Troubleshooting 46
PAPER JAM
Problem
A paper jam occurs when during printing, paper feeding, or paper cutting,
and the carriage is not able to move properly (due to paper catching on
some part). The printer determines a paper jam has occurred if the Front
and Rear Paper sensors are ON but the carriage motor is out of step or
drawing too much current.
Solution
After removing the jammed paper, turn the printer off and back on
again.
If a paper jams occurs again after removing the original paper jam,
check to make sure nothing is blocking the feed path or blocking the
carriage.
COVER OPEN
Problem
The front cover is open.
This error occurs when the cover is opened during carriage operation or a
cleaning operation, causing printer operation to stop. If the carriage is not
in home position and the cover is left open too long, the printheads may dry
out and become damaged. (To avoid this problem, press the Pause button
before opening the cover. Note that if you continue printing, a stripe or
band may appear where printing resumes; this is because the previously
printed section has had more time to dry than the freshly deposited ink.)
Solution
Close the cover as soon as possible.
If the cover is fully closed when this error occurs, make sure the left
and right cover-open sensors are correctly installed and are operating
properly.
PAPER NOT CUT
Problem
The paper that was supposed to be cut was not cut completely, or the
paper was cut but is still in front of the Front Paper Sensor.
Solution
Remove the cut paper if it is on or near the Front Cover and Lower
Paper Guide.
Replace the cutter if it is worn out.
If the paper was cut, but not cut straight across, you may need to
adjust the cutter position. See
Cutter Position Adjustment on
page 131 for details.
PAPER NOT STRAIGHT
Problem
This error occurs when the printer detects that the paper is skewed (loaded
at an angle) by more than 3 mm. If the printer prints on paper that is loaded
at a slant, the printer may print outside of the printable area and may fire
ink onto the platen. If this happens, the next sheets loaded in the printer
may be marred on the back.
Solution
Remove the paper loaded in the printer and properly reload it so that
it’s edge is aligned with the vertical line of holes in the Lower Paper
Guide.
If using roll paper, remove the roll and carefully squeeze the sides of
the roll to make sure they’re lined up and flat.
