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 Lor Runtil you see

DIAGNOSTICS
l User Diag.	r

2.Press E. You will be at the User Diagnostics menu. Press Lor Runtil you see

USER DIAG

Supply Quality r

3.Press E. If you have not printed any labels, the message “No data! Press Enter” appears.

If you have printed labels since turning on the printer, you will see

Len Min Max OK

l1568 034 124 Y r

The Len listing is the length of the loaded supply in dots. The Min listing should be greater than the Max listing when

∙white is under the sensor.

∙a die cut label gap is under the sensor.

The Max listing should be greater than the Min listing when

∙black is under the sensor.

∙the solid black area of a die cut label is under the sensor.

The OK listing tells whether the sense mark on the supply passed a detection test. Press Rto see the other readings.

If you are not using a Version 5.2 sensing system and you try to check the supply quality, the message “HW not supported” appears.
