PAPER JAM

Problem
A paper jam occurs when during printing, paper feeding, or paper cutting
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 P-Front
sensor and P-Rear sensors are in the "on" state but the CR motor is out of
step or has overcurrent.
Solution
After removing the paper stuck in the printer, the "TURN OFF AND
ON" message appears on the display. The printer is ready after you
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 the CR/PF operation and ink sequences to
stop. If the cover is left open too long, the printheads may be damaged. (To
avoid this problem, press the Pause button before opening the cover. But
be aware that a stripe may appear on the printout indicating the different
drying times.)
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.
Troubleshooting

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 P-Front sensor.

PAPER NOT STRAIGHT

Problem
This error occurs when the printer detects the front and rear edges to be
skewed (the paper is loaded at an angle/slant) by more than 3mm. 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 have marred reverse sides.
Solution
Troubleshooting Using the Error Messages
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 need to adjust the
cutter position. See "Cutter Position Adjustment" on page 140 for
details.
Remove the paper loaded in the printer and properly reload it
according to the instructions in the user's guide.
For roll paper, the edges of the paper may not be lined up; (remove the
paper) and carefully squeeze the sides of the roll to make sure the
edges are lined up and flat.
