Open the side cover, and unlatch the plate. The PCUs are located in there. In the replacement PCU, there should be instructions.

SC 329: Laser Beam Pitch Adjustment Error
The LD unit home position sensor does not detect an on condition while changing the LD unit position for correcting the LD position or changing the DPI.
Instructions from the Service Manual below...
5.4.3 LASER BEAM PITCH ADJUSTMENT
There are two laser beam pitch adjustment procedures: one for 400 dpi, and one
for 600 dpi. These adjustments use the following SP modes.
· SP2-109-1: Laser Beam Pitch Adjustment – 400 dpi
· SP2-109-2: Laser Beam Pitch Adjustment – 600 dpi
· SP2-109-3: Laser Beam Pitch Initial Setting – 400 dpi
· SP2-109-4: Laser Beam Pitch Initial Setting – 600 dpi
· SP2-902-2, no.12: IPU Test Pattern – Cross Stitch – 400 dpi
· SP2-902-2, no.13: IPU Test Pattern – Cross Stitch – 600 dpi
1. Perform SP2-109-8 (Beam Pitch Data Reset).
2. Input the value for 400 dpi that is printed on the LD unit into SP2-109-1.
Use the value printed after “P” on the new LD unit as shown below.
NOTE: Do not use values printed after a “V”.
(These value numbers are on a sticker inside the machine with a UPC code on it. The numbers are just under the UPC barcode. And example number looks like this: "15980300151P: 120, 172", so the example 400 dpi value here is "120".)
3. Press the “Enter” key.
4. Perform SP2-109-3.
5. Print the 400-dpi test pattern onto A3 (11”x17”) paper using SP2-902-2 no.12
(cross stitch). (See Service Tables - Test Pattern Printing - Section 4.2.3, pasted below.)
6. Write the value of SP2-109-1 on the test pattern which was input at step 2.
7. Change the value of SP2-109-1 and print another test pattern, repeating steps
2 to 5. Print about 5 patterns with different values for SP2-109-1 (e.g. “48”, “96”,
8. Check this test pattern. If the laser beam pitch is not correct, the image looks
like a black vertical stripe pattern.
NOTE: If the laser beam pitch is correct, the vertical stripe is not so noticeable.
If the value is not correct, the vertical stripe pattern is darker.
9. Adjust the laser beam pitch position until the thin lines are of uniform thickness
(no striping effect should appear on the printout), doing steps 2, 3, and 4. (In
step 2, input a value which is estimated to be correct, then do steps 3 and 4,
then if necessary go back to step 2 and try another value.)
10. After adjusting the laser beam pitch for 400 dpi, adjust the laser beam pitch for
600 dpi, using the same procedure as for 400 dpi (use the SP modes for 600
4.2.3 TEST PATTERN PRINTING (SP2-902)
NOTE: Do not operate the machine until the test pattern is printed out completely.
Otherwise, an SC may occur.
1. Access the SP mode which contains the test pattern you need.
2. Press exit, then touch the “Copy Mode” key on the operation panel to access
the copy mode display.
3. Select the paper size.
4. Press the “Start” key to print the test pattern.
5. After checking the test pattern, exit copy mode by touching the “SP Mode” key.
Reset the test pattern to 0.
6. Exit the SP mode.

These adjusments listed in the manual require removal of a service panel and mechanical adjustment of the laser mounts, so it should be done by a qualified technician.
However, these test procedures can indicate whether or not this is the problem with your printer.

This is a fuser temp. problem -- must reset and/ or replace thermistors.
Press clear modes button then 1-0-7 then hold down the clear stop button.
When display changes touch copy sp modes.
Turn may power off and wait about 30 sec.
Turn power on.
If the machine comes to ready you are ok for now.
If code returns you must replace thermistors.
If you need to replace thermistors, contact me and I will get you part numbers and instructions.

It is a scanner problem....could be lamp, lens defect, or as simple as the lamp, and lirrors undeer the glass being very dirty, because the code refers to the 'white level"....a calibration that the machine does when switched on. It could be as simple as, the white plate which is underneath the left scale (beside the main contact glass) is dirty (or missing). Try cleaning this (2 screws), and while you're at it, try removing the main contact glass (3 more screws)and cleaning it as well as the scanner bulb, and mirrors (slide scanner to the right with the machine unplugged).

Error code sc 547 means "Zero cross signal malfunction". This error appears due to a faulty power supply. This error code may also appear if the input board is defective or the BIC Unit is defective. Turn off the printer and unplug the printer for 30-40 minutes and check if the error still appears. If you see he error still appearing then try and rest it using the following reset method--
To reset the SC code by entering SP5810 and select 1.
Now hold down the photo mode key and the # key at the same time for at least 3 second.
Then turn the machine off and on again.
If the same issue still appears, you'll need to check and replace the Power supply or the Input (IOCC) boardt.
Hope it helps...
