The print head is operatively connected to the supply of ink and ejects drops of ink to form an image. The cap is arranged to receive waste ink from the print head during maintenance operations. The waste tank is operatively connected to the cap for storing the waste ink. The control system is operatively connected to the print head for keeping an estimate of a volume of waste ink that has been discharged into the waste tank and adjusting the waste ink estimate to compensate for evaporation of the waste ink.</p> |
