Stocking Up On Laser Drums
Buying laser printer drums in a bulk can save money and
time. When there is a need, all you got to do is to fix it in the printer and
let the printer do its job. But buying drums in a wholesale, in quantities that
the office might not be able to consume through before the drum expires, is a
waste of money and space.
Laser drums have shelf lives. Shelf life is the time that a
drum remains usable if the packaging remains sealed. It is important that the
printer drums are left in their protective bag for them to remain usable. Most
printer drums have a shelf life of two years.
Protective Bags No More?
If the Printer drums are exposed and or the seal of their
protective bag is broken, their shelf life is reduced to six months. This goes
for all printers, be they an HP, a Sharp or a Xerox Dubai. Try to use that unsealed drum as soon as
possible. If the drum remains in storage and unprotected beyond six months then
to dispose of it is the best idea. Unused unsealed and expired drums can damage
the printer function and should not be used at all.
Resealing The Bag
If the bag has been opened up mistakenly it should be
resealed by using a tape or glue. Usually when the bag is sealed by the
manufacturer, a jet of nitrogen gas is used to displace the air inside the bag.
The bag is quickly sealed so that the nitrogen gas remains inside the bag.
Nitrogen is among the most inert gasses in the periodic table and so it protects
the drum from rust, dust or microscopic corrosion. When the seal is broken, the
Nitrogen escapes the bag allowing the moisture in the air to interact and
damage the drum. Nevertheless, in case the seal is broken, tape up the opening
and store the device in a cool, dark and dry place. Assure that the temperature
remains between 0⁰C and 40⁰C and the humidity is somewhere between 35%
to 85% to extend the life of the drum.
