From the manufacturer's web-site:

http://www.ricoh-usa.com/downloads/manuals.asp?tsn=Ricoh-USA

select your specific model of all-in-one printers, and download.

Try www.smpcshop.com they have many service manuals for usually $19.95.

Remove the ink collector from the back. If full, install new one. If it's not full check the contact (it looks like a phone jack) itmust be clean. Look inside the machine to if if the mating connector is dirty.

After you replace the ink collector there is a counter you have to reset it to tell the printer that you are inserting a new collector

You can find the driver on the Ricoh site. here is the link:

100% agreed with rrrdddrrrddd. In addition:
Go to Menu->System->INK CU Replace. You will get a warning that overflow may occur(and it's really a messy job), reset the counter and everything should be OK.

make sure printer is off. Then old down escape and online button at the same time. Continue to hold these two buttons down then turn on printer. Continue to hold those two buttons down (will take about 2 - 3 minutes). This should clear that message - worked for me!!!
