Carriage
The carriage includes a print head for ejecting ink, and a jam sensor for stopping the carriage when media
clogs. Printing occurs as ink is ejected while traversing left and right.
Capping station
The capping station includes caps for keeping the print head nozzle surface from drying out, a wiper required
for print head maintenance, and an NCU for monitoring print head nozzle conditions.
The NCU (Nozzle Check Unit) automatically checks whether the nozzle is clogged. Setting various functions
enables automatic print head cleaning or printing using other nozzles. "Nozzle check menu"(P. 86)
"Registering Nozzle Recovery"(P. 78)
Pinch Rollers and Grit Rollers
The pinch rollers and grit rollers are used to grip and feed the media.
• When the machine is not in use, raise the clamp lever to separate the pinch rollers from the grit
rollers. Leaving the pinch rollers in the lowered position for an extended period of time may
cause the pinch rollers to become deformed. Deformation of the pinch rollers may prevent the
media from being fed correctly.
