An Optical Mark Recognition (OMR) system detects and reads marks made on paper. It uses a scanner to capture the image of a marked form, and then processes the image to interpret the marks accurately. The system compares the marked answers to a pre-defined answer key to determine accuracy.

Jel pen ink may be too thick or appear as a smudge on OMR sheets, making it difficult for the scanner to read the marks accurately. OMR scanners are designed to read pencil marks or thin pen marks more effectively because they create clearer and more consistent marks on the paper.
The technology used to read pencil or pen marks on a multiple choice answer sheet is called Optical Mark Recognition (OMR). OMR scanners detect marks made by pencils or pens through the reflection of light. These marks are then converted into digital data for processing and analysis.
An optical mark recognition (OMR) device is capable of recognizing pre-specified marks made with a pencil. It uses light to detect marks on paper forms filled in by respondents using a pencil, specifically in multiple-choice questionnaires or surveys.
The types of mechanical work include static work, dynamic work, and intensive work. Static work refers to work done without motion, dynamic work involves movement, and intensive work focuses on the internal energy changes within a system.
Input work is the work done on a machine, while output work is the work done by the machine. Efficiency of a simple machine is calculated as the ratio of output work to input work. The efficiency of a simple machine is high when the output work is close to the input work, indicating that the machine is converting most of the input work into useful output work.
