Canon iR Advance 400iF/ 500iF Image smear/toner bleed/condensation

Postby Serviceman » Sat Oct 28, 2017 11:52 am

Models list: Canon imageRUNNER ADVANCE 500iF, 500i, 400i, 400iF
Image Failure: Image smear/toner bleed/condensation
Location
Photosensitive Drum (circumference:94mm)

Cause
Discharge products generated from the Charging Roller adhere to the Drum, attract water molecules and cause low resistance, which loses the ability to create the desired latent image, resulting in bleed text image.

Condition
The first operation in the day under a high temperature and high humidity environment

Field Remedy
• Service mode (Lv.2)> COPIER> OPTION> ENV-SET> IMG-BLD1> 0 to 3
0: OFF
1: Extend warm-up rotation for 60 seconds
2: Extend for 120 seconds
3: Extend for 240 seconds
• When "1-3" under "Service mode(Lv.2)> COPIER> OPTION> ENV-SET> IMG-BLD1" are set, the item is displayed in the user mode.
Only setting value "2" can work in the user. [Settings/Registration]> [Adjustment/Maintenance]> [Clean Drum]> [Start]
• Install an option Drum Heater
