Problems and solutions
If you can't make a print
Note
When using a printer with a Lower Tray Assembly, make sure 
that the door covering the upper slot is closed before you try to 
make a print from the lower tray.  You cannot print from the 
lower tray with the door open.
Printer not operating
Make sure that you have plugged in the printer and turned it on.  Make sure 
that you connected the interface cable properly.  Make sure that the line 
voltage selector switch is set properly. 
Press the TEST button on the back of the printer for three seconds.  If the 
printer produces a test print, the printer is functional and the next step is to 
verify that your computer can communicate with the printer.  If the printer 
fails to produce a test print, make sure that paper is loaded and a transfer 
roll is installed.  If you have paper and transfer roll installed and the printer 
does not produce a test print, the printer requires service.
Note
When you have checked all possible causes and your printer is 
still not operating, you can call for service at 1-800-835-6100 in 
the U.S.A. and Canada, or call your Tektronix dealer.
