15.1.1 Initial Check
0019-5081
Check the following items before you diagnose malfunction. If any failure is found, a service engineer is to clear the problem and to give the instruction to a user.
Installation environment
- The power voltage is -/+10 % of the rated voltage.
- The machine is securely installed on a level surface.
- The room temperature is kept between 10 and 30 deg C, and the relative humidity, between 10 and 80 %.
- Avoid sites generating ammonia gas, high temperature or high humidity (near water faucet, kettle, or humidifier), cold places, open flames, dusty area and sites
the wind blows in from the air-conditioning duct.
- Avoid sites exposed to direct sunlight. If unavoidable, advise the customer to hang curtains.
- A well-ventilated place.
- Make sure that the power cord is inserted to the machine and the outlet securely.
Paper checks
- The recommended paper for the printer is used.
- Paper is not damp.
- Paper is not dirty.
Paper sets
- The amount of paper in the pick-up source is within specifications.
- Paper is correctly set on the selected pick-up source.
- The size guides are aligned with paper.
Cartridge sets
Make sure the toner cartridges in each color are set in the machine properly.
Fixing unit sets
Make sure the fixing unit is set in the machine properly.
External cover sets
Make sure the front cover is closed securely.
Condensation
During winter, if the machine is brought from a cold place such as a warehouse into a warm room, condensation will appear inside the machine, causing various
problems.
Ex.)
a. Condensation in the optical system (polygon mirror, reflective mirror, lens, etc.) will result in a light print image.
b. As the photosensitive drum is cold, the resistance of the photoconductive layer is high; this will lead to incorrect contrast.
If condensation appears, either wipe the parts with dry cloth, or leave the printer on for 10 to 20 minutes.
If the toner cartridges are opened soon after being moved from a cold room to a warm room, condensation may appear inside the cartridge and may cause various
problems.
Be sure to instruct the user that it is necessary to leave the printer for one to two hours at a room temperature to allow it to acclimatize to the temperature.
