This chapter contains procedures for testing the printer’s performance as a quality
check during preventive maintenance, as a functional check when troubleshooting,
and as part of the repair process after replacing a printer component. This chapter
also contains procedures for making adjustments and alignments that ensure the
printer is operating normally.
Testing the Printer
If you are on site for preventive maintenance or are following up a corrective
action and the printer is working, start conducting quality checks from the Test
and Service mode. If you are on site for corrective maintenance, determine if
the problem lies with setup and process or the printer itself. Use the Test and
Service mode to determine if the printer can print. If it can, perform the
communications test.
The quality and efficiency of producing labels reveals if a printer is operating
correctly. In addition to analyzing labels to evaluate printer performance, the
3600 printer Test and Service mode allows you to conduct printer tests that
include printing test labels (illustrated in this section) with a fixed look so you
can compare them to an expected standard. The test labels can be used for
checking printhead alignment, printhead bias, dots out of specification, label
tracking, and ribbon wrinkling. Test and Service mode functions can be run at
the printer or from a host terminal through the use of commands.
If you find a printer lacking in performance after running your tests, check and
make the adjustments and alignments necessary to return the printer to normal
service. If you cannot get a printer working properly with an adjustment or
alignment, troubleshoot for a component failure.
Note: Making the alignments out of order can introduce, not solve printing problems.
Review the section about printer alignments before making any changes.
