Head/carriage unit and CR timing belt
Note:
During the removal or installation of the head/carriage unit, take care not to contaminate
the PF encoder disk with ink or grease.
(17) While pressing the idle pulley holder to the right, remove the CR timing belt from the
carriage motor pulley and idle pulley.
(18) Move the head/carriage unit to the left end of its travel by hand.
(19) Lift the head/carriage unit (with the CR timing belt) up and off the engine unit in the
direction of the arrow shown below.
(20) Remove the CR timing belt from the head/carriage unit.
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,
perform a head cleaning operation.
Assembling Notes:
• When handling the head/carriage unit, put on a grounding wrist band and perform the job
on a static mat. Also take care not to touch the conductor sections on the flat cables.
• When mounting the CR timing belt, insert it into the slit provided in the head/carriage
unit so that the toothed side faces inwards as shown above. Make sure that the belt is
fully inserted inside the latches.
When mounting a new
head/carriage unit, apply
grease to the CR support chassis
(11 lubrication points).
