(Figure 2-5).

Remove the old roll from the mandrel. Slide the new roll
of paper onto the mandrel. Replace the paper roll
retainer previously removed.

Reinstall the mandrel on the roll paper holder assembly
so the paper feeds from the bottom of the roll (Figure

Position the paper roll to the left of the holder (as
seen from the front). Make sure the paper roll retainers
are touching the paper roll to prevent it from moving
from side to side. Do not let the paper roll retainers
touch the side of the roll paper holder. That creates
unnecessary friction.

Feed the paper over the roll holder apron and under the
platen from the back. Lift the bail bar and advance the

paper, using the paper advance knob, until the top edge
extends back over the apron (Figure 2-6). Make sure the
paper does not pass under the paper low sensor (Figure

OPERATOR SELECTABLE FEATURES

The Letterprinter 10¢ has many operator selectable features. Some
features such as the operator control
panel,
and the printer
controls are described in other chapters. This chapter describes
the switch selectable features and the auto answerback features.

computer.

To locate the switches, open the access cover and move the
printhead to the right side plate. Figure 3-1 shows the location
of the communication switches and the 1labeled function of each
switch. There are three different switches used in the terminals;
two types of rocker switches and one slide switch (Figure 3-2). It
is important to identify which type switch your terminal has
before trying to change any of the communication features.

To select a feature using a rocker switch, press the side of the

switch that corresponds to the desired selection. To select a
feature using a slide switch, push the switch tab to the side that
corresponds to the desired selection.

CAUTION: Always use a small blade screwdriver, ball point pen, or

equivalent to change a commuhication feature. Never use a lead
pencill.

restraint mode. The restraint feature prevents the loss of
received characters. When restraint is on, the terminal controls
the BUSY EIA control line to indicate when the input buffer is
almost full or empty. The BUSY line turns off indicating a full
buffer and requests the computer to stop sending characters. The
BUSY line turns on indicating the buffer is nearly empty and
requests the computer to continue sending characters.

The speed control feature exchanges speed control information
between the terminal and the modem. The SPDI and SPDS EIA control
lines are used. Set switch 1 to the right to select restraint and
to the left to select speed control.

Modem Control Switch 2 -- controls the EIA control lines used to
communicate with the computer. The actual lines each feature uses
are described in the Programmer's Reference Manual. Set switch 2

to the right to select no modem control and to the left to select

modem control.

Do not place drinks and metal objects on any part of the terminal.
There are several openings in the covers that 1liquids or small
objects can fall through. Such objects disturb the electronic
operation of the printer if they come into contact with the
circuitry.

Do not block the ventilation slots on the top and bottom
printer. Blocking these slots overheats the printer.
