MAINTENANCE
Important:
The quality of print units is assured about two years after production
under unpacking conditions.
Caution:
The print unit is very sensitive to light. When shaking the unit to
make toner uniform or replacing the unit, note the following:
• Do not expose the print unit to direct sun light or strong light
(about 1,500 luxes or more). Do not leave it even under ordinary
room light for five minutes or more.
• Do not expose the drum to light.
When replacing the print unit, be sure to replace the toner bottle
too. It is better to perform the following set of procedures when
replacing the print unit:
• Remove the old print unit. (Never detach the toner bottle from the
print unit before removing the print unit from the printer.)
• Clean the paper path.
• Clean the transfer charger wire.
• Install the new print unit, then the new toner bottle.
Caution:
Do not return the toner remaining in the old print unit to the toner
bottle to reuse the toner for the new print unit. It may cause a
printing trouble because such toner contains harmful foreign matters
like paper particles. Be sure to replace the old print unit with the
toner bottle mounted.
The following sections describe these procedures in the order listed.
