Thermal paper
Replacement rolls of thermal paper with a width of 2 3/8" (60 mm)
and an external diameter of approximately 2" (50 mm) can be ob-
tained from the machine manufacturer.
When this is stored under the following conditions, the text will re-
main legible for at least 7 years:
- no direct light
- constant room temperature between 64°F (18°C) and 77°F (25°C)
- relative humidity of max. 40–60%
The durability of the thermal printout is reduced by:
- a faulty printer head in the thermal printer
- the thermal printer being set incorrectly; the printout appears faded
- prolonged exposure to temperatures above 105°F (40°C)
- storage in a damp or wet environment over a long period
- contact with emollients, which are found in PVC films, for example
- contact with oils, fats, or alcohol
- contact with aggressive chemicals
- direct sunlight
Unfavorable conditions will cause the text on the printout to fade.
The printout will not be legible and the data to be documented will
therefore be lost.
Avoid all influences which will impair the durability of the thermal
printout.
Prepare a backup copy on thermostable paper if necessary.
