c. Hard points in blades. Whenever the cutter has suffered an impact, such as falling onto the
floor, the blades mark themselves creating a hard point.
d. Excessive friction in the mechanism of the cutter.
Paper has jammed
Remote troubleshooting
●
Check that the customer has followed the paper troubleshooting procedures described in the user's
guide. If not, help him or her to do it.
●
If the jam occurs with roll or single sheet, check with the customer that the output tray is closed.
The printer does not allow printing or loading roll or single sheet with the Output Tray open (a
message appears on the Front Panel). However if this is the case it is likely that the Output Tray
Sensor is broken. Ask the customer to run the Output Tray Sensor diagnostics (see
2.6 Output Tray
Sensor on page 111). If the diagnostics fail, arrange a service engineer visit to replace the
Output Tray Sensor (see
Output Tray Sensor Assembly on page 286).
●
If the jam occurs with roll, and the output tray is closed, check with the customer whether the jam
occurs at the beginning of the print, because due to the paper curling the paper is stopped into
the Output Tray (does not fall into the basket), provoking a paper jam. If this is the case, check
with the customer whether the ribs in the Output Tray have risen or not. If these ribs are not up
while printing from roll, it can cause paper jams at the beginning of the plot. If this is the case,
arrange a service engineer visit to replace the Output Tray.
●
If the problem persists it is probably a mechanical problem that should be diagnosed by a service
engineer. Arrange a service engineer visit to diagnose the issue.
Onsite troubleshooting
The service engineer should first follow the paper troubleshooting in the user's guide, and also the
instructions in this manual given to the customer by the call agent, to double-check that the
troubleshooting has been done correctly. In most cases the problem can be solved by following these
instructions. However, if the problem persists, remove the covers and try the following steps:
1. Check that all the Pinchwheels are all present and well assembled; check also that all the
pinchwheel springs are in place.
2. Check that the starwheel rail is correct.
3. Check that the spindle is not broken or inserted incorrectly, and that the spindle gear is OK.
