Funtional problem SC302

It depends on which Ricoh model.
Some Ricoh copier/printer use a corona wire for charging the drum, so SC302 means that the corona wire is ether broken or have some current leak. but in most case the wire is broken.
Other Ricoh copier/printer use a charge roller for drum charge, so on this model SC302 usually appear when the charge roller have a bad contact.

I have an Eror code of E061 on a Canon IR5020 what does that mean

A E061 error code is a drum potential problem. You mat have a broken Post corona wire or a broken Grid wire. The problem deals with the main chage corona unit. I would make sure that the unit is installed correctly and make sure none of the charge wires are broken.... It may be a bigger problem, I don't know what has been done... Good Luckl

The image does not transfer to the paper.

Sounds as though the primary corona wire is broken giving no charge to the drum, the developer clutch is not rotating the developing cylinder, or the transfer corona wire is broken.

The left side of my page is lighter than the right. The corona wire tab broke off - is this the issue - I need a new drum?


The problem you are having is caused by a dirty corona wire and if the tab is broken off then you have no way to clean the corona wire to restore dark copies. You will need to replace the drum unit in your printer. The part you need is DR360.

Brother not printing

Hi John, the machine keeps asking you to clean the corona wire because on start up or especialy when the machine readies it's self to start printing, it passes a voltage through the corona wire which helps the drum erase the charge on the organic photo compound the drum is covered in.
If the machine sees any problem with the transfer of this voltage it thinks there is a problem.
The corona wire can be cleaned by sliding the blue tab on the top of the drum from right to left a few times.
You should check to see if this wire is broken a very thin wire about the thickness of a human hair, if the wire is not broken then try cleaning the thin metal grid below the corona wire with a cotton bud , being carefull not to break the wire.
If this doesnt work then it sounds like the high voltage connection on the drum is faulty, and you will need to purchase a new drum ( or take it back to the supplier and say it is faulty and you want it replaced).
You ould also clean the surface of the drum itself carefully with a soft DRY clean cloth.
The only other cause is the high voltage supply pcb is faulty. Which if the machine is out of warranty is prohibitavely expensive to repair.

Hope this helps

Corona wires are used in the transfer/sep assy and drum charge. C0200 is code if they fault. To reset the machine open and close the front door, if ithe code comes back the corona wires and or assy need replacement

I have Ricoh Afisio Copier and I have error code SC301

That mean that you have problem with the charge corona, i'm not sure for which model do you talk about but it should be when you open the front door it has one black wheel, under the wheel has a black oblong(the corona) from which come out a wire which is connected near, so when you will locate that part(the corona) you will see that the part is attached to metal plate with one bolt under, so unscrew the bolt and pull the corona towards you but carefully and straight to not damage the drum when you will pull out the corona you will see that inside has two or one string wire, see do the wire is broken if is broken it will need to be replaced, if the wire is not broken you will see do the part(corona is dirty if it is , clean it up with clean cloth or if you have on hand put some pure alcohol 96% on the clothe and clean it up after that insert the part(corona) inside. you can't make mistake on the path where you need to return it has a rails on both sides if you do not set the corona on the rails it will do not enter, do not use to much force if do not want to enter try again. after you will place in it place don't forget to attach the connect the wire and screw the bolt. When you will do this turn the machine on again and see do will the SC 301 disappear, if do not disappear you will need to call service because some part need to be replaced.
Please rate the post if was helpful for you for i to know does this was helpful or not for to know to post some more information

Royal copier service code

Royal copiers are kind of old... But I believe that a C710 means that a charge corona wire is arching out or it could be broken. The fix I use to do is to clean the Primary & the Transfer corona wires carefully and pree the reset botton and see what happen. It could be a problem wit the HVTDC, but you may fix it with just cleaning the corona wires.. Good Luck
