The roll may need to be replaced or reloaded.
The roll is unloaded unexpectedly
In the cases below an excess of friction is causing a malfunction in the media input which causes the ,edoa
roll to unload unexpectedly.
One of the main causes of friction is that the sides of the paper are brushing against the hubs for different
possible reasons, such as:
●
Media has expanded due to climatic conditions (for example, switching off Air Conditioning).
●
Poor quality media with telescoping, core is narrower than media.
Call agent:
1. Ask customer if the issue has happened while printing. If so, refer to 39.11:01 Media unloaded
(Advisory) on page 121 troubleshooting.
2. Upgrade the printer to the latest firmware.
3. Ask customer to open roll cover and feed media into the media path.
a. Check if the sides of the media roll are brushing against the hubs. If they are, tell customer to
reposition the media roll on the spindle ensuring some margin (≈3mm) between the sides of the
media and the black and blue hubs and check that it does not brush against the hubs anymore. If
this is not the case, continue troubleshooting as below.
b. Visually check that the hubs (black and blue pieces) are not broken. If they are damaged, send a
new spindle to the customer.
