 The machine executes the print head cleaning cycle with the carriage unit
positioned over the maintenance unit (1).
 The ink collector tank (2) collects the ink drawn from the print heads by the suction
pump inside the maintenance unit during the print head cleaning cycle.
 The ink collector chip (3) detects when the ink collector tank is installed correctly. It
will signal an error if the tank is not installed or not set correctly. Printing cannot be
done unless the tank is set correctly. This sensor also detects when the ink
collector tank is full.
 The right sump (4) resides behind the ink collector tank and directly below the
maintenance cleaning unit. This is an open sump that collects the ink that is wiped
and scraped from the print heads at the end of the cleaning cycle.
 During printing, the machine occasionally flushes ink through the print head
nozzles (with a very small amount of ink) which falls into the left ink sump (5). This
keeps the nozzles primed and in good working condition. This operation is
controlled by the machine firmware and is not part of the print head cleaning cycle.
