Lubrication
CAUTION: 1) Lubrication: During parts replacement.
2) Kinds of oil: 1Kg can. (Part No. 19454906001).
Any machine is generally in its best condition when delivered; therefore, it is necessary to try to keep this condition. Unexpected failure occurs due to lack of oil, debris or dust. To keep its best condition, periodically clean the machine and apply proper kinds of oil to each part in which lubrication is needed.
Although the frequency of lubrication varies according to how much the machine is used, at least it is necessary to lubricate before the machine becomes dry. It is also necessary to wipe off excessive oil as it collects dirt.
CAUTION: Do not spray the inside of the printer with lubricants. Unsuitable oil can damage the mechanism.
