Abstract
A recorder like an ink jet printer includes a head unit, which includes recording head and a head holder. Intermediate members are screwed to the holder. Each of the recording heads is bonded to one of the members and has a number of ink ejection nozzles. After the unit is assembled, one of the heads may be found to be defective. Even in this case, it is possible to remove only the defective head and the associated member, fit a new intermediate member to the holder, and bond a new recording head to the new member with the nozzles of this head aligned with the nozzles of the other heads. The intermediate member has a hole engaging with part of the head with play for positioning the head relative to the holder.
