Acroprint 200, Service And Parts Manual

The Cancellation Microswitch and the Print Microswitch are
wired in series. Both Microswitches must close before a print
can be made. Once a print has been made and the time card is
still in the Card Receiver, the blade on the Cancellation
Microswitch will be under the step in Cancellation Pawl. The
time card must be pulled up far enough so that the bottom
edge of the time card will allow the Right Hand Operating
Lever to restore to a normal position with the Cancellation
Microswitch. Now the recorder is ready to make another print.

The Cancellation Microswitch should close each time a time
card is inserted; also, when there is not a time card in the
Receiver, the Cancellation Pawl should be free to latch with
the blade on the Cancellation Microswitch. Both of these
adjustments are made by forming the blade on the Cancella-
tion Microswitch.

The Card Trip Lever has an extension on the back side which
fits into the Punch and Die. This extension is what the time
card presses when closing the Print Microswitch. As the Print
Microswitch closes, the blade will stop on the Print
Microswitch Limit Screw which is located in the Left Side
Frame. The Limit Screw can be adjusted for various printing
spacing on the time card. The further the time card goes into
the Die before printing, the further apart the distance between
each print will be on the time card. Likewise, the shorter the
distance that the time card travels into the Die the least
distance between each print. To test for proper adjustment, set
recorder to PM hours, especially on the models that use 1-12,
1-12 hours, and make certain that the underscore does not
print over the previous registration. Turn the Limit Screw in
for less spacing and out for more spacing. It may be necessary
at times to form the blade on the Print Microswitch for the
spacing you need, if proper spacing cannot be obtained by
adjusting the Limit Screw.

As the time card is punched it will go deeper into the Card
Receiver. To eliminate any excess side clearance that might
develop as time card goes deeper into the Card Receiver, there
is a Lower Card Margin mounted under the Punch and Die.
The Lower Card Margin is adjusted to keep the time card
straight as the time card goes through the Punch and Die. To
test for this adjustment, print half of the time card, unplug
recorder and insert the time card. With time card touching the
Right Card Guide, the left side of time card should clear the
Lower Card Margin, about one-sixteenth (1/16") of an inch.
Loosen the Mounting Screws in Lower Card Margin and move
Lower Card Margin left or right for the correct clearance, and
then tighten Mounting Screws. Insufficient clearance between
the time card and the lower Card Margin will cause the time
card to fit too tightly and roll the left side of time card. Too
much clearance will cause the printing to be out of alignment
and affect the spacing between prints.

VI. RIBBON DRIVE & REVERSE

Every time the Model 200 prints, the Hammer Shaft pulls the
Ribbon Feed Lever down. The Ribbon Feed Lever should be
adjusted by the two Set Screws so the Ribbon Feed Pawl will
advance the Ribbon Ratchet 2 teeth. Attached to the Ribbon
Feed Lever is the Ribbon Feed Pawl. The Ribbon Feed Pawl
will engage with the Ribbon Feed Ratchet and rotate the
Ribbon Feed Ratchet 2 teeth every print. The Ribbon Reverse
Shaft  is driven by the Ribbon Feed Ratchet. There are two
Gears on the Ribbon Reverse Shaft that drives the Ribbon
Spool Shaft. Adjust the Ribbon Reverse Shaft by aligning it
flush with the hub on the Ribbon Feed Ratchet and tighten the
two Set Screws in the Ribbon Feed Ratchet. Push the Ribbon
Feed against the Left Side Frame, the Left Side Frame is the
stop for the Ribbon Reverse while driving the Right Ribbon
Spool Shaft. Then adjust the right Ribbon Drive Gear to mesh
with gear on the right Ribbon Spool Shaft. Do not mesh these
gears too tightly as this will cause a bind. The Ribbon Drive
Gear on the right Ribbon Spool Shaft can be adjusted up or
down for proper gear mesh. Now that the Ribbon Drive Gear
is in proper mesh, tighten the Set Screw in the right Ribbon
Drive Gear. While the Ribbon Reverse Shaft is in this position
(driving the right Ribbon Spool Shaft) space the Ribbon
Reverse Shaft Collar 1/8" from the Left Side Frame and
tighten the Set Screw in the Collar. This Collar will be the stop
on the Ribbon Reverse Shaft while driving the left Ribbon
Spool Shaft. Push the Collar against the Left Side Frame, slide
the left Ribbon Drive Gear into proper mesh with left Ribbon
Spool Gear and tighten the Set Screws. Adjust the Gear on the
left Ribbon Spool up or down for proper gear mesh.

When the Ribbon Reverse Levers are to the left, the Ribbon is
winding on the Right Spool. The Ribbon Reverse Levers are
held in this position by a Stud in the Ribbon Reverse Bracket
and toggle Pawl on the Ribbon Reverse Lever Assembly.
Adjust Ribbon Reverse Flange left or right so that Stud in the
Ribbon Reverse Bracket is equal distance on each side of the
Toggle Pawl. This adjustment can be checked by manually
moving the Ribbon Reverse Levers left and right noticing the
Stud position to the Toggle Pawl.

On each Ribbon Spool Shaft is a Ribbon Shaft Tension Spring
and Collar. The purpose of this Spring is to put tension on the
Ribbon Shaft so that the Drive Gear will mesh, and the Ribbon
Spool will not unwind too freely, but will turn easily. Too
much tension will impede Ribbon Drive and printing. Too
little tension may cause the Ribbon to twist if the Ribbon
unwinds too freely.

Near each end of the Ribbon is a Reversing Rivet. As  the
Ribbon moves through the Ribbon Reverse Levers, the
Reversing Rivet pushes the Ribbon Lever and moves the
Levers in the direction the Ribbon is traveling. At the same
time, the Stud in the Ribbon Reverse Bracket moves to the
other side of the Toggle Pawl which moves the Ribbon
