UV
lamp (bulb) life depends on many factors including number of starts,
thermal operating conditions, power rating, additives and proper
handling. Simply defined, it is the hours the lamp produces enough UV
energy to properly cure the ink within the available exposure time.
The
initial 200 to 250 hours of operation (idol time plus active print
time), the UV output is stable. Between 250 and 450 operation hours,
output decreases, eventually resulting in insufficient UV curing
energy. Some inkjet printers have the ability to change lamp power
settings. Switching to medium or high power increases UV output,
however heat is also increased. There may be a fine balance between
acceptable UV output and heat generation. Another option is to maintain
heat loading by slowing print speed while the UV lamp is at low power.
This option is mostly available with standard mercury filled lamps.
Some lamps are additive filled. They produce higher levels of UV;
however, they do not last as long and normally cannot be run at low
power.
Each lamp startup reduces UV lamp life.
Adjust printing schedule to keep lamp starts to a minimum. The fact
that the lamp lights is not an indication of proper UV output. Most UV
lamps will continue to operate long after their useful life has expired.
Warranty
period is for 1 year after date of invoice or hourly guidelines
whichever comes first.
- Subzero
mercury filled lamps 450 hours
- Subzero
additive (gallium, iron iodide) filled lamps 400 hours
Under
normal conditions, the vast majority of TCS Technologies lamps will
provide at least 500 hours of useful life. In the unlikely event of
failure, pro-rata credit will be given based on the number of lamp
hours. For example, a Subzero mercury lamp, which fails after 225
hours, would result in 50% credit.
This warranty applies to lamp only and
cannot be expanded or modified. This warranty is in lieu of all other
warranties expressed or implied and of all other obligations or
liabilities on its part. All shipping costs for replacement
consideration are the responsibility of the customer
Warranties do
not cover the following customer related responsibilities:
- Accidental breakage
- Surface contamination; this is the
major source of any lamp failure, including fingerprints.
- Bowed lamps
- Poor lamp connection as indicated
by discolored end fittings.
- Distorted and overheated tubing
and overheated foil seals.
- Normal lamp ultraviolet drop off
does not indicate lamp failure
- Lead wires burned off. Maximum
allowable temperature is 200ºC
All
shipping costs for replacement lamps are the responsibility of the
customer.
This warranty is restricted to
replacement of the lamp only and TCS Technologies shall not be
responsible for any other damages, consequential or otherwise.
