CHECKING SUPPLY QUALITY

The printer continuously stores data from the most
recent 16 supplies printed. This checks the reflectivity
of the sensor marks on the supply. Before you check
your supply quality, print a batch of supplies or test
labels. Use Sendfile version 2.19 to check your
supply quality. This test can also be performed using
the optional 917 Keypad.
To check your supply quality from the optional
keypad:
1. From the Diagnostics menu, press
you see
DIAGNOSTICS
User Diag.
2. Press . You will be at the User Diagnostics
menu. Press or
USER DIAG
