Problem Solving
1. Printing misaligns toward the bottom of my form (skews).

Ensure the LEFT paper guide is squared by sliding it all the way to the
right against the paper rack stop.

Take your time in properly aligning the form, being sure to slide it in until it
stops against the feed rollers. The printer beeps up to 3 times (default is
one beep).
2. Frequent Paper Jams.

Flatten any curl at the leading edge of the form by folding it in the opposite
direction. The printer will more readily tolerate leading edges that are
slightly curled down rather than curled up.

Make sure the control panel knob for form thickness is set to AUTO.
 Excessive paper thickness. Maximum allowable thickness is .020”
3. Printing speed is slow.
Press the SPEED key to select a higher speed mode.
LQ NORMAL
HIGH 2 HIGH 1
4. Printing is light.
Check the ribbon cassette condition.

If the surface of fabric becomes whitish, replace the cassette with a new
one.
When using multipart forms:

Change SPEED to LQ

Press the HIGH IMPACT key to select “DARK”.

Make sure carbonless forms have not exceeded their shelf life. Try fresh
forms.
5. When menu item #25 PAPER SKEW DETECT is set to YES, (factory default
is NO) cut sheet paper is ejected with a SKEW ERROR message on the LCD,
even though paper is loaded straight.
Dark black areas printed on the paper or the paper is narrower than 4 ½
inches.

Set menu item #25 PAPER SKEW DETECT to “NO”.
