 Troubleshooting

215

•

Check that the Pinch Wheel mechanism is correctly installed (described next). 

•

Check that the Drive Roller is no slipping versus the advance motor (described later). 

1.

Check that the black plastic knob is fully inserted. Pass to the customer the procedure for when insert-

ing a new Printhead Cleaner, focus mainly on when closing this black plastic knob: NEED FIRST TO 

RELEASE THE TENSION of the Printhead cleaning material, BY ROTATING ANTICLOCKWISE 

THE UPPER ROLL, containing the new material and then rotating the black plastic pinch wheel to 

close the printhead cleaning roller. 

2.

Check that the two vertical metal supports on each side of the axis of the ‘pinch wheel roller’ are not 

too bent. 

If the two vertical metal supports are bent, unbend them using pliers (the pliers should not be too small). 

In case one of the vertical metal supports is bent beyond repair: 

•

When closing the black knob, it can push slightly too much on the edge of the Printhead Cleaning 

Roller material, creating wrinkles on the horizontal part. 

•

The pressure applied on the Printhead cleaning roller material might not be sufficient, causing the 

material to slip and subsequently causing intermittent Printhead Cleaning Roller jams.
