ABSTRACT:
An inkjet printing mechanism has multiple inkjet printheads which controllably eject multiple ink droplets, and has a carriage to carry the printhead. The carriage is designed to move the printhead through a print zone to a service station where the printhead is serviced. During a servicing mode of operation, the printheads eject ink droplets at the service station to clear the orifices of the nozzles of the printheads prior to printing. A reservoir is provided at the service station to collect the ink droplets ejected from the printheads during the servicing mode. Multiple chimneys receive ink from the multiple printheads and guide ink from different printheads to different areas of the reservoir. Precipitates that may form when different inks combine are kept away from the chimneys.
