PRIME Plot
Before printing and at regular intervals during printing, the plotter wipes
the ink cartridge jets at the Service Station. The ink cartridge jets can
still become clogged, however, especially with prolonged exposure to
the air or with disuse.
Use the PRIME function to clear the jets and to check that the ink
cartridges fire properly. We recommend that you prime the Cartridges
when they have not been used for a few days to ensure the best
possible print quality.
When you press PRIME, a test pattern is printed. The test pattern
consists of one wide band of black, three thin bands of each color from
the Tri-Color Cartridge, and a series of segmented sloping lines. Each
segment in the sloping lines represents one jet.
The bands should be smooth without dark streaks or white lines. The
sloping (diagonal) lines should not look fuzzy or contain gaps. If you
see discrepancies in the pattern, prime the Cartridges several more
times. If you still see discrepancies after priming the plotter several
times, you should clean the Cartridges. See Chapter 3, Section 6.2 for
cleaning procedures.
If you suspect that an ink cartridge has become clogged during
printing, press PRIME.
The Cartridges will fire into the Service
Station, which will purge the jets.
Printing will resume after this
purging.
