Correcting output quality problems
Product draws paper from the
wrong tray. z Be sure your program is selecting the correct paper size or type.
z Make sure that the driver for your program is correctly installed, configured, and
capable of requesting the required paper size and type.
z The size of paper requested is not loaded in the tray selected. The product draws
paper from the next default tray that contains the correct size. Load the correct
paper in the tray and make sure the tray is adjusted correctly. Load the tray with
enough paper to complete the print job.
z If you selected Tray 2, 3, or Tray 4 and did not turn the product off when installing
it, the product does not recognize it and draws paper from the next default tray
source. Turn the product off, then back on, and the product will recognize the tray.
Product interface problems. Print a configuration page from the control panel to verify that the interface
configurations shown on the printout match those on the host computer (See
“Configuration page” on page 169 ).
Product is paused. Press S TAR T . The control panel should display READY and the Ready light should be
lit. Resume printing.
Product is off or not connected to
an active power source. Make sure that all power cables are firmly plugged in to both the product components
and an active power source. Make sure the product is on.
Product is ready, but not receiving
data (the Data light does not
blink). z Check for loose I/O cable connections at the product and computer or network
port.
z Try your I/O cable on a system that you know works.
z Check that the correct interface cable was selected and is securely connected to
both the product and the computer. If the cable is not correctly configured, see the
star t guide for configuration information.
z If connected to a network, print a Jetdirect configuration page to check for
interface or network problems (See
“Configuration page” on page 169 ).
