5.  Maintenance 
 
This session presents the clean tools and methods to maintain the printer. 
◼  For Cleaning 
Depending on the media used, the printer may accumulate residues (media
 
dust, adhesives, etc.) as a by-product of normal 
printing. To  maintain the best printing quality, you should remove these residues by cleaning the printer
 
periodically. Regularly 
clean the print head and supply sensors once change a new media to keep the printer at the optimized performance and extend 
printer life. 
◼  For Disinfecting 
Sanitize your printer to protect yourself and others and can help prevent the spread of viruses. 
◼  Important 
-  Set the printer power switch to O (Off) prior to performing any cleaning or disinfecting tasks. Leave the power cord 
connected to keep the printer grounded and to reduce the risk of electrostatic damage. 
-  Do not wear rings or other metallic objects while cleaning any interior area of the printer. 
-  Use only the cleaning agents recommended in this document. Use of other agents may damage the printer and void its 
warranty. 
-  Do not spray or drip liquid cleaning solutions directly into the printer. Apply the solution on a clean lint-free cloth and then 
apply the dampened cloth to the printer. 
-  Do not use canned air in the interior of the printer as it can blow dust and debris onto sensors and other critical 
components. 
-  Only use a vacuum cleaner with a nozzle and hose that are conductive and grounded to drain off static build up. 
-  All reference in these procedures for use of isopropyl alcohol requires that a 99% or greater isopropyl alcohol content be 
used to reduce the risk of moisture corrosion to the printhead. 
-  Do not touch printhead by hand. If you touch it careless, please use 99% Isopropyl alcohol to clean it. 
-  Always taking personal precaution when using any cleaning agent.
