Included are embodiments for providing a service station routine. Some embodiments of a system include a service station for receiving a handheld jet dispensing apparatus and a memory component that stores logic. When the logic is executed by a processor, the logic may cause the system to, in response to the service station receiving the handheld jet dispensing apparatus, identify the handheld jet dispensing apparatus, where identifying the handheld jet dispensing apparatus includes determining a time of a previous maintenance to the handheld jet dispensing apparatus. In some embodiments, the logic causes the system to determine whether the time of the previous maintenance meets a predetermined threshold, in response to determining that the time of the previous maintenance meets a predetermined threshold, determine a desired maintenance routine to execute and execute the desired maintenance routine, and record a current time as the time of the previous maintenance.
