After a period of time, the belt may be aging and relaxation, resulting in image printing offset. You can use screwdriver and inner hexagonal wrench to adjust screws at the two positions of the machine, so as to re-tighten the belt.

Make sure that the base of the machine has good friction with the table so that the machine does not jump when it is working.


If it is not used for a long time, we suggest adding some anti-rust oil to the metal places such as the screws and bearings of the machine to avoid metal rust, and package it in a dry environment to avoid rust!
