7.3 EPU Mode ([FUNCTION CLEAR] + [START] Buttons)
<23LA/23LM/28LM/23HA/28HA Only>
7.3.1

General description

As this equipment complies with the ERU (Easy Replacement Unit) rules, an all-in-one drum cleaner
unit and developer unit (the EPUs) are used, resulting in easy removal and reinstallation.
In addition to this, the auto-fill function of the developer material with the cartridge is adopted.
This EPU mode allows smooth performance in the series of operations (from the counter reset for the
supply items in the EPUs, auto-toner sensor initial adjustment, developer material filling through
automatic gamma adjustment) required at the replacement of the unit.
Notes:
• Be sure to apply this mode only when the replacement is carried out with EPUs.
• Once this mode is carried out, the counters for the supply items in the EPUs are all reset.
Therefore, do not perform this mode when the supply items in the EPUs are replaced as
single ones.
• If the supply items in the EPUs are replaced as single ones at PM (preventive maintenance)
as usual, perform the PM support mode (6S) described in this chapter to reset the life counter
for each supply item. If the developer material is replaced, perform auto-toner sensor
adjustment and automatic gamma adjustment.
7.3.2 Operational flow
The operation flow is shown below.
Advance preparation
A4/LT size paper needs to be placed in the drawer for automatic gamma adjustment to be performed.
Before executing the EPU mode, place A4/LT size paper and then set the paper size of the drawer.
