from is IRDA-compliant and within the range of operation described in “Printing a
job using FIR” on page 80.

print than following pages.

z Set the PowerSave feature for a longer time period (See “Configuration page” on
page 169). If a page takes longer to print due to complex formatting commands,
changing the PowerSave setting might not improve print speed. You might want to
simplify the page.

overprints, or only a portion of a
page prints.
z Make sure that your program is configured for the correct printer.
z Replace the interface (I/O) cable with a cable you know works to see if the cable is
defective.

guide on the product CD, or go to www.hp.com/support/lj9000
for an HP cable part
number.)
z Set the PERSONALITY item in the Configuration menu to AUTO (See
“
PERSONALITY=AUTO” on page 206). The product might have been set to PCL,
and a PS job was sent to the product, or vice versa.

prints.
