It shouldautomatically reach this position after a few seconds of printer inactivity. The purpose for this is to tightly sealthe print nozzles to prvent the ink inside from drying-out.Note: If the personal computer is powered off while the printer is still on, the printer will automatically resetitself.If the printer is powered off during the reset phase, the print head may stop outside its parking position.It is therefore suggested to power off the printer before the personal computer.DATASTROBEBUSYACKTackT s T dT dT sbT ba.
