PLEASE HELP. Ricoh 161

[tham1010]

Hi guys,
Please help me. I have a big problem. I have Ricoh Mp 161. The problem is that the images comes out gray and weak. The images quality is poor. As a result to this poor quality, I changed the following parts into the PCU.

1- the drum + the blade
2- the Developer powder ( type 28 original)
3- the developer gears.

I did developer initialization once I changed the developer at first I got error C392. Then after few tries I could do developer initialization. The first couple of pages came out with very poor quality. I did Toner supply order but this didn't solve the problem. When I add some toner into the developer tank manually, the images comes out with very good quality till the toner quantity finishes. I have doubts about the TD sensor

I used another new CPU and it worked fine. I can say they the machine doesn't ask for toner for a reason I don't know. I put 170 grams of Developer powder. Wasn't this enough? I searched a lot and no one could tell me how much developer had to put so I put 170 grams.

Could any one help me stop the automatic of TD sensor so I can let the machine use specific manual values hopefully I would find out if the TD sensor is the problem. I need help guys. I have been searching for few days.

thanks

where did you get the dev powder is it OEM?
Are you a Ricoh tech getting OEM supplies?
Do you have the service manual? (guess not since you said "Could any one help me stop the automatic of TD sensor ")
Did you check to make sure the TD sensor was operational?
frankly using Non-OEM parts and supplies will bite you in the buns.

Re: PLEASE HELP. Ricoh 161

I think the problem is because you are using a non-original developer (chinese), they come without toner just the iron material, (the SC error code makes me think this),
Now when you added toner manually it worked fine, but as soon as this toner was used (depleted) the machine didn't replace it (didn't turn the toner bottle) because you initialized a "raw" developer (a chinese developer without toner in it), now this is what you can try: add some toner manually to the developer, run a few copies until you get a good quality (3 or 4 copies), the RUN the initialization at this point once again, the machine will"memorize" this toner/developer ratio and will mantain it.

Now on the grams, Just check the developer material slightly covers the DV unit agitators, -or a little less-. (I never weight "the grams", just by seeing it I know is correct, (or not), experience I think).
Try that,

If still in problems,

Nice diags.
I thought the same about China dev and lack of adding toner to the mix b4 adjusting.. I never used that crap.. too many headaches involved.. i think this user has come to realize those points.

Why have you started a brand new thread about your on going saga?

In your original thread you talk about buying a non original drum unit that apparently works 'well enough', and also looking for advice about parts/developer to rebuild the other one. What happened?
You also talk about the expense to buy new (original) parts in your country. I have no idea how much you're talking about, but I feel like the amount of time and money you've wasted thus far probably would have been better spent buying an original PCU and your problem would have been resolved weeks ago, and for a very long time.
Good night....

1- I bought this dev powder from a local shop here in Egypt. %99 of the parts aren't OEM but Chinese parts with different quality. I supposed the dev powder is high quality powder because i checked the lot no as well the serial number and i found the same dev package on many well known web sites. "Made in Japan" is printed on the package. It was the most expensive powder in the shop. I will enclose a photo of the powder bag.

2- Yes, I have the service manual and checked how to stop the td sensor but i read that I have to put some settings manually to make the machine works fine. I have had this machine since 2014 and I saw all the videos on youtube and read everything about this machine. but I still need some support and guide to do something for the first time.

3- I know using non- OEM is harmful but here in Egypt No one use original parts. They are so expensive so most of the merchants import only Chinese copies. 70680985_2803103596646135_8678843103676727296_n.jpg

Thank you for kind reply. I appreciate it.

1- I don't know if the dev powder is original or not but it was the most expensive powder in the shop and " Made in Japan" was printed on the bag. I checked the Lot no and saw the same bag on many famous website so I assumed it was a high quality powder. I don't know if the powder is with toner or not I tried many times doing developer initialization but I got error messages so I checked the tank gears again then put the PCU again and that time I could do developer initialization while the toner bottle was inside the machine. I did 2 copies but the quality was too poor. I did toner supply order and tried 2 copies but it was the same poor quality. I opened the PCU for the third time and there very little toner in the side part of the machine.

2- I think I didn't put enough dev powder because the developer just cover half of agitators or even less. I didn't want to put much so I would leave a space to the toner. What would happen if I add to much toner? Would this be harmful?


I will enclose a photo of the first copy after replacing the developer. I will enclose the dev bag hopefully you can read the content of the bag. I don't know if it is raw or not.

In Egypt people are so poor. They use only cheap Chinese parts. Some of them are very bad and some of them are acceptable. I bought the developer powder for about 15 american dollars ( a bag or type 28 - 354 grams).

I know the original parts are better but they are so expensive for me. The machine itself is used. Most of the people buy these imported used machines after working in Europe for years. The counter of my machine was 140,000 copies when I bought them. Now it is 214,000 copies.

I am so sorry for starting a new thread. I didn't know i had to complete on the old thread.
Yes, in my country it is expensive to buy original parts. %99 of the parts are Chinese from Alibaba. com I bought the developer page for about $15 and the new PCU for about $80. The developer grears are for about $3 and the drum+ the blade is for something around $ 8. This is what we can endure. All these parts wouldn't last long and we know that so we make changes every few months in the PCU

Re: PLEASE HELP. Ricoh 161

usually when I recondition a drum unit in the developer (only original) I never add toner because it is already present in the right quantity, I check the sponge seals inside the drum unit that are not damaged. toner hopper must be well cleaned, I usually replace the slider ass'y (code G0203334), I clean the inside of the machine well (red led bar, rarely the laser ,etc.).

It better to use genuin drum unit not only because of developer etc but after few copies gears warn and even if you replace them developer cover then and destroys them again.
I don't know if there are relaible compatible and cheaper drum units . For example for af 2022 there are no relaible compatible drum units.

Re: PLEASE HELP. Ricoh 161

There are compatible pcu for mp161, 2027 and other color models, they cost almost half of the original and make half the pages

Re: PLEASE HELP. Ricoh 161

i use china supplies for my MP161 . they work fine. It could be he use all the developer powder in unit which it can not do that, would cause it to lock up.

Re: PLEASE HELP. Ricoh 161

just buy a pcu type 1515 saves lots of time and in the end money
