First writing line of a page at the developer

the wear strips in the tray, and replace if
they are worn.

Check the cable routing for the printhead
( p.263 "Printhead Service Check").

up.
Check that the narrow media flag rotates
freely and securely. If it is dislodged or
broken, then replace the rear exit guide
( p.103 "Rear Exit Guide Assembly
with Sensor and Reversing Solenoid
Removal").

Media more than 14 inches too long over
the manual feeder sensor. Possible causes
include multi-sheet feed or pre-staged media
