Pick roller speeds

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: detect a slippage probability for a pick roller of a print medium to be utilized for a print job of the printing device, determine a speed of the pick roller based on the slippage probability, and instruct the pick roller to be activated at the speed to pick the print medium and move the print medium to a turn roller.

What is claimed is: 
     
         1 . A printing device, comprising:
 a processor; and   a non-transitory memory resource storing machine-readable instructions stored thereon that, when executed, cause the processor to:
 detect a slippage probability for a pick roller of a print medium to be utilized for a print job of the printing device; 
 determine a speed of the pick roller based on the slippage probability; and 
 instruct the pick roller to be activated at the speed to pick the print medium and move the print medium to a turn roller. 
   
     
     
         2 . The printing device of  claim 1 , wherein the slippage probability is based on a notification from a sensor that the print medium is a particular type of print medium. 
     
     
         3 . The printing device of  claim 1 , wherein the slippage probability is based on the pick roller exceeding a threshold distance compared to a distance traveled by the print medium. 
     
     
         4 . The printing device of  claim 1 , wherein the slippage probability is based on a detected drop in torque of the pick roller. 
     
     
         5 . The printing device of  claim 1 , wherein the slippage probability is based on a pick roller type of the pick roller and an indication of a selected type of print medium at the printing device. 
     
     
         6 . The printing device of  claim 1 , wherein the speed of the pick roller is initiated at a minimum speed when the slippage probability is above a threshold value. 
     
     
         7 . The printing device of  claim 1 , wherein the processor is to apply a braking to the pick roller when the pick roller exceeds a threshold distance compared to a distance traveled by the print medium. 
     
     
         8 . A non-transitory memory resource storing machine-readable instructions stored thereon that, when executed, cause a processor of a computing device to:
 instruct a pick roller to rotate at a first speed to pick a print medium to provide the print medium to a turn roller from a print media tray;   determine a slippage event of the pick roller based on a rotation of the pick roller and a distance traveled by the print media from the print media tray; and   instruct to pick roller to rotate at a second speed to pick the print medium to provide the print medium to the turn roller from the print media tray, wherein the second speed is slower than the first speed.   
     
     
         9 . The memory resource of  claim 8 , wherein the processor is to apply braking of the pick roller to alter a speed of the pick roller from the first speed to the second speed. 
     
     
         10 . The memory resource of  claim 8 , wherein the slippage event is determined based on a change in torque of the pick roller at the first speed. 
     
     
         11 . The memory resource of  claim 8 , wherein the slippage event is determined when the rotation of the pick roller exceeds a threshold distance for the distance traveled by the print media. 
     
     
         12 . A system, comprising:
 a media tray to store print media;   a pick roller coupled to a motor to interact with the print media within the media tray;   a turn roller to receive print media provided by the pick roller; and   a controller to;
 determine a type of print media within the media tray; 
 determine a speed to be utilized by the pick roller for the type of print media; 
 instruct the pick roller to rotate at the determined speed; 
 alter the speed of the pick roller in response to a detected slippage event to a lower speed; and 
 instruct the pick roller to deactivate when the print media travels a particular distance. 
   
     
     
         13 . The system of  claim 12 , wherein the motor is utilized to move the pick roller and the turn roller. 
     
     
         14 . The system of  claim 12 , comprising a turn roller motor to rotate the turn roller, wherein the turn roller motor is separate from the motor coupled to the pick roller. 
     
     
         15 . The system of  claim 12 , wherein the speed to be utilized by the pick roller is based on the type of print media and a material of the pick roller.
