Eric,
After replacing the wiper via the above method. Do you do anything to reset out of the service mode,if you know? Will everything just go back into place on its own?
Good question Dan. Here's the rest of the wiper cleaner assembly replacement procedure:
*NOTE: YOU DO NOT HAVE TO TAKE YOUR MACHINE APART IN ORDER TO CHANGE YOUR WIPER CLEANER ASSEMBLY. The procedure is simple, I suggest (this marks my first official suggestion on Luminous Landscape) that EVERYONE with an Epson 79/9900 forces themselves to get comfortable with this procedure.
6. Turn the printer ON in the Serviceman Mode. (Turn the power ON while pressing [Menu-right arrow], [PaperFeed-down arrow], and [OK] button.)
7. Select SELF TESTING → Maintenance → Wiper Exchange → Sequence.
8. Press the [OK] button.
The Carriage Unit moves, then the Wiper Cleaner Assy moves to the replacement position.
DISASSEMBLING PROCEDURE:
CAUTION - The following procedure is performed with the power ON. Therefore, do not touch any other part specified in the procedure or press a wrong button on the Control Panel. If the [OK] button on the Control Panel is pressed, the Carriage Unit returns to the home position, so be careful.
1 - Push up the tab of the Wiper Cleaner Assy, and remove the Wiper Cleaner Assy.
ADJUSTMENT REQUIRED:
Be sure to refer to Chapter 5 “Adjustment” (see p252) and perform specified adjustments after replacing the Wiper Cleaner Assy.

1 - Counter Clear (Wiper Cleaner Assy)
*Note: from what I gather this is not a physical adjustment. This is simply a "reset" of the printer's log on your wiper's life cycle. According to the Adjustment Items chart, the Epson 79/9900 printers log the usage life of an amazing number of it's replaceable parts - all of which apparently are accessible/resettable in the "Adjustment Item" menu. When you replace the wiper cleaner assembly, reset the log. If you fail to do this nothing bad will happen, just the printer's log of your wiper cleaner assembly will be inaccurate.
