100 Compugraph Operator Interview Questions and Answers

  1. What is a compugraph?

    • Answer: A compugraph is a legacy term referring to a system or device, often involving specialized hardware and software, used for creating and manipulating graphical representations of data, typically for producing charts, graphs, and other visual displays. The specifics varied greatly depending on the era and manufacturer.

  2. Describe your experience with various types of plotting devices.

    • Answer: (This answer will vary based on the candidate's experience. A good answer would mention specific types like pen plotters, inkjet plotters, laser plotters, and possibly even early digital display systems, detailing their experience with each type and any troubleshooting they've performed.) For example: "I have experience with HP pen plotters, specifically the HP 7475A model. I'm familiar with loading pens, calibrating the plotter, and troubleshooting paper jams. I've also worked with inkjet plotters, understanding the importance of maintaining the print heads and ensuring proper ink levels."

  3. How familiar are you with different file formats used in compugraph systems?

    • Answer: (This answer will vary. A good answer would mention several formats like HPGL, DXF, possibly older proprietary formats, and their characteristics.) For example: "I'm familiar with HPGL (Hewlett-Packard Graphics Language), a common format for pen plotters. I also have experience with DXF (Drawing Exchange Format), which allows for greater interoperability between different CAD software and plotters."

  4. Explain the process of setting up a compugraph job.

    • Answer: The process involves selecting the appropriate plotter, configuring the paper size and orientation, choosing the correct pen types, loading the paper, sending the job to the plotter, monitoring the plotting process, and addressing any errors that might occur. This often includes using specific software drivers and interfaces to manage the communication between computer and plotter.

  5. How would you troubleshoot a paper jam in a pen plotter?

    • Answer: I would first turn off the plotter and carefully unplug it. Then, I would open the access panel to identify the location of the jam. I would gently remove the jammed paper, ensuring not to damage the plotter mechanism. After that, I would inspect the paper path for any obstructions and carefully reload the paper, making sure it's properly aligned. Finally, I would power on the plotter and try to resume the plotting job.

  6. Describe your experience with different types of plotting media.

    • Answer: (This answer needs to be tailored to the candidate's experience. A good response might cover various paper types, film, and other materials suitable for different plotters and applications. ) For example: "I have experience with various plotting media including standard bond paper, vellum, and mylar film. I understand the differences in their suitability for different ink types and plotter technologies."

  7. How do you ensure the accuracy and quality of plotted outputs?

    • Answer: Accuracy and quality are ensured through proper plotter calibration, using high-quality plotting media and inks/pens, and verifying the plot file for errors before processing. Regular maintenance of the plotter and checking for any mechanical issues are also crucial.

  8. What software packages are you familiar with for generating compugraph outputs?

    • Answer: (This will vary, but should include CAD software and potentially specialized graphing programs.) For example: "I have experience using AutoCAD, and I'm familiar with generating plot files from various CAD packages."

  9. Explain the concept of scaling and resolution in plotting.

    • Answer: Scaling refers to adjusting the size of the plotted output relative to the original design. Resolution refers to the density of the plotted points or lines, impacting the detail and quality of the output. Higher resolution typically yields better detail but might increase plotting time.
