Troubleshooting

b.

If the looseness of the substrate is occurring in the media output, from time to time slide a sheet 

of paper (Letter-A4 size) within the roll, on each side of the output roll, at the same time, in 

order to add tension on the edge.

c.

Then apply the standard changes (reducing temperature, quantity of ink, …).

3.

In case of oblique wrinkle and a high tension on the edge (situated towards the cartridge side) and 

less tension on the side closer to the e-cabinet: there is a high probability that there is a bow on the 

input spindle (- and these wrinkles can pass the pinchwheels and reach the print zone). 

a.

Check the maximum diameter of the substrate (should not be more than 25cm) 

b.

Check the weight of the substrate: maximum weight, single spindle, (not the dual roll): 

- 110kg for the L65500/LX600 and 
- 130kg for the LX800) 

- (for dual roll: 100kg for 104”, 120kg for 126”)

In case one of the above items does not comply with the specification, this could be the cause of the 

issue. There is no official accessory from HP to support heavy/narrow rolls, as a workaround the 

customer could support the middle of the roll (using a metal ‘empty core’ + support in the middle of 

the spindle, which had to be adjustable in height). 

4.

Look at the print zone, and check that the substrate is flat, that there are no bubbles between the 

drive roller and the print zone. (open the side window)
