Setting the Envelope Sealing Prevention Mode

If the glue on envelope flaps melts and seals due to the heat and pressure of the fixing unit during envelope printing, perform the following operation.
Press  (Settings/Registration)  <Adjustment/Maintenance>  <Adjust Image Quality>  <Special Processing>  <Envelope Sealing Prevention Mode>.
Press <On>  <OK>.
This setting is only enabled during envelope printing.
If this setting is set to <On>, the quality of the image may be adversely affected.
