU
