E. IU life setting
• Comparing the "PC drum rotation time" with the "PC drum rotation time calculated based
on the number of printed pages", the machine detects the end of unit life when either of
them reaches the set value.
• By changing "IU life setting" in the "system setting - 2/2" in the "service mode", a desired
threshold for "PC drum rotation time" can be selected.
• When IU life is set to "normal", the standard life value is used as the threshold for "PC
drum rotation time". Selecting "Normal" is appropriate when the machine is under normal
use (Default setting).
• When IU life is set to "Long", the longer life value is used as the threshold for "PC drum
rotation time".
• If the machine is under the following conditions, the number of pages that can be printed
by one imaging unit can be increased in some cases by setting IU life to long.
"Page/Job value is low".
"PV/M value is low".
"Color print ratio is low".
NOTE
• Setting IU life to Long cannot always increase the number of pages that can be
printed by one imaging unit.
• When IU life is set to Long, print images are out of guarantee if they are produced
after the IU life counter goes beyond the number described in the product specifi-
cations.
• Before changing the IU life setting, be sure to check that any warning message is
not displayed to let the user know that the imaging unit, fusing unit, or transfer
belt unit reaches the end of life. If the IU life setting is changed while a warning
message is displayed, unit change screen may appear and printing can be
stopped.
• After changing the IU life setting, be sure to turn OFF the main power switch and
turn it ON again more than ten seconds later.
