 Troubleshooting

205

•

Check that the side of the spindle is not bent, here is an example of a bent side plate. 

•

Check the stand tensions (2metal cables in X linking each legs) are well tensioned. Re-tension it if 

needed. 

•

Check that the drive roller is not dirty. Here is an example of drive roller which has to be cleaned. 

•

How to clean the drive roller: from service menu, run ‘1.3.1 Turn Drive Roller’, using a soft cloth 

damped with isopropyl 70% or equivalent cleaning liquid. It can take a long time to do a good 

cleaning, up to at least 1 hour. 

•

Check that all the pinch wheels are rotating well (pinch wheels open, checking with finger). Clean 

the pinch wheels if needed, using a with soft cloth damped with isopropyl 70% or equivalent 

cleaning liquid. 

•

In case of intermittent media wrinkles, check that the distance between the Media input spindle and 

the main drive the roller is the same on the left and right side. Same check to be done between the 

output spindle and diverter. In case of any difference, check that the side plate is well positioned. 

Here are the 2 alignment pins to be check, on each side plate (pointed out by a red arrow).

•

Check that there is no visible source of air leakage within the vaccum beam under the printzone:
•

Check that the connection of the vacuum pump tube to the beam is correct.

•

Check that the forklift guide is correctly in place with all the screws (or there could be an air 

leakage through the holes maintaining the forklift guide within the vacuum beam).
