Cautions on the Ink Cartridge / Maintenance box CAUTION  Do not touch IC chips on the ink cartridges or Maintenance box. Doing so may cause operating/printing malfunction.  This product uses ink cartridges equipped with an IC chip that monitors the amount of ink used by each cartridge. Cartridges are usable even if they are removed and reinstalled. However, if an ink cartridge in which little amount of ink remains is removed and reinstalled, it may not be usable. Some ink is consumed each time cartridges are installed because the product automatically checks their reliability.  Install all ink cartridges. Printing is not possible even if only one ink cartridge is missing.  Since ink cartridges are designed to stop the operation before ink runs out completely to maintain the quality of the print head, some ink remains in the used ink cartridge.  All the ink colors are consumed also for the maintenance operations when an ink cartridge is replaced and for print head cleaning.  Flashing (Power) LED indicates that head cleaning, ink charging, or printing is in progress. Do not open or close the Roll paper cover, Ink cartridge cover, or Maintenance box cover, or turn off the power.  Do not turn off the product or open the ink cartridge cover while charging ink ( (Power) LED is flashing). Opening the cover may cause the ink to be recharged, resulting in more ink being consumed. Also, it may cause printing malfunction.  Even for monochrome printing (printing of monochrome image), all the ink colors are used in an operation designed to maintain the printing and print head quality.  Do not disassemble the ink cartridges or Maintenance box, or supply or replace ink. If you disassemble them, ink may get into your eyes or adhere to your skin. It may also prevent you from printing correctly. Ink may leak and damage the printer.  Do not remodel the ink cartridge. Doing so may cause printing malfunction.  Use of an old ink cartridge may result in reduced print quality. Use it up within six months after opening the package. The usage period for ink cartridges is printed on the packaging of individual ink cartridges.  Do not reuse a maintenance box which has removed and detached a long period.  Store the ink cartridges or Maintenance box out of the reach of children. Do not drink ink.  If ink contacts your skin, eyes, or mouth, take the following actions.  When it gets onto your skin, immediately wash the area with soap and water.  When ink gets into your eyes, immediately flush them with water. Leaving the ink as is may result in bloodshot eyes or mild inflammation. If something is wrong, immediately consult with a doctor.  When ink gets into your mouth, immediately spit it and consult with a doctor.  Be careful when handling the ink cartridges or Maintenance box as if ink leaks and adheres to clothes, it may not come off even after washing it.  There may be some ink around the ink supply port on the removed ink cartridge. Take care so that it does not stain the desk or other surface.  Do not remove the ink cartridge or maintenance box, except when you replace it.  Do not open the ink cartridge package until you are ready to install it in the product.  Do not shake the ink cartridges or Maintenance box strongly. If you shake or swing them strongly, or push the sides strongly, ink may leak from the cartridges or Maintenance box.  Do not push the supply port of the ink cartridges or Maintenance box as ink may leak. 6
