Correcting output quality problems
Printer 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 desired paper size and type.
z The size of paper requested is not loaded in the tray selected. The printer 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 optional Tray 4 and did not turn the printer off when
installing it, the printer does not recognize it and draws paper from the next default
tray source. Turn the printer off, then back on, and the printer will recognize the
tray.
Printer interface problems. Print a configuration page from the printer control panel to verify that the interface
configurations shown on the printout match those on the host computer (See
“Configuration page” on page 155 ).
Printer is paused. Press P AUSE /R ESUME . The printer control panel should display READY and the Ready
light should be lit. Resume printing.
Printer is off or not connected to
an active power source. Make sure that all power cables are firmly plugged in to both the printer components
and an active power source. Make sure the printer is on.
Printer is ready, but not receiving
data (the Data light does not
blink). z Check for loose I/O cable connections at the printer 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 printer 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 155 ).
