Oiling Criteria
► Initial Lubricant: Initial Lubricant Only
6M: Once every six months
1Y: Once a year
1. Oiling rules
▪ Check the lubrication before starting or storing printers or MSCRW. If any part is
insufficiently lubricated, lubricate it according to the oiling criteria.
▪ Lubricate the part only when it is necessary during field regular inspection. If
lubrication is sufficient, no additional oiling is required. If the oil is dirty, remove it
and lubricate again.
▪ Make sure to lubricate all pivot points and friction parts.
▪ Lubricating parts: All equipment operation parts excluding printing head, package,
micro switch contact point, drive roller, timing pulley and timing belt.
▪ As a general rule, apply oil by dropping the oil onto the part. If the edge of oil
feeder has to touch the surface of the object, do not have the oil feeder touch the
part for more than a second.
2. Warnings
▪ Do not apply oil if it oozes out from the designated place. Do not over-lubricate
since it can contaminate other parts, or flow into other parts or splash.
▪ Be sure that lubricant does not contaminate micro switch, sensor, timing pulley,
timing belt, package, printing head.
▪ Do not scrub the plastic parts or protection parts with alcoholic substance or other
solvent.
▪ Use a piece of soft and dry cloth when removing dust, oil or grease, or cleaning
the part or the assembly parts.
▪ Be careful that the paper contact side in the paper return path is not wet with oil.
