Printing Or Printout Quality Problems - Epson PLQ-20 Reference Manual

Printing or printout quality problems

The printer is on but it doesn't print.
Cause
The interface cable is broken or
twisted.
The printer is not connected
directly to your computer.
The printer driver is not
installed correctly.
Paper is jammed or the ribbon
or guard mechanism is stuck.
The USB setting is incorrect.
The printer is hung-up
(stopping in abnormal
situations).
What to do
Check that the interface cable is not
broken or twisted. If you have another
interface cable, replace the cable and
check whether the printer works
correctly.
When you use a printer changer, printer
buffer, or a extension cable, the printer
does not print correctly due to the
combination of these devices. Make sure
that the printer works correctly when it
is connected to your computer without
these devices.
Check that the printer driver is installed
properly. If necessary, reinstall the
printer driver.
Turn the printer off, open the printer
cover and remove the jammed paper or
things that are stuck. To eject the
jammed paper, see "Clearing Paper
Jams" on page 119.
Confirm the USB setting is correct. See
"Correcting USB Problems" on page 115
for details.
Turn the printer off and wait for a while.
Then, turn the printer on again, and start
printing.
