Replace the touch screen. It's a common fault on this model. B223 9900.

You need to replace the touchscreen, there is a known manufacturing defect that Ricoh is addressing by supplying updated ones to direct offices and dealers gratis. It's getting kinda late in the game to get them though, check your local office. Search the forums for this extensively queried subject (needs a sticky!).

But that'd just be easy, wouldn't it?

How do you manage to do the touchscreen adjustment? .

Clear Modes, 1, 9, 9, 3, Clear Stop x5. Screen adjust is #1, touch with a pointy but not sharp instrument on the circles as prompted and exit.

reset copy sp 7804 and the pcu's u replace

No, if you just reset the PM counter the machine won't set up the new PCU's or developers. Go into SP3902, which is Manual New Unit Set. Tell the machine which parts you are replacing and it will initialise them when you turn it back on.
