Troubleshooting

Here is a picture showing the black Printhead cleaning pressure roller (it might be black of orange), with 

the small on each side. The pikes of each 2 elements have to match. 

(The distance should be less than 1.4mm as shown in the 2nd picture). If more than 1.4mm is seen, replace 

this sub-assembly. 

Check each rib of the Printhead cleaning pressure roller: it should be straight, no defect. Here  is  an 

 example  of  defect,  in  the  middle  of  the  round  circle. If  such  issue  is  seen,  replace  this  part.   

Check that the small gears connected to the lower axis are not broken. Here  is  a  picture  of  these  small 

 gears  (2  identical  gears).

Perform a ‘Check and Clean’ from the IPS (go to the printer tab, Printhead cleaning), you can look at the 

Printhead cleaning roller, and check that the static wipe is working correctly, by looking at the Printhead 

cleaning roller (front right sliding door open).
