Preventative Maintenance Recorder Paper Replacement
Sealed Lead Acid
Due to the self-discharge characteristics of sealed lead acid batteries, it is imperative that
they are charged after 3 months of storage (or unit not in use). If not, permanent loss of
capacity may occur as a result of sulfation. Charge retention at 20
o
C is 6 months to 83%.
Lithium-Ion
Storage of the lithium-ion batteries depends on temperature, time period and the degree of
cell charging state. After 6 months of storage at 23
o
C, fully charged lithium-ion batteries
have a retention capacity of 93%.
5.12 Recorder Paper Replacement
The instructions below describe the replacement of recorder paper. Use only recommended
recorder paper, part number 0683-00-0422-XX. This ensures that the print quality is
acceptable and reduces print head wear.
1. Open the recorder door by pressing the paper eject button.
2. Remove the empty paper spool.
3. Insert a new paper roll between the two rounded tabs of the paper holder, with the
sensitive (shiny) side of the paper facing the print head at the top of the recorder (paper
feeding off of the spool from the bottom).
4. Unroll approximately 4 inches of paper.
5. Align the paper across the top of the roller.
6. Holding the paper in place, close the recorder door.
7. To ensure that the paper is aligned properly and has not been pinched in the door, pull
the loose edge out a couple of inches. If the paper jams, open the door and return to
step 5.
5.12.1 Care and Storage of Thermal Chart Paper
Thermal Chart Paper is chemically treated and the permanency of a recording is affected by
storage and handling conditions. These conditions are:
• Ultraviolet Light
We recommend storing the recordings in a filing cabinet within a few days of printing. Long
term exposure to natural or artificial U.V. sources is detrimental.
• Storage Temperature and Humidity
Keep the recordings in a cool and dry area for a longer lasting image. Extreme temperature
and humidity (above 80° F/26° C and 80% humidity) should be avoided.
• Solvent Reactions
Do not store the recordings in plastic bags, acetate sheet protectors, or similar items made
from petroleum products. These products emit a small amount of vapor which will, over a
period of time, deteriorate the image on the chart paper.
