-Check that the media used for the calibration
is white.
-If the media used is too dark, try the calibration with white
media. If the error persists, replace Lens Cover Assembly (See Lens
Maintenance).
-If the Carriage positions itself directly over the black arrow,
try loading the media a few millimeters to the right or left of
the blue line on the Platen - this should be enough to prevent the
error. Alternatively, paint the black arrows with white correction
fluid or stick a white label on top of the arrows.
