Eroare Copiator

Copiatorul meu, Minolta EP 4050, a intrat in greva. Apare pe ecran codul de eroare C0200. Am cautat pe internet si am gasit urmatoarele:
"CO200
Yes ladies and gentleman, I have a PERMANENT fix for your 200 codes. Take the corona advance motor and throw it away, YES throw it away! In fact, throw away that stupid photosensor and those pain in the ass cables. After throwing away all the junk that should have never been put on the main charge to begin with, pick up the phone and order the "fixed corona" modification. That right now you to can spend more time doing other things, like cleaning the machine or replacing those crap teflon rollers.
part #
3050-1135-0099-01
4050-1134-0099-01
These are the part numbers for the fixed corona E-PROMS. They should also include the new fixed corona hardware. That's right, it uses a single piece of corona wire instead of the spool that we have all come to "love".
EP- 4050
C200
First unplug the main charge corona take up motor as it may break the corona wire. next the wire is very thin and tends to oscilate out of control and cause the C0200 code. If a new wire spool, or grid doesn't alleviate this problem simply use electrical tape on the inside housing of the main charge corona assembly.
C200
There is a new part # for the charge corona. The old style has a problem with the wire cutting the block and breaking. The new ones have a brass post to prevent this. part# 1139-0313-01."

Despre ce este vorba ? Nu inteleg ce este acel CORONA !

Copiatoarele ce folosesc toner au nevoie ca acest toner sa adere la hartie.
In acest scop se genereaza o tensiune electrostatica de valoare mare 5-10Kv, care se aplica printr-un fir subtire de material dur, de exemplu wolfram, pentru a se electriza hartia.
Sunt mai multe tensiuni care se genereaza fiecare cu un anumit rol in procesul de printare.
Practic  acest fir este intins intre doi suporti izolatori si se afla undeva pe traseul de incarcare al hartiei.
La tine sau acesta este rupt sau scade tensiunea respectiva  ca urmare a unui scurtcircuit sau proasta izolatie a firelor.

Si un exemplu aici:

Multumesc pentru tot MISTER_RF! Mi-au fost de mare folos raspunsurile tale. Astazi ma apuc de cautat firul CORONA, poate rezolv problema singur fara sa chem "specialistii" care vor 100lei/ora ...
