My old R200 is still ticki

My old R200 is still ticking. I have printed thousands of DVDs with it, but it has the common problem of having to nudge the tray. The clear tabs at the edge of the tray got messed up early on, so I cut them off. There is a sensor located somewhere under the left bottom of the ink cartridge assembly that may mess up the process. I cleaned it once, that seems to be the fix. I’ll see if I can find that link from a year or so ago.

OK, here it is! http://www.fixyourownprinter.com/forums/inkjet/27268
