SECTION 3
OPERATING PRINTER
35
DIAGNOSTICS Screen
Use to help troubleshoot and identify Printer issues by
running tests on Printer components and systems.
Use selections (1, 2, 3, 4), at bottom of screen, to control
speed (1 = slowest, 4 = fastest).
CAUTION : Printer transport will run and printer will feed
when TEST is activated. If media is present, it will be fed.
Before pressing “ TEST ”, please be sure that printer has been
properly setup to feed the media you plan to use.
Press
“TEST”
to start the diagnostics cycle. Button will
change to “ STOP ”.
Press “ STOP” to stop the diagnostics cycle.
Sensor
(Media Sensor indicator)
: Use to test Media Sensor. With at least one piece of media loaded, press TEST to
activate diagnostics cycle. SENSOR indicator should turn ON (green, interrupted) as media passes through media
sensor and OFF (not interrupted) when no media is present at media sensor. Press “STOP” to end test.
TIP : If Sensor condition does not change as media feeds through the sensor; Stop Test. Shutdown and Power OFF
the Printer and clean the Media Sensor. Then Re-test.
Encoder (count & indicator) : Use to test the transport systems Encoder signal. Remove media from system. Press
TEST to activate diagnostics cycle. Indicator should turn from RED to GREEN if there is any Encoder activity
detected. Encoder value (count) should also increment as transport turns. If Indicator stays RED, while transport
system is turning, then there is a problem with the Encoder signal. Press STOP to end Test. Contact tech support.
Piece Length : Use to check accuracy of media transport. First, verify that “Clutch w/Sensor” is selected (checked).
With one piece of media loaded, press TEST to activate diagnostics cycle. After feeding one piece of media, verify
that the piece length was measured accurately (+ - 0.1”). Press STOP to end Test.
If the piece length measured longer than the actual piece length, the media is probably slipping or hesitating as it
feeds. In this case, check/adjust the Media Thickness setting.
If the media feeds through, but no piece length is displayed, check the Media Sensor and the Encoder.
TIP : An accurate Piece Length value also indicates that the Media Sensor and Encoder are performing properly.
Piece Count : Counts the number of pieces of media that have been fed during the current diagnostics test session.
TIP : If there is a problem with the Media Sensor, the Piece Count will not increment as media is fed.
Transport
(speed)
: Use to check system transport speed. Shown as inches per second (IPS), in above image.
TIP : If there is no Encoder signal, there will be no Transport speed measurement.
Clutch (signal indicator) : Displays status of the Clutch activation signal.
OFF = Clutch not activated. ON (green) = Clutch activated. Feed rollers should be turning.
TIP: If Clutch signal is ON (green) and transport system is turning, but feed rollers are not turning, this may indicate
a problem with the Clutch, Clutch signal/connection or other Feeder components. Contact tech support.
Clutch w/Sensor (check box) : Select how the Clutch is activated during Diagnostics Tests.
Unchecked – Remove media from system. Press TEST. The transport system will run and the feed roller Clutch will
be activated (ON/OFF) using an automated routine. Do NOT feed media during this test.
Checked: Loaded media. Press TEST. The transport system will run and media will be fed with a short pause in-
between each piece. As Media Sensor is interrupted, by the media, the Clutch will be deactivated; stopping
additional pieces from feeding. Once media passes the media sensor (sensor not interrupted), the Clutch will be
activated and another piece will be fed. This process will continue until you press STOP or run out of media.
