Troubleshooting 3-17
Figure 3-1 shows what a printhead faceplate will look like after a
good cap/wipe/purge blade wipe. Notice that there are no smudges or
streaks of ink in the nozzle area.

Figure 3-2 shows a close-up of the printhead faceplate identifying the
tiny drops of ink that indicate a cap/wipe/purge gasket leak. Notice
the “V” or funnel shape the droplets form just under the area where
the cap/wipe/purge gasket seals against the faceplate (ink stain).
Random drops can be ignored.

Figure 3-3 shows the affect on the printhead when the cap/wipe/purge
blade is not working . In this example, the blade has several (6)
defects. In most cases, you will probably only see one smudge or
streak.
