The QL Utility is a computer program that allows you to change the printers default
settings.
Normally when using a computer program to print a document, print settings are 
specified in the printer drivers dialog box and then the data is sent to the printer. This 
utility can be used to adjust settings that are more advanced than the printer drivers 
settings.
Use the QL Utility to configure the printer only when the printer is idle. The printer may 
malfunction if you attempt to configure it while it is handling a job.
„Before Using the QL Utility
•Connect the printer to an AC power outlet.•Make sure that the printer driver has been installed and is functional.•Connect the printer to a computer via USB or RS-232C (QL-720NW only).

Re ferenc e
Maintenance of the machine can be performed as required. However, some 
environments require that maintenance be performed more frequently (e.g. in dusty 
conditions).
„Print head maintenance
The DK Roll (thermal recording paper type) used with the machine is 
designed to clean the print head automatically. When the DK Roll 
passes the print head during printing and label feeding, the print head 
is cleaned.
„Label outlet maintenance
If a label causes the machine to jam 
due to glue attached to the label 
outlet, remove the power cord and 
clean the label outlet with a cloth 
dipped into ethanol or isopropyl 
alcohol.
