Status Indicator RAPs
11K-171 HVF Initialization Failure RAP
When an initialization command is received from the machine, the HCF polls all of the relevant
sensors to check if the various HCF modules are in their home positions. If any sensor reports
that a module is not in the home position, the HCF attempts to drive that module to the home
position. If unsuccessful, a fault status is raised and that module is disabled. If all modules are
reported in their home position, the HVF is initialized with the following actions:
1. Bin 1 lowers then raises.
2. The ejector assembly paddle performs two revolutions.
3. The curl suppression solenoid energises and raises the paddle module’s centre flap.
4. The paddle module moves to the up position.
5. The paper pusher moves to the down position.
6. The ejector assembly travels to the out position.
7. The curl suppression solenoid de-energises and the paddle module’s centre flap drops
down.
8. The stapler module travels to the inboard position.
9. The stapler module returns to the outboard position
10. The curl suppression solenoid energises and raises the paddle module’s centre flap.
11. The paper pusher moves to the up position.
12. The ejector assembly returns to the home position.
13. The support finger motor turns on and drives the support fingers to the initialisation posi-
tion, which in turn pushes the pressing plate fingers down onto bin 1.
14. The support finger motor reverses and drives the support fingers to the home position,
which in turn retracts the pressing plate fingers.
15. The the front tamper moves to the away position then moves to the home position.
16. The bin 1 offset motor turns on and moves the ejector assembly, front taper and rear
tamper to the away position and then to the home position.
17. The paddle module moves to the down position.
18. The entry feed motor 1, bypass feed motor, buffer feed motor and the exit feed motor 2
turn on.
19. The booklet maker diverter solenoid actuates, if applicable.
20. The exit diverter solenoid actuates.
21. The booklet maker diverter solenoid de-actuates, if applicable.
22. The exit diverter solenoid de-actuates.
23. The hole punch unit motor and hole punch head motor turn on momentarily, if applicable.
24. The entry feed motor 1, bypass feed motor, buffer feed motor and the exit feed motor 2
turn off.
NOTE: The HVF initialization procedure can be triggered by opening and closing the HVF front
door, or by raising and lowering the top tray. When this is done the tray will not lower com-
pletely, but will adjust its position.
The booklet maker is initialized as follows:
1. The BM tampers are driven to their home position, unless already home.
2. The BM backstop is driven to the home position, unless already home
3. The BM crease roll gate is driven to the home position, unless already home
4. The BM crease blade is driven to the home position, unless already home
5. The BM staple heads are driven to their home position, unless already home.
Initial Actions
WARNING
Ensure that the electricity to the machine is switched off while performing tasks that do
not need electricity. Refer to
GP 14 . Disconnect the power cord. Electricity can cause
death or injury. Moving parts can cause injury.
Open the HVF front door. Cheat the front door interlock switch. Fully pull out the BM module
