Abstract

An adaptive wiping method of cleaning an inkjet printhead in an inkjet printing mechanism cleans two or more diverse printheads that have different wiping needs, such as those dispensing different types of ink. Each printhead has an associated wiper that is mounted on a single service station sled for relative movement with respect to the printheads to achieve wiping contact. By offsetting the wipers, during one portion of the wiping stroke, at least one of the printheads may be wiped while at least one other printhead is not being wiped. This adaptive wiping system allows the printheads to be individually wiped at different speeds, which allows the system to be tailored to meet the diverse servicing needs of different inkjet cartridges, for instance, those containing different ink formulations.
