Actuation of pick mechanisms for media stack height sensing based on number of printed sheets

A method comprising:

• receiving, by a processor, a print job;
• receiving, by the processor, a first sheet count before printing of the print job;
• receiving, by the processor, a second sheet count after printing of the print job;
• determining, by the processor, a number of sheets printed during the print job based on a difference between the first sheet count and the second sheet count;
• updating, by the processor, a pick mechanism activation counter value based on the determined number of sheets printed;
• determining, by the processor, whether the updated pick mechanism activation counter value is greater than or equal to a predetermined threshold value;
• and
• based on a determination that the updated pick mechanism activation counter value is less than the predetermined threshold value, preventing, by the processor, an operation of a pick mechanism to determine a media stack height of print media in a print media tray.

A non-transitory computer readable medium on which is stored machine readable instructions that, when executed by a processor, cause the processor to:

• receive a pick mechanism activation counter value;
• receive a first sheet count before execution of a print job, the first sheet count being a count of printed sheets before execution of the print job;
• receive a second sheet count after execution of the print job, the second sheet count being a count of printed sheets after execution of the print job;
• determine a number of sheets printed for the print job based on a difference between the second sheet count and the first sheet count;
• update the pick mechanism activation counter value by incrementing the pick mechanism activation counter value by the determined number of sheets printed;
• and
• one of:
• based on a determination that the updated pick mechanism activation counter value is greater than or equal to a predetermined threshold value, allow an operation of a pick mechanism to sense a media stack height of print media;
• or
• based on a determination that the updated pick mechanism activation counter value is less than the predetermined threshold value, prevent the operation of the pick mechanism to sense the media stack height of the print media.
