(II) Paper feed motor side wiring
(3) Printer unit and bottom case unit assembly
In assembling the printer unit chassis into the bottom case unit, be cautious of the following points to protect the
waste ink tube from being pinched:
(I) At replacement of the platen unit (QM2-2202), purge unit (QM2-2208), waste ink tube (QC1-6458), or waste
ink tube holder (QC1-6460), fix the waste ink tube to the printer chassis and waste ink tube holder with tape (at
2 locations).
If the tube is pinched and blocked, proper purging is prevented, resulting in ink leakage or strange noise.
(No specific tape is specified. In the sample photo below, (1) is the orange tape, and (2) is a clear adhesive tape,
such as Sellotape or Scotch tape.)
