Figure 4-4. Longself-test
Since the self-test prints across the full width of the carriage, it is recom-
mended that the printer is loaded with the widest paper possible to avoid
damage to the print head and/or platen. In addition, the total number of lines
printed is considerable, more than can be accommodated on a single sheet,
so fanfold paper is recommended for this test.
