Abstract
In some examples, the disclosure describes a printing device that includes a processor resource, and a non-transitory memory resource storing machine-readable instructions stored thereon that, when executed, cause the processor resource to: estimate a drying time of a print medium received at an output roller from a print zone, activate the output roller at a first speed to move the print medium to an output tray in response to receiving the print medium from the print zone, alter a direction of the output roller to move the print medium toward a turn roller at a second speed based on the drying time of the print medium, and stop the output roller to prevent the print medium from reaching the turn roller for a period of time based on the drying time.
Claims15
A printing device, comprising:
- a processor resource;
- and
- a non-transitory memory resource storing machine-readable instructions stored thereon that, when executed, cause the processor resource to:
- estimate a drying time of a print medium received at an output roller from a print zone;
- activate the output roller at a first speed to move the print medium to an output tray in response to receiving the print medium from the print zone;
- alter a direction of the output roller to move the print medium toward a turn roller at a second speed based on the drying time of the print medium;
- and
- stop the output roller to prevent the print medium from reaching the turn roller for a period of time based on the drying time.
A non-transitory memory resource storing machine-readable instructions stored thereon that, when executed, cause a processor of a computing device to:
- determine a quantity of time for drying a print medium based on a quantity of print substance deposited on the print medium;
- instruct an output roller to rotate in a first direction to move the print medium from a print path toward an output tray;
- instruct the output roller to stop before releasing the print medium into the output tray;
- instruct the output roller to rotate in a second direction to move the print medium to a duplex path;
- instruct the output roller to stop before the print medium reaches a turn roller of the duplex path;
- and
- instruct the output roller to rotate in the second direction when the quantity of time has passed.
A system, comprising:
- a print zone to deposit a print substance on a print medium;
- an output roller to move the print medium from the print zone to an output tray when rotating in a first direction and to move the print medium from the output tray to a turn roller within a duplex path when rotating in a second direction;
- and
- a controller to:
- determine a quantity of time to dry the print substance on the print medium based on a plurality of properties of the print substance and print medium;
- instruct the output roller to move the print medium at a first speed in the first direction such that the print medium passes a duplexer;
- instruct the output roller to move the print medium at a second speed in the second direction toward the duplex path such that the print medium stops before reaching the turn roller;
- instruct the output roller to move the print medium between the output tray and the turn roller for the determined quantity of time;
- and
- instruct the output roller to move the print medium to the turn roller.
