HP Designjet T1120 MFP Product Series - Scanner Maintenance

About Scanner Maintenance
Scanner maintenance will ensure continuous optimal performance of your scanner. There are three basic maintenance tasks:
Scanner maintenance will ensure optimal performance of your scanner. There are three basic maintenance tasks:
  1. Cleaning
    Keep your scanner clean – How often you need to clean will depend on how often and the types of media you scan. If your work primarily involves scanning newspapers and old blueprints you may need to clean more often than users who only scan brochures and new drawings. Be sure to clean the scanner when results are not optimal. Particles of dust in the scan area can sometimes be the sole cause of streaks in the end result. To reach the scan area, you need to flip back the touch screen and open the lid. The scanner must be powered off before opening the lid. You must clean the scanner glass and internal rollers.
  2. Calibration
    Calibrate the scanner if your output is not optimal and cleaning (above) does not remedy the problem. Calibration will renew the scanner’s original color and BW precision. Scanner Calibration is easy to perform. To run, you insert a Calibration Sheet, and start the Scanner Maintenance program. The rest is done by the program. Make sure the scanner is clean before calibrating.
  3. Replacing the glass plate
    This should be carried out when a worn glass plate affects your results. You may need a new glass plate if streaks still appear on the image even after cleaning the glass. To change the glass plate, you need to flip back the touch screen and open the lid. The scanner must be powered off before opening the lid. Follow the instructions that came with your new glass plate.
