Maintenance work should be regular in order to keep the printer in good condition and achieve high quality prints every time. Some parts require maintenance before each print and some every few hundred working hours. All maintenance activities do not take much time and they are not complicated. Before commencing any repair it is extremely important to turn off the printer and let it cool down. Remember to always wear safety gloves and glasses.
