SPARCprinter Adjustments -- (aka "The Magic Screw Job")
=======================================================

When it gets to the point it's making BOLD HORIZONTAL lines and
the U2 error has appeared on the display panel the following
temporary fix may get you going again.

1)  Take off the lid to the Top Cover (the door on the top).
      a. It's got two phillips head screws.  One on the left
         side and one in the front.
      b. Open the cover slightly and remove the lid, exposing
         the top of the ROS.
      c. Close top cover.
2)  Locate and turn this silly little adjustment screw (frequency?)
      an eighth or a quarter turn counterclockwise.
3)  Either put the lid back on or hold down the button on the left
      side which lets the printer know that the top cover is closed.
4)  Print.

Top View w/ lid removed.
"S" marks the adjustment screw.
"B" marks the button that tells it the cover is
closed.

Don't tear up any good laser printers trying this, but if you've
got some that are doomed for the scrap pile (at $600 per printer
for repairs I s'pose that's likely) it's worth a shot.  

If this works for you and saves you $$, please send a token
sum to me in the form of a personal check or money order.
If it destroys your system and shuts down your business, call
someone else...I claim NO responsibility.     :)

later,
