    Temperature regulation

    Please can someone advise me on how to increase the life span of my rollers i have canon ir3170 changed the upper roller and in two weeks it's got deformed and start peeling off? Or is there a way to regulate or control the temperature of the heating system?

    a. Energy Save Mode
    Energy Save Mode is activated/deactivated by a press on the Power Save key. It lowers the fixing temperature and thus reduce the power
    consumption. The rate of saving is selectable in user mode [Common Settings> Energy Save Mode (-10%, -25%, -50% and no return time].
    b. Low Power Mode
    Low Power Mode will shut off only the +24V power supply and will automatically be shifted from standby after the predetermined time has lapsed.
    The period of time until Lower Power Mode starts can be specified in user mode [Timer Settings> Low-power Mode (10 min. to 4 hours)].
    The fixing temperature is controlled at 140 degrees C and a specific period of recovery time will be required.
    c. Sleep Mode
    Sleep Mode will lower the power consumption below the two modes above. It is activated when the control panel power switch is turned OFF or
    after the predetermined time has lapsed. The period of time until Sleep Mode starts can be specified in user mode [Timer Settings> Auto Sleep Time (10 min. to 4 hours)]. The fuser is turned OFF and a specific period of recovery time will be required. This mode can be turned OFF in service mode [COPIER> Option> USER> SLEEP> 0 (1: ON by default)].
    Note:
    Since Low Power Mode cannot be turned OFF in accordance with Energy Start Program although Sleep Mode can be, the host machine will shift from standby to Low Power Mode after 4 hours at the longest. If Sleep Mode is activated and the period of time until Low Power Mode starts is shorter than that of Sleep Mode, the host machine will shift from standby to Low Power Mode and then to Sleep Mode. However, in the contrary case, the host machine will shift to Sleep Mode without shifting to Low Power Mode.

    Prevention of Partial Deformation of the Roller (otherwise caused by no use over time)
    The fixing roller can start to suffer deformation if left alone for a long time under temperature control (because of its nip). To prevent deformation, the machine rotates the fixing roller at 68.5 mm/sec (half speed) for a period of 0.5 sec every 30 min (during standby).

    When the machine starts sleep mode, the machine turns off the power to the fixing motor (M11) to prevent the fixing motor from rotating; however, since the machine does not perform temperature control for fixing in sleep mode, the roller will not suffer deformation even when it remains stationary.
    The machine performs temperature control for fixing while it is in power save mode (-50%) or in low-power mode, and turns off the power to the fixing motor (M11), thus preventing the fixing roller from rotating. If such a condition lasts for 4 hr or more, the roller can start to suffer deformation; the machine, however, is designed to shift to sleep mode before the passage of 4 hr so that the roller cannot start to suffer deformation.

    That's how long before you throw the whole copier in the trash.

    In the 6800 series there is a setting in service mode to shorten the time between rotations of the fuser when it's idling. I can't remember it offhand, but it helps on that machine. It also helps to reduce the nip pressure.

    adjusting fixing temperature in service mode [COPIER> Option> BODY> TEMP-TBL> set to "1" or "2"].

    Use it to adjust the fixing assembly control temperature.
    0: OFF
    1: +5 deg C
    2: -5 deg C
    The new settings become valid only when the main power switch has been turned
    off and then on. [at time of shipment/after RAM initialization: 0]
