Common Procedure for Scanning Test Chart

When the test chart needs to be scanned, follow the procedure below.

  1. Clean the exposure glass and place the test chart so that the bar-code printed on the chart positions to the left.
  2. For secure contact between the exposure glass and chart, put approximately 20 sheets of paper on top of the chart. Make sure to match the corners of the paper and exposure glass.

    • [A]: Scanner
    • [B]: Chart
    • [C]: Paper

  3. Press the Scan button for the adjustment required on the NICE main menu screen.
