NOTES: 1. When the printer is not in operation , ma k e s ure that the

printhead is capped.

2. During transport, make s ure the printhead is capped and
the ink cartridges are installed.

3. If you notice that the printhead is not capped while power
is off, turn power on (in k ca rt ridges should be installed).
After the printhead has moved to the capping position,
turn pow er off again.

4. Ink freezes under 27 °F (-3 °C), but thaws and becomes
usable again after 3 hours at 77 °F (25 °C).

falling edge of this pulse.

The DATA0 through DATA7 signals
represent data bits 0 thr ough 7. Each
signal is at a HIGH level when dat a is
logical 1, and at a LOW level when data
is logical 0.

This signal is a negative pulse indicating
that the printer can agai n accept data.

A HIGH signal indicates that the printer
cannot receive data.

A HIGH signal indicates a paper-out
error.

Always HIGH when the printer is
powered on.

The falling edge of a negati ve pulse or a
LOW signal on this line causes the
printer to initialize . Mini mum 50

A LOW signal indicates a printer error
