Card Transport Assembly

Activity 1: -- Module Overview / Disassembly

--Have students remove the Card Transport Assembly

• unplug the following sensors from MRB board:

SEN8 card entry, SEN9 card return, SEN10 card exit, SEN

belt home

• loosen the upper 2 screws on the coupler between the lift

stepper and the lift leadscrew

• unplug tab belt motor (at motor end)
• REM assy off of lift guide shaft & anti-rotate shaft

< module rear >

Card Transport Assembly

Activity 1: -- Module Overview / Disassembly

Probable Failure Items

--tabbed belt

--track bias spring

--sensors

--bearings

--leadscrew

card transport assembly

Q. Can tabbed belt be replaced

without removing module?

Without removing assembly?

Q. Is belt installation orientation

important?

Q. Can module continue to run

with a missing tab?

No

No

Yes

Yes

--discuss design of belt

Tabbed Belt Removal

1. loosen (2) screws and

withdraw tensioner pulley

2. loosen tab home sensor for

clearance

3. remove belt from pulleys

4. remove belt

Card Transport Assembly

Activity 1: -- Module Overview / Disassembly

--discuss replacement of

the track bias spring

Q. What would be the affect

of having a weak track bias spring?

Q. What is the proper way to

manually remove cards from the track?

card transport assembly

Track Bias Spring Removal

--withdraw the tensioner

--REM (2) screws that secure

the card track subassembly to

the card transport assembly

upper plate

--REM track bias spring

upper plate

card track subassembly

Index (character spacing) problems or bouncing characters

The spring-loaded upper card guide also provides a means of removing cards manually (see green arrow label)

Card Transport Assembly

Activity 1: -- Module Overview / Disassembly

--discuss replacement of (vertical lift) leadscrew

1. REM card transport

assembly from the

mechanical assy

2. REM (3) screws that

secure the leadscrew

nut to the leadscrew

mounting bracket

3. REM leadscrew

Solenoid Emboss Assemblies

Activity 1: -- Module Overview / Disassembly

--Remove the Front Emboss Solenoid Assembly

• unplug the solenoid from the EMB/TOP

PWA (expansion bd)

• rotate emboss wheel so unused portion

is in front of driver assembly

• REM the two screws that secure

the solenoid assembly to the front

vertical support plate (heavy

assembly)

• REM the solenoid assembly

along with any associated shims

vertical support plate

Q. What is the purpose

of the shims?

Q. If the solenoid is

being replaced, are

the same shims

used?

For character height adjustment of broad range of characters

Must evaluate character height to determine number needed

PROCEDURE:

Solenoid Emboss Assemblies

Activity 1: -- Module Overview / Disassembly

Probable Failure Items

--driver

--internal thermal cutoff switch

assembly

solenoid shim

dampening washer

driver

(3) cupped washers

--Remove the Driver Assembly

• REM solenoid assembly
• REM single mounting screw along with

(3) cupped washers

• REM driver & shaft (assembly)
• REM dampening washer and shim from shaft

Concave side must face plunger

face

Driver face must be straight up and down so it aligns with punch or die in wheel

PROCEDURE:

Q. Upon re-installation, how are

(3) washers oriented?

Q. Upon re-installation, what

precaution must be taken when

tightening the mount screw?

Emboss Wheel Assemblies

Activity 1: -- Module Overview / Disassembly

Step 3

--Remove the emboss wheel assembly

wheel washer

spring

1. REM mechanical assembly from module

2. Rotate wheel so unused section is in front of

drivers

3. REM the wheel washer and screw from the front

side of module

4. REM (4) mounting screws and slide back front

vertical support plate

5. REM emboss wheel and spring

support plate

PROCEDURE:

Step 4

Step 5

Emboss Wheel Assemblies

Activity 1: -- Module Overview / Disassembly

Probable Failure Items

--punches & dies

--spring

--band

P/D slot

return spring

wheel cap channel

--perform punch & die removal

using training prop

• loosen wheel band
• position band slot over the character
• slide character out of wheel

--discuss wheel band

adjustment

Warning :

Anytime characters have been replaced, test cards should be run to verify embossed information is correct and quality is acceptable.
