Epson Action Laser II - Manual (Page 180)

Options
Several sheets feed into the printer at one time and jam (the FEED JAM
or
PAPER JAM message appears on the display).
You may not be fanning and tapping the stack of paper
sufficiently. Remove the jammed paper following the
instructions earlier in this chapter. Before reloading paper, be
sure to tap the paper and even up the edges of the stack. Also, do
not load paper that is creased or folded.
You may not be using the correct paper for your printer. Make
sure your paper matches the specifications listed in Chapter 8. If
the finish of the paper is too smooth or too rough, paper feeding
may be difficult. Try feeding each sheet manually.
The thickness of the paper also affects paper feeding. Always test
your paper before purchasing it in large quantities.
Using an optional interface, the printer does not operate as
expected.
The printout is garbled
or
the printer does not print.
Your computer may not be properly connected to the printer.
Perform the section on Testing the computer-to-printer
connection in Chapter 2. If the test shows an improper
connection, go on to the next three troubleshooting items below.
If the test shows a proper connection, skip to the last item in this
problem category.
The interface may not be configured correctly. If you are using a
serial interface, make sure that both the computer and printer are
set to use the same number of data bits per word and that they
both use the same parity, baud rate, and number of stop bits. See
your computer manual for the correct settings.
You may also need to change the DIP switch settings of your
interface board. Before changing these settings, however, make
sure the printer is turned off.
