Abstract
A method of operating an ink jet printer with an included printer controller, where the ink jet printer prints using a replaceable print head that includes a nozzle plate and an ink reservoir. The printer controller tracks a usage of ink from the ink reservoir and a number of completed nozzle plate wiping operations. The print controller determines, prior to initiating each nozzle plate wiping operation, whether to initiate an inter-layer spitting operation instead of the nozzle plate wiping operation. The printer controller initiates the determined one of the wiping operation and the spitting operation.
