Hello Harvy. The ET-5800 is an inkjet printer. So, if the printer sits without usage for periods, you can run into issues with the print head. If printing at a low volume, to be safe, we recommend doing user maintenance, such as nozzle check printouts every few days. Nozzle checks use very minimal ink and let you see the print head's status and run head cleanings if necessary. Please see the User's Guide on our official Epson Support page for more helpful maintenance information. Regards, Kevin - The Epson Team.
