We recommend to set the printer in a clean room. Avoid the presence of dust, paper pieces and textiles. Regularly clean the parts of the printer that are accessed. Using JetLine Pro system the printer works more intesively. That's why we recommend you to read carefully the printer manual and perform the following procedure:

every morning: perform the procedure of nozzle testing using printer service utilities (see your printer manual);
every week: perform the printing heads alignment procedure (see your printer manual).
