Problem

Solution

Switching between

single sheets and
continuous paper
cannot be
performed properly

(continued).

The paper release lever

is correctly set for

continuous paper, but

when the 

LOAD/EJECT

button is pressed, the

platen rofates

backward and the

paper comes off the

sprockets.

When the 

LOAD/EJECT

button is pressed to

load a single sheet from

the paper guide, the

platen rotates in

reverse, the single sheet

does not load, and the

continuous 

paper

comes off the sprockets.

A single sheet may be in the paper guide,
causing the continuous paper to back out
and to come off the sprockets. When
using continuous paper, always make
sure to remove any single sheets
remaining in the paper guide. See
Chapter 2.

The paper release lever may not be in the
proper position. Push the lever back to
the single-sheet position, set the paper,
then press the 

LOAD/EJECT 

button.
