1.2 Troubleshooting of Error Codes
1.2.1 Preparation
Before repairing the equipment, check the following items.
Operating Temperature:
(1)
The equipment is placed in a flat and stable place.
(2)
Use the equipment in a clean environment with a temperature of 10°C to 32°C and a relative humidity
between 20% and 80%.
(3)
The equipment is not exposed to direct sunlight, excessive heat, humidity, or dusty environment.
(4)
When moving the device, please grasp the handle at the bottom of the device and lift the device from
the front.
Figure 2-1
Power:
(1) The power supply value meets the regulations on the equipment nameplate.
(2) The power supply voltage fluctuation range is within ±10% of the rated voltage.
(3) The input AC power is within the specified value.
(4) The cable and patch cord are connected correctly.
(5) The fuse is not blown.
Paper:
(1) Use recommended paper.
(2) The paper is not damp.
(3) No short grain or acid paper is used.
Consumables:
(1) Drum Unit (including Toner Cartridge) installed correctly.。
Other:
(1) Condensation
When the device moves from a cold place to a warm room, condensation may form inside the
device, which may cause the following problems:
• When condensation occurs on the surface of optical components such as lenses, mirrors, and
protective glass, the printed image may become lighter.
• If the temperature of the photosensitive drum is too low, the resistance of the photosensitive
layer will increase, making it impossible to print with the correct print density.
• Condensation on the charging unit may cause corona charge leakage.
• Condensation on the bottom plate or separation pad may cause paper feeding problems.
If condensation has formed in the device, please leave the device for at least two hours until the
device temperature rises to room temperature. If the drum unit is moved from a cold place to a
warm room, the package is immediately opened, the condensation that may be generated
