What can I do if the Printer has problems with Media Loading?
1 Check that the Media Sensor is installed correctly.
2 Check if the cable for the Media Sensor is connected correctly.
3 Check if the Pincharms are down (the Pincharm lever should be up).
4 If the media is continuously rejected during the media edge check, then
make sure that the Line Sensor is installed correctly. If necessary, perform
the Carriage Test ' page 4Ć12.
5 Make sure the line sensor is calibrated. Perform the Accuracy Calibration
' page 5Ć2.
6 Replace the Media Sensor (part of the overdrive assembly) ' page 8Ć50.
7 Replace the Carriage Assembly ' page 8Ć37.
Only replace one component at a time and check if the problem
has been solved before replacing another component. Using
this procedure you will be able to determine exactly which
component failed.
What can I do if the Printer has problems with the Cutter?
1 If the Carriage Assembly has problems picking up the Cutter:
D Check that the cable for the FrontĆPanel Assembly is is not loose and is
routed correctly in the cover clips. A loose cable can be trapped by the
Cutter, preventing the Cutter from moving.
D Make sure that the Spittoon Assembly is correctly installed and is
aligned with the Overdrive Assembly. If the Spittoon is loose or
mispositioned, the cutter will have problems parking in the right cover.
2 If the media crashes when moving the Cutter:
D Make sure that there is no media trapped inside the Cutter
mechanism. Remove the Cutter to inspect it correctly.
D Remove the Cutter and make sure that both rotary blades are touching
each other by the flat sides and not the sloping sides. If the rotary blades
are touching each other by the sloping sides, you must reseat them.
D If the Printer is placed on a table, it must be placed as close to the edge
as possible to make sure that the media that is coming out falls
correctly. If the Printer is in the middle of the table, the media that is
coming out will be lifted up causing the cutter to crash into it.
