The property code is printed on head property labels--bar code label and QR code label, each of which is attached to the lower cover and carriage-head flat cable, respectively.
Page 172 Note: When storing the removed head/carriage unit for a long period, put it in the head casing correctly using the following steps. Leaving it out of the casing causes the head nozzles and ink supply ports to dry up so that the head/carriage unit can no longer provide the original performance.
Page 173 4) First fit the front end of the head/carriage unit over the CR support chassis and then set the rear end onto the CR guide rail. Make sure that the hook (see below) provided on the bottom of the head/carriage unit catches the front edge of the CR support chassis and the two rear bosses are fitted in the two cutouts (shown on page...
Page 174 7) Remove the LR fitting jig and LR positioning jig. 8) Untie the CR timing belt loosely tied. First, at the left end, set the belt on the idle pulley. Next, press the idle pulley holder to the right and at the right end, set the belt on the carriage motor pulley.
