Maintaining the Printer

This chapter contains cleaning procedures and a schedule detailing how often to
perform maintenance procedures. Even though the 4420 and 4440 printers can
withstand harsh environments, you must clean them on a regular basis to maximize
performance. It is very important to perform the maintenance procedures if you
expose the printer to dirt or debris. For help replacing media or ribbon, see
Chapter 1, “Getting Started,” and Chapter 2, “Operating the Printer.”
Inspecting the Printer
Inspect the printer and the rest of your data collection system equipment on a
regular basis. Your inspection should include these tasks:
•
Make sure you have properly grounded the printer.
•
Inspect the work environment. Large electric motors, welders, and
switching equipment can affect printer performance.
•
Check the data collection network regularly for loose wires or poorly
installed connections. Be sure to replace corroded wires.
