Abstract
According to examples, an apparatus may include a processor and a memory on which are stored computer-readable instructions that, when executed by the processor, may cause the processor to access a characteristic of a motor coupled to a carriage in a printer. In this regard, an ink cartridge may be mounted on the carriage and the characteristic may be of the motor during movement by the motor of the carriage. The processor may calculate an amount of ink in the ink cartridge based on the characteristic of the motor and may determine whether the calculated amount of ink differs from an estimated amount of ink in the ink cartridge. In some examples, based on the amount of ink in the ink cartridge differing from the estimated amount of ink in the ink cartridge, the processor may disable the printer and/or generate a notification.
