Page 148 (10) Unlock the connector on the carriage PCB and disconnect the head flat cable. Note After disconnecting the flat cable, check that each cable is not damaged at its end or short- circuited. When connecting the flat cable, do not insert it at an angle. Lock the connector, after confirming that the cable is not at an angle.
Page 149 (13) Pull out the head joint spring to the right. (14) Pull the head joint up and off the head/carriage unit. Immediately, wrap the head joint in a clean, lint-free cloth and keep it higher than the ink refill ASSY to prevent ink remaining in the ink supply tubes from leaking and the machine from getting stained with leaked ink.
Page 150 (16) Move the head/carriage unit slightly to the right as shown below. (17) While pressing the idle pulley holder to the right, remove the CR timing belt from the carriage motor pulley and the idle pulley.

Page 153 (24) The head/carriage unit is assigned a property code which indicates the unit's properties. This code is encoded in the QR code label affixed to the head/carriage unit and the bar code label affixed to the lower cover. When you remove the head/carriage unit and store it separately from the machine, remove the property label (bar code label) from the upper cover and store it together with the head/carriage unit.
Page 154 Note When storing a removed head/carriage unit for a long period, put it correctly inside the head casing by following the procedure below. Leaving the head/carriage unit outside the head casing for a long period will dry the print nozzles and ink supply ports and will make the head unusable. 1) Set the head/carriage unit on the head casing (lower), then slide it to the right.
Page 155 4) Fit the front end of the head/carriage unit first over the CR frame and then set the rear end onto the CR guide rail. Make sure that one point (see figure below) on the front side of the head/carriage unit bottom is firmly hooked to the front end of the CR frame and that the bosses of the bottom rear side are properly fitted into the two notches of the CR guide rail (refer to page...
Page 156 7) Remove the LR (Leveler Roller) fitting jig. 8) Release the bound CR timing belt and attach it to the idle pulley on the left edge first. Then, while pressing the idle pulley holder to the right, attach the belt to the carriage motor pulley on the right edge.
