Using Self-Test - TransAct Epic 430 Maintenance Manual

Operational Procedures

Using Self-Test

Self-Test Mode allows you to perform a series of tests to show if the printer is
functioning correctly.
TM
The Epic 430 has several Self-Test options. Some are designed to be useful
when performing on-site print evaluations. Others are designed for factory
setup by TransAct.
To enter self test, press and release the TEST button, a small tool may be
necessary.
Once in test mode, the FEED button is used to select the test to be run. There
are six available testing options. The first three are used to verify basic printer
operation. The last three are options are for factory test.
Testing the printer
The testing options are as follows:
Operation –Ticket Print
This test is the primary test option used when determining if the printer is
functioning correctly.
The Ticket Print Test is mostly used during the early stages of troubleshooting,
to eliminate the possibility that the problem is occurring with the printer. If the
printer experiences a failure, and the error indicator light is activated, call
TransAct's Technical Support department.
Operation - Head Test
This test performs a test pattern that will activate all of the printing elements
and verify that the drive roll is free from defects or debris. The print head has
two heating elements per dot position. A print element is not considered bad
unless both elements are missing. If the head test shows that there is an
inconsistency in the print there may be debris on the drive roll. Cleaning the
drive roll may correct the problem. If this does not correct the problem,
contact TransAct's Technical Support department.
Operation - Marker Calibration
The printer is equipped with several sensors in the paper path, which are
adjustable and will handle a wide range of paper under normal operation.
However, if there appear to be problems associated with any sensor's
operation, the Marker Calibration test will attempt to adjust the sensors for
optimal operation with the paper installed. The Top-of-Form, Paper Out and
Jam sensors will be recalibrated. To run this test, simply select it. The printer
will automatically position the paper and adjust the sensors. If the paper
installed does not have black dot markings, the Top-of-Form sensor will be
adjusted based on the white level of the paper only.
