Excuse me, I thought that I have translated my writing in English. I did not notice it because I see whole website translated to German. You answered anyway, thank you ...
From you sent link I have already and there is unfortunately nothing about sc29500 in it. I do not believe this error code for consumers. Technical service is not profitable, that means my Ricoh ends up in garbage.
In any case, I would like to try to send my previous font again in English for those who could not understand.
"Hello, thanks for the answer. I wanted to know if I can fix it myself because service providers may be more expensive than machines. I also looked in the manual but could not find anything. Could you tell me where to find it in the manual. thanks again in advance .. "
Maybe I will eventually hear about sc29500 .. (Google translator

Moin tagoz,
Deutschland ist ein große Land , wo bist du?

Good morning, Germany is a big country, where are you? If you are near me, maybe I can help. I work next to a Ricoh dealer and they gave me the answer to the Fehlercode 29500.

Hello Earl Smith,
I live in Berlin. That's very nice, thank you. That's what you said that sc29500 "there is an air trip error (error at the vent detection switch or error at the air outlet lever)" hot. I should know where these switches or levers fit so that I can test. The printhead I once removed vent hose is free but in the environment no switch or lever seen.

This is the error code explanation from the Service Manual ...
Exactly as Earl posted previously.

I thank you webtrekker .. Unfortunately, I do not know where these switches sit and how it looks .. Honestly I could not check whether a switch works properly. At the most see if it fits properly ..

I can't find anything in the Parts Catalogue relating to 'air purge' or 'air release.' Maybe it refers to the minute bubbles in the ink when head cleaning and recommends you turn off fror a while to let the bubbles settle. Or maybe it's overheating due to the right-hand side vent being blocked.

The only reference I can find to a 'lever' or a 'valve' of any description is the part J0254525 as seen in these two diagrams, but don't know whether that has anything to do with it.

webtrekker, thank you very much. Jo254525 unfortunately upper cover switch. It should be somewhere near the printhead I think .. Nevertheless, I appreciate your efforts. Thank you so much.

To be honest , most of the parts inside these printers are made of plastic and the moment you start to try and dismantle the things , something will break. The printer shop wont try any more and replace the printer under guarantee. But only if you bought from them, naturally.

Webtrekker I thank you a lot, problem was switch J0254525 .. Although it is exactly the same switch as the top cover lid but of the switch even a seat behind the print head when the stand was in peace and to the switch hangs a lever to operate the switch. Lever had slipped out .. I have locked the lever, error is gone .. Now I have error code sc 28111 , this is a printer. Although I have no guarantee but actually unpacked completely new.
