The spinner assembly (sheet 1, #202) rotates the penta prism
which reflects the laser beam to the surface of the drum.
Before You Start Tools & Accessories Disassembling
the Spinner Assembly Assembling
the New Spinner Assembly Test
Before You Start
Prepare a clean surface with a lint free cloth.
Be sure that you have enough free space in and around the
machine to pull the assembly out.
Never touch the set of screws that balances the spinner
movement.
Identify the fiber optic path. Be careful when working with
the fiber. Do not bend, crush or stretch it.
The replacement requires good lighting. Set up a light stand
or some other method of providing sufficient lighting.
Tools &
Accessories
Set of Allen keys
Spinner centering jig (507C1L231)
Bow Adjustment Jig (280B34187)
This device is attached to the spinner. Its three dial
indicators (cat no. 395B10020) allow you to center the newly placed spinner in the same
position as the previous spinner.adjustment plate jig . (cat no.
280B33336)
Disassembling
the Spinner Assembly
Open the left and right service doors.
Remove the light-proof cover from both sides of the unit.
Enter the diagnostics utility and move the Film Feeder roller
to the middle of the drum circumference (400-600 mm).
Send the carriage to end position. (To the right).
Remove the shutter protector (#225)
Release four (4) of the five crews that hold the spinner
assembly to the carriage (#205).
Run the diagnostics and return the carriage to Home position.
Power off the imagesetter using the control panel ON/OFF
switch.
Release the shutter cable and the fiber optic cable from the
clamps (Nos. 206, 207, 208).
Disconnect the spinner connector. Open the encoder cover (#29)
and disconnect the internal connector. Refer to bottom right of figure:
Release the remaining screw that holds the spinner housing
assembly. This can be referred to as the "positioning screw."
Carefully pull out the assembly and put it on a clean surface.
Assembling
the New Spinner Assembly
Put the spinner assembly carefully into place. Pay attention
to the focus lens. Do not scratch it.
Assemble the five screws of the spinner housing assembly, but
do not tighten them.
Re-connect the spinner connector, encoder connector and the
wiring. Secure them.
Close the encoder cover.
Adjust the new assembly. Refer to Adjustment .
Test
To check if the bow linearity and focus is within the
specification, expose and measure a grid file .
If the results are not within the specification, perform the
bow, linearity and focus adjustment procedures.
Take the Spinner Centering Kit (280B34190) with the three dial
indicators. Put it on the reference jig and adjust the zero points if necessary.
Attach the jig to the spinner housing assembly (be careful
with the wiring and the fiber optic cable).
Assemble the lower adjustment plate to the lower part of the
spinner assembly holder.
Screw on the plate until it nearly makes contact with the four
adjustment screws.
Loosely assemble the fifth screw of the spinner assembly, but
not too much (enough to keep the assembly in place).
Screw in the adjustment screws to move the spinner housing
assembly to a centricity. The tolerance should be within +/- 20 micron.
Tighten the five spinner housing screws and remove adjustment
screws.
Dismantle the Spinner Centering Kit.
Expose a Grid File and measure it. If the Bow error is greater
than 30 microns then Perform the Bow Adjustment Procedure.
Measure the Grid and if the Linearity error is greater than 50 microns then
perform the Linearity
