Possible Cause or Remedy
The battery in the ribbon sensing circuit may need to be replaced
(normal battery life exceeds ten years).
A non-Printek ribbon has been installed. While not
recommended, the use of non-Printek ribbons is allowed.
However, only Printek ribbons will allow the ribbon sensing
system and ribbon wear indicator to function. To configure your
printer to be able to use non-Printek ribbons, refer to the
appendix titled "Advanced Control Panel Features".
Worn or damaged ribbon.
Ribbon not installed properly on drive mechanism.
Note: If the ribbon cartridge and/or fabric is damaged, replace it
with a new ribbon. Continued use of a damaged ribbon may
cause damage to the ribbon drive mechanism or the print head.
The form requires the high impact character mode. Set Impact to
High in the form setup menu.
Poor carbon or carbonless form quality. Refer to "Selecting a
Quality Form" later in this section.
Obstruction in paper path. Check both printer and print stand.
Torn or ragged edge on paper.
Paper misaligned in tractors.
Left and right tractors too close to each other allowing paper to
"droop".
Tractor doors not closed.
Paper too difficult to pull from box (dragging on sides of box).
Remove forms from box or cut away sides of box.
Tractor blocking paper out detector.
Poorly constructed forms. Refer to "Selecting a Quality Form"
later in this section.
The printer's input buffer has been exceeded. Check the
interface setup to assure that the handshaking or flow control
method required by your computer has been selected. Also
check the cabling for proper pin-out or broken wires.
A serial character was received with improper parity. Check the
interface setup to assure that the parity (odd, even, ignored, or
none) is set to match the parity setting required by your
computer. Also check the cabling for intermittent connections
