IBM 1800409-001A - Manual (Page 65)

CAUTION: The OPC belt is extremely sensitive to bright lights
and direct sunlight. Do not remove the cartridge from its protective
bag until you are ready to install it. Limit exposure to light of 800
lux (the average fluorescent lighting in an office) to under 2
minutes. If exposure exceeds this, put the belt into a dark place,
like inside the printer, to recover; depending on exposure, recovery
may take up to 2 hours.
Also, handle the belt cartridge carefully. The belt is extremely
sensitive to hand oils and scratches, both of which will reduce print
quality.
2. Remove the OPC belt cartridge from its protective bag.
NOTE: Be sure to save the protective bag to use during printer
cleaning and maintenance when the OPC belt cartridge is out
of the printer.
