Functional Checks of the Printer/Charger
Pressing the FEED and PRINT buttons simultaneously causes a
test pattern to print. See Figure 45 (on page D-54).
Test Pattern
The test pattern is used to confirm that the print head is functioning
properly. If any of the print head elements are not functioning, a white
line will appear vertically down the printout. A defect in the paper may
also cause white lines or light printing. Repeat the test pattern to confirm
any suspected printing problems. If paper advances but nothing prints
out, check to be sure the paper is inserted properly (see page C-48).
