the print heads left far enough so the vacuumed print head brushes past the wiper. The wiper cleans the
ink from the print head.
Next, the carriage moves the print heads back to the home position. The maintenance unit caps the print
heads. A cam on the main shaft below vibrates the small scraper. This removes the ink bolus from the wall
of the trap and sends it to the ink collector tank.
• This cycle is repeated for each print head selected for cleaning. For more, see Section "4.
Troubleshooting".
• This cleaning cycle is also done automatically for all print heads if the printer stays idle for the time
intervals shown in the table below.
