Printing a Self Test

Running the p rinter's self test help s you d eterm ine w hether
the problem com es from the p rinter or the com pu ter:
If the self test results are satisfactory, the p rinter is w orking
p roperly and the problem is probably cau sed by you r
p rinter d river settings, app lication settings, com p uter, or
interface cable. (Be su re to use a shield ed interface cable.)
If the self test d oes not print prop erly, there is a problem
w ith the printer. See "Problem s and Solu tions" for p ossible
cau ses and solutions to the p roblem .
You can run the self test w ith either single sheets or continuous
paper. This section d escribes how to ru n the test w ith
single-sheet paper. See Chapter 3 for inform ation on load ing
and using continu ou s p ap er.
