E Lubricate the Guide Rails
The guide rails may be dry when you receive
your printer, so check and lubricate the guide
rails before your first print.
Only use a high quality thin sewing machine oil
such as Singer Oil (the product shown here).
The use of incorrect lubricant may cause the
bearings to dry up and cease.
1).The cross rails have ball bearings inside and only
require very little lubrication. Lubricate the two
cross guide rails with only a small dab of lubricant.
2).Lubricate the four guide rails around the printer
framework.
Notice: Lubrication is very important for good
printing performance, or else you might encounter
printhead stuck problem.
