    For best printing results, use the following procedure to clean the print head and rollers with alcohol. Also note that tape adhesive tends to accumulate on the sides of the tape outlet after long use of the QG-100. When this happens, use an alcohol-moistened cotton swab to clean off the adhesive. 1 Open the printer’s cover.

Possible Cause Recommended Action Improper cable connections.
  • Page 25 PRINT key Starts print operation. Adjusts contrast. * The POWER indicator flashes orange for a few seconds while the QG-100 checks the digital camera’s status. The following describe key operations in combination with SHIFT. The operations listed below are performed when the SHIFT indicator is lit.
  • Page 26 The digital camera power may not turn off when you operate its POWER switch if the camera is not connected correctly to the QG-100 or if you perform an improper operation while they are connected. If this happens, use one of the following procedures to correct the problem.
