Missing Ink Or Low Density Ink Band Running
Length of Print
Possible missing or weak jet.
1. Print the Service Test Print 2, Weak/Missing Jets, to determine
if a jet is not performing. Perform up to three printhead
cleaning cycles to try to clean a clogged jet.
2. If necessary, turn off the printer and allow the printhead to cool
for a minimum of 4 hours.
3. Ensure the printhead maintenance vacuum system operates
correctly.

printhead.
Scratches parallel to the long axis of printing
Usually caused by foreign debris in the paper path.
1. Run a sheet of paper through the manual feed to see if the
scratch appears on the print. If it does not, the scratch occurred
in the paper pick and early transport of the paper.
2. A scratch or smear caused by the paper preheater can be
caused by debris built up on the heating surfaces. Run the front
panel cleaning procedure Remove Ink Smears. Additionally, you
can manually force a sheet of thick 65 to 80 lb. paper through
the paper preheater to “buff” the paper preheater heating
surfaces. With the leading and trailing ends of the sheet of
paper extending from the entry and exit of paper preheater,
gently pull the sheet of paper back and forth several times and
then remove the sheet of paper. Be careful of the paper sensor
flags.
