Printer Mechanism to prevent the assembled parts from loosening due to vibration during the
transportation or assembly operation of the Printer. Therefore, whenever the M-321 0 is dis-
assembled for parts replacement, etc., be sure .to apply the Neji Lock #2 (G) to the specified
bonding points by referring to Table 4.2 or Fig. 4.1. (The bonding point numbers shown in
Table 4.2 are idp.ntical to those shown in Fig. 4.1.)

bly apply the adhesive over 1/2 to 1/4 of the screw head.
