EPSON Stylus COLOR 1520


After removing the CR unit, do not touch and damage the heads. Protect the heads from static
electricity, because the head drive circuit is directly attached to the head board.


Pay attention to the oil pad when removing the CR guide shaft from the CR unit. It tends to
dislocate.


When installing the CR guide shaft to the printer mechanism unit, be sure to fit the platen gap
adjust lever to the right frame assembly. (Refer to the figure below.)


Perform platen gap adjustment, Bi-directional adjustment, and Uni-directional adjustment after
installing the CR unit and parallelism adjust bushings. (Refer to Chapter 4.)


If the printheads are replaced along with the CR unit, be sure to write head data to the EEPROM.
(Refer to Chapter 4.)


When engaging the timing belt to the CR unit, note 2 parts of the belt: flat part and tooth part. Be
sure to position the 2 parts of the timing belt as shown in the figure below.
