Oiling Criteria
► 1. Oiling rules
- Check the lubrication before starting or storing printers or MCRW. If any part is
insufficiently lubricated, lubricate it according to the oiling criteria.
- Lubricate the part only when it is necessary. 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, magnetic
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 or magnetic head.
