2. Disconnect the following connector cables from the connectors on the main board assembly:
CN3
CN13 CN14 CN18 CN20 CN21 CN22 CN23
3. Disconnect the ASF PW sensor connector cable from the PW sensor connector on the left edge guide
of the ASF assembly.
4. Remove 7 screws (6 CB screws, 4X14 and 1 CBP screw, 3X8) securing the printer mechanism unit to
the lower housing.
The connectors for the motor (CN20,22 and 23) and for the ink cartridges (CN7, 12, 13 and
14) look similar. Therefore, be sure to connect them properly, since inappropriate connection
may result in malfunction of the PSE/PSB board or the main control board.


Be sure to lubricate the top surface of the paper eject frame in an ASP printer
mechanism unit, since the frame, along which the CR unit slides, is not lubricated.


After installing the printer mechanism unit to the lower housing, be sure to insert the
waste ink draining tubes linking to the pump unit into the sub waste ink drain pads. (See
Section 3.2.11.7.)


After replacing the printer mechanism unit, perform required adjustments to write
appropriate values such as head data and several adjustment values into the EEPROM
on the main control board. (See Chapter 4.)
