6.4 Maximizing Pen Life

Steps for maximizing pen life

Table 6-3lists steps that will help maximize the life of recorder pens.

	Table 6-3 Maximizing Pen Life
Step	Action
1	Store the chart paper in a cool, clean dry place where the temperature does not exceed 40 °C
	(104 °F) and the humidity is below 65 % RH.
2	Do not expose the pen tip and chart paper to abrasive chemicals or dust that cause excessive
	pen wear.
3	If the recorder is used in a dusty atmosphere, provide a positive ‘clean air purge’ to minimize
	dust particle accumulation on the chart paper.
4	Periodically clean the pen arm using a cotton swab dipped in alcohol. This is more important
	when the recorder is located in a dusty environment and no ‘clean air purge’ is used.
5	Never let the pen tip ride on the chart plate when the paper is not present. Use the pen lifter to
	raise the arm when changing the paper.
6	Keep the door closed while recording.
7	Always cover the pen arm tip with its protective cap when storing or shipping the recorder.
8	Be sure that the chart paper lays flat against the chart plate. Any ripple in the paper will cause
	light pen printing.
9	Be sure the chart hub assembly is pushed onto the motor shaft so that it is flush with the chart
	plate.
