Maintaining the Printer

This chapter contains cleaning procedures and a schedule detailing how often to
perform maintenance procedures. Even though the 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.
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.
