Note:
oFor the parts marked with (*1) to (*6), new wire bands are required when assembly, since the 
following wire bands used for those parts will be cut during disassembly. See the disassembly steps for 
the position of the wire bands.
(*1): Wire band (SKB-85)

(*5): Wire band (SKB-85) 
´ 2
(*6): Wire band (SKB-85) 
´ 2 and wire band (SKB-1.5M) ´ 1
The wire bands given below are the identical ones.
• (*2) and (*3) wire bands (SKB-85)
• (*4) and (*6) wire bands (SKB-1.5M)
• (*5) and (*6) wire bands (SKB-85)
oWhen you replace the cut sheet presenter module
, the paper exit
, and the upper frame 
cut sheet presenter unit
, a seal, paper exit guide
 is required for each part.

   ·Hold the cable for the cut sheet presenter module 7.5 cm from the 
connector while aligning it with the frame inside edge of the paper roll 
supply module.
   ·When you pull the cut sheet presenter module fully to the near side with 
your fingers on/around the
 seal, paper exit guide, the cable should have 
a little slack. (It should not be stretched out.)
   ·The cables for the printer module should not be run together.
