Outline of Color registration Method
Color registration is performed by reading the correction pattern printed on the belt using the sensor
placed in the sensor shutter equipped under the belt unit. The correction is made by identifying the
pattern using this sensor.
Timing of automatic activation of color registration:
• At the time of switching the power on
• At the time of closing the cover after opening it over 5 seconds
• When over 400 sheets are printed after a color registration was made previously
Correction errors can be caused by the amount of toner which generates the pattern, toner stain
on the sensor, malfunction of shutter opening and closing. However, as an error may not be
displayed on the operation panel, it may be necessary to confirm the error display by forcible
execution of the color registration test function (2.4.1.5.3) using the maintenance utility.
