6.9.6 CPM DOWN SYSTEM
CPM Down Control
When this machine gets a sequence of printing jobs at a high line speed mode (205
mm/sec) and some conditions occur, the machine decreases the CPM to prevent offset on
outputs due to insufficient fusing temperature. This mode can be turned on or turned off
with SP1-916-025 (default: "ON").
CPM down mode has two steps (1 and 2).
For a full-color printing job using middle-thick paper, the machine enters step 1, and then
step 2. For other types of printing job, the machine enters step 2 only.
Step 1 (Only for full color mode using middle thick paper)
If the input voltage from IH inverter to the IH coil > 93% (adjustable with SP1-916-26) and
ambient temperature ≤ 17°C (adjustable with SP1-112-001):
 The machine decreases the CPM to 30ppm (adjustable with SP1-916-022) for 20
seconds (adjustable with SP1-916-023).
If input voltage ≤ 93% (adjustable with SP1-916-26) and ambient temperature > 17°C
(adjustable with SP1-112-001):
 The machine decreases the CPM to 30ppm (adjustable with SP1-916-022) for 20
seconds (adjustable with SP1-916-023).
If input voltage ≤ 93% (adjustable with SP1-916-26) and ambient temperature ≤ 17°C
(adjustable with SP1-112-001):
 The machine decreases the CPM to 25ppm (adjustable with SP1-916-022 and
SP1-916-024) for 20 seconds (adjustable with SP1-916-023).
Step 2
When the fusing temperature goes below the print ready temperature for plain paper:
 The machine decreases the CPM to 30ppm (adjustable with SP1-916-020).
When the fusing temperature goes below the print ready temperature for middle thick
paper in B/W mode:
 The machine decreases the CPM to 30ppm (adjustable with SP1-916-021).
6.9.7 ENERGY SAVER MODES
When the machine is not being used, the energy saver feature reduces power consumption
by switching off the fusing lamps. This machine has two energy saver modes.
Level 1 Energy Saver Mode
The default of the level 1 energy saver mode is “Off.” If the user enables it, level 1 energy
saver mode starts 30 seconds after the machine has completed a print. In this mode, the
