  • Page 29 L565/L566 Series Revision A MEANS DO TO MINIMIZE THE INK SPILL Even observing the points described in this section, ink may spill in the following situations. Therefore, be careful not to contaminate the inside of the printer or its surroundings by preparing the container to receive the leaked ink, or the like.
  • Page 30 The photos in the following procedure are for L/365/L366,L360/L362,l220/L222 Series, but the procedure for L565/L566 Series is the same; the numbers of the tube and the location of the Ink Supply Tank Assy in the photos are different from those of L565/L566 Series, though.
  • Page 31 L565/L566 Series Revision A Discharging procedure 1. Release the Ink Supply Tank Assy.(Refer to Discharging preparation (p.30)) 2. Place the Ink Supply Tank Assy on a place where its bottom is higher than the top of the Printhead. 3. To minimize the ink leakage from the Ink Supply Tube / Ink Supply Tank Tube , pinch the Ink Supply Tube / Ink Supply Tank Tube with clips (x 2) .
  • Page 32 L565/L566 Series Revision A It is recommended that the ink in the Ink Supply Tank should be discharged completely before proceeding to disassembling/reassembling. After all the reassembling work is complete, the discharged ink of each color should be refilled back to the Ink Supply Tank before performing the adjustment. Confirm the colors indicated on the film of the Ink Supply Tank so as not to mistake them, and make sure to refill each ink back to the correct tank from the corresponding ink supply hole.
