Ricoh aficio 220 - replace photoconductor unit

Re: Ricoh aficio 220 - replace photoconductor unit

Hi all. So i decided to just clean the pcu and not change anything since the drum, pcr and gears looked fine. I rebuild it and when i put it in the machine, the warning message was gone but after about 30 sec it showed error code sc392. The drum is rotating, i checked. Anyway, after asking the customer a few questions about the machine, it seems like he tried to refill the toner bottle and after that the copier started to make black copies. The background is very dark but the original can be distinguished. I'm guessing it was the wrong toner for this machine. I am planning to make a few hundred copies with the top cover open to get rid of the bad toner but i need help in clearing the sc392 error. When the machine does it's initialization, the area around the pcu sounds fine so i'm guessing that i put correctly all the gears back into place. Any sp mode reset to this error maybe?

There is an old saying about jumping over a dollar to pick up a penny.

It would seem that truer words could not be spoken.
You came here for advice and completely ignored all of it.
You now have the drum coated in toner again, and it doesn't occur to you that the SC392 might (just might) be related to the situation?
On one hand, you're actually a bit lucky you didn't replace the PCU, because this problem would have returned due to your dumbass, cheapskate, client's stupidity, and lack of information he provided!
You had better dis-assemble and clean every single granule of toner out of the toner hopper and replace it with the proper type before you do anything with the PCU. Make sure to use the cheapest compatible brand you can find.He wouldn't want to waste his money on that OEM crap! Afterall, all toner is the same right?
The Dev is shot and in all likelihood will never come back, but if you can clear the code, go ahead and run your copies, but since it recycles the toner, good luck with that.
Maybe you could waste a little more time and replace ONLY the developer and see how it works.
Here:

S C 392 TD sensor initial setting error	change PCU unit
S C 392 TD sensor initial setting error	Drum does not turn
S C 392 TD sensor initial setting error	I D sensor defective or disconnected
S C 392 TD sensor initial setting error	poor connection of the PCU

I'm done with this topic!

This PCU was not desighned to be rebuilt as it is a supply item.

Hypothetical question :
What is the difference between 220, 1022 PCU and 1015, 2016 .... PCU
Except that the latter have all parts of the PCU, and the beginning of the series dont have .

I should have listened to you all. Now i wasted my time and energy and in the end i still must purchase a new pcu unit. I couldn't hold my curiosity to see how the pcu unit looked like.

Well.... This thread has definitely brightened up my Monday morning .

If someone tells you not to step into a fire coz it's gonna burn, would you not listen to them?
The best way is to learn from mistakes, we've all made them. So learn from our experience......

Re: Ricoh aficio 220 - replace photoconductor unit

Hi guys. So i can't get rid of this machine. It makes dog ears when it exits the fuser and the paper like accordeon. I noticed that the paper reaches the fuser a bit inclined to the right,so that the right corner of the paper reaches the fuser first before the left one. What do you think could cause this? Someone told me it could be the registration clutch, others said that the registration bushings can cause this. I would really like your input on this matter. THanks.

Registration bushings.

I'm thinking that you broke off some of the entrance guide 'fingers' when you worked on the fuser.

The other possibility for the accordion jams is that one of the plastic bearing retainer bars in the lower housing is broken / gone. The heat roller is a tight fit, and if forced, the bearings will break the housing. Then the bearing and roller run off center, fall out of the support, and can even short the lamp to ground on the frame.

If this is the issue, so long as the heat tube hasn't been damaged, you can still use the fuser without replacing the frame. Remove the heat tube bearings and replace them with a set of bearings from the 35/45 series machines. The main difference is that the 35/45 bearings have an additional shoulder on them. You can use this shoulder to rest against the metal frame of the bottom unit, but you will have to make sure it is flush on both ends otherwise it will be a very tight fit.

Good luck with the old dog. I actually still have one of these out in the field that I'll be seeing late this week or early next week so I can feel your pain!

You're right. I checked the machine again earlier this morning and this was it.I can't figure out how i could not see it. The last finger on the right was broken. That explains why it always made dog ears only on the right side, never the left side of the copy. Problem solved. Thanks a lot guys. There were many great and usefull posts on this one. I owe you one.
