General Maintenance 17
2.0 General Maintenance
This section describes procedures for general maintenance and cleaning of the SST3 printer.
2.1 General Cleaning
During normal operation, media debris may accumulate around the printer mechanism inside the printer. This
debris should be removed regularly using a soft bristle brush and/or vacuum cleaner.
2.2 Cleaning the Printhead
Foreign particles can collect on the printhead, causing characters or bar codes to appear light or faded. This type
of problem is evidenced by a continuous light streak which appears in the same physical position on each printed
line. This condition should only appear after extensive printer operation or if poor quality paper has been used. It
is recommended that Rice Lake Weighing Systems-supplied labels are used to obtain continuous high quality
printing.
Recommended printhead cleaning intervals:
• Due to abrasion and foreign particle deposits, direct thermal printheads should be cleaned every 50,000
linear inches (approximately eight rolls of labels) (12700m).
• Thermal transfer printheads should be cleaned at least every 250,000 linear inches (approximately 40
rolls of labels).
Printhead cleaning procedure:
1. Unplug printer from the outlet.
2. Open cover. Unlock and raise printhead.
3. Gently wipe underside of printhead burn-line area using a cotton swab moistened (not soaked) with
isopropyl alcohol. Allow to dry.
4. Lower and lock printhead.
5. Close cover. Plug in and turn on printer.
