1. Uncap the print head and move the carriage unit to the center of the main unit (p.267).
• When the carriage unit is moved, ink may spill out from the print head onto the platen. To
move the carriage unit, place a sheet of plain paper under the carriage unit to protect the
platen.
• The sheet under the carriage unit should be flat, with no paper wrinkling, which could scratch
the nozzle face or cause clogging of the nozzle.
• Do not place any film under the carriage unit.
• To place the plain paper, do not pull up the paper holding lever too much (p.226).
2. Remove the top cover (p.245).
3. Remove the front cover (p.249).
