When you open the whole duplex unit you will see a very small metal tab with a screw, on the top right side on the machine. This activates the switch on the duplex unit.
Or with the duplex unit open you will se a small rectangle hole inside a switch, put a piece of paper or something to activate it, might got stuck.
This problem is very common on this machines.

There is a metal tab on the duplex unit that could be bent blocking the sensor. Once it is straightened out it should work.

How do i remove the paper from the duplex unit when there is no paper there

You could have a broken actuator or the spring came of. I would check all areas for paper not only the duplex area. I've seen paper jams in other areas show a different indication on the display.

MY Ricoh Aficio 2550 Printer I use it via IP in windows 7 and can't print Duplex Unit it said. Duplex :(Something conflict I can't Remember) Duplex: Unit not install

In Windows 7, you can right click on the printer under Devices and Printers, then select "Printer properties" (not "Properties"), then under "Device Settings" you can set the "Duplex Unit" to "Installed". Afterwards, you can go back to "Printing Preferences"->"Finishing"->"Print on Both Sides"->Print on Long/Short Edge.

How to install Duplex mode on PC for Ricoh aficio 2027

If you go into the print driver settings (Control Panel > Printers & Faxes > right click on the Ricoh 2027 and select Properties) there is a list of the available accessories under one of the tabs (I think it's either Accessories, Advanced, or something similar). Depending on the specific driver you have, you can either check the option for the duplex unit and then click Apply, or you can click the Update Now button to have the software itself check to see which options are installed on the copier.

Either way, you should be able to print duplex copies once you've done of those two things (assuming you actually have a duplex unit installed on the copier, of course).

How do we get this machine (ricoh aficio MP 2000) to duplex print?

There are certain models that can duplex and certain models that can't. Generally if a Ricoh copier can duplex it has a D after the name (like 2018D). If there is no option for duplexing on the screen or the ops panel, that model doesn't support duplexing.

Ricoh AP410 Duplex Error

it is possible that the duplex door switch or actuator is bent or out of position and not making good contact the switch on that model is a small plastic switch and it may need to be replaced if that is the case you may need to call a ricoh service tech to replace the switch.
the switch is inexpensive a few dollars but the cost of the csr could be $113.00 per hr or more.

good luck!

Back to back not working

Do you mean your duplex unit is not working on the right side of copier?If so, check your door interlock switch where the duplex unit closes up against the copier.If it is bent or not making contact the oper. panel will not let you select duplex.

Operation of Duplex through computers

Go to "start" then "printers and faxes" ( If XP). RIGHT click on your default printer ( Ricoh 2022) select properties, at the top of the screen you will see a tab that says Accesaries" hilight that tab and down on the page that says "duplex" place a check mark where it says duplex. CLICK APPLY or it will not change when you exit.

hope this helps.
