Fig. 5-1. Location of rollers, bearings, and rail

The carriage rail carries the printhead carriage across the width of the platen. As dust and ink accumulates on the rail, the mate- rial could accumulate on the carriage bearings (wheels) and cause banding in printed output or noisy (“click-click-click”) carriage motion.

Pinch Rollers 1. Wipe the pinch rollers with a lint-free cloth or wipe moist- ened with isopropyl alcohol.

Caution DO NOT ALLOW ISOPROPYL ALCOHOL TO TOUCH THE PRINTHEADS, especially the inkjet orifice plates. Contact with the ink could cause the ink to coagu- late, rendering the printhead unusable and requiring it to be replaced. Be sure that cleaned surfaces have dried before printing.

2.Clean the grit rollers.

Select Maintenance > Clean Grit Rollers from the menu. This advances the grit rollers continuously so they can be cleaned with a lint-free cloth or wipe moistened with iso- propyl alcohol.
