Head/carriage unit and CR timing belt
NOTE:
During the removal or installation job for the head/carriage unit, take care not to
contaminate the PF encoder disk with ink or grease.
(19) While pressing the idle pulley holder to the right, remove the CR timing belt from the carriage
motor pulley and idle pulley.
(20) Move the head/carriage unit to the left end of its travel by hand.
(21) Lift the head/carriage unit (with the CR timing belt) up and off the engine unit in the direction
of the arrow shown below.
NOTE
: Do not touch the head nozzles (the printing ends) or ink supply ports (to which ink
supply tubes are connected) of the head/carriage unit; doing so will not only stain your hands
with ink but also damage the nozzles and supply ports. If you do touch them though, clean
them with a special-purpose cleaning stick and liquid.
NOTE
: Do not remove the CR timing belt from the head/carriage unit unless it needs to be
replaced. Once removed, the belt will become unusable and a new one will have to be put back
in. For the early version of machines which has a spacer film between the CR timing belt and
the head/carriage unit, be sure to sandwich the film inbetween when setting a new belt to the
head/carriage unit as shown below.
NOTE
: If the head/carriage unit needs to be replaced, replace not only that unit but also the
CR timing belt. In this case, do not sandwich the spacer film any more even on the early
version of machines.
