These levers (see Figure 2-2)permit the operator to unlatch and
open the belt unit. An unlatched condition (error code 06)is
notified by a switch.
To remove the ribbon cassette, this lock (see Figure 2-2) must be
set parallel to the opening in the cassette.
This lever (see Figure 2-2) permits the operator to release the
print belt for removal or to tighten the print belt during installa-
tion. The ribbon cassette must be removed to gain access to the
lever.
When no paper is present between this bar (see Figure 2-2) and
the paper entry guide, an end of paper condition (error code 05)
is notified.
Loosening the tractor locks (see Figure 2-2) allows the operator
to move the tractors horizontally in order to change the form
width.
This knob (see Figure 2-2) allows the operator to move the paper
manually through the printer for line adjustment. The tractor
clutch switch (see Figure 2-4) must be in the declutched position.
This screw (see Figure 2-2) permi ts the operator to adjust the
paper horizontally with the tractors locked. This device is pro-
vided as an option.
The line indicator (see Figure 2-3), used together with the line
adjustment knob, permits the operator to position the first line
to be printed.
The column indicator (see Figure 2-3) permits the operator to
position the first column to be printed by moving both tractors
horizontally or using the horizontal fine adjustment.
This control (see Figure 2-4 ) regulates the force of the print
hammers. The setting depends on the number of copies to be
printed. The control must be set such that proper print quality is
obtained with the lowest possible hammer force.
This switch (see Figure 2-4 ) controls the instant of hammer fir-
ing. The switch must be set to give equal print density on both
sides of the characters.
This switch (see Figure 2-4) permits the operator to disengage
the tractor drive shaft in order to move the paper manually
through the machine.
