4. Check the +15 reference by reading pin 24 (+15V) on the connector
block (see Figure 5-14). The +15V signal should read between the
minimum and maximum values shown below:
This completes the performance verification for the programming
electronics assembly.
If any of the measurements described above are outside the specified
ranges, contact Data I/O Customer Support as listed in the Preface.
Running the Self-test
You cannot access the self-test command from TaskLink’s operator mode.
To perform a self-test you must be in TaskLink’s administrator mode. To
start this self-test, perform the following steps:
1. From the DOS prompt, start TaskLink in administrator mode by
entering

Preventive Maintenance Procedures For Operators
This section provides the ProMaster 2500 operator with a guideline for
routine preventive maintenance. By following these procedures for
cleaning each of the components along the device path, you can ensure
that the 2500 will continue to function properly. Maintenance at the
operator level is limited to the adjustment or cleaning of each of the listed
components.
Note: Maintenance intervals are based on operation of the ProMaster 2500 for
40 hours per week with a throughput of 40,000 devices per month.
To clean the 2500, you will need the following items:
• Lint-free cloth
• TriFlow
®
lubricant
•DeoxIT
™
Pen
• Solvent that has been approved for use by your company
• All-purpose spray cleaner
•Isopropyl alcohol
•Cotton swabs
• Compressed air
Note: These procedures recommend cleaning printer parts with a mild cleaning
solvent (such as isopropyl alcohol). Be sure to choose a solvent that has
been approved for use by your company.
