Take them out of the circuit. Put an ohm meter across the leads, the meter should swing all the way over then slowly go back to zero. If the meter doesn move, the cap is open, if it goes all the way over and doesnt return it is shorted.

How can i repair str z2062 power supply of my hp m1005 mfp laser printer ?


First of all; it is DANGEROUS to fix a power supply if you don't know what you are doing. Thus; don't even think about to open power supply tower, if you are not qualified enough.

If you are a qualified person, you can go on with below steps by taking risk on your own.

You must discharge biggest capacitors in order to avoid any fatal electrical shock. Even it is disconnected from electricity plug, power supply may keep high voltage in it for long time. Once you discharge big capacitors; you may diassemble power supply tower. At your question you mentioned about burned power supply which makes it a little bit easier. (I assume you discharged big capacitors) Once you open psu tower; do visual inspection on each capacitor. If there is a burned area start with it. Remove blowed capacitors and replace them with same valued new capacitors. If you can't see the values on blowed capacitors; you need to find board diagram of your psu. Otherwise you can't find suitable one to replace. Besides; check form of other capacitors. If there is a change on any capacitor's form, replace them too. The best way to find out dead capacitors is using capacitor testers. If problem caused by another type item; its not easy to find it as finding bad capacitors.

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",
"192", "240").

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
dpi).

.

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.

My colors are printing separately, divided and do not overlap or blend. I use a Roland 540 printer, and I have replaced chips, motherboard, and encoder sheet. What would cause this?


If a gap is present decrease the value by going to Menu, Calibration, Setting and pressing the Down Arrow to decrease the percentage shown to match what setting is best on the test pattern. Press Enter to save the value. If the printer does not show multiple test patterns perform the Feed Calibration, Test Print again to check the results.
If an overlap is present increase the value by going to Menu, Calibration, Setting and pressing the Up Arrow to increase the percentage shown to match what setting is best on the test pattern. Press Enter to save the value. If the printer does not show multiple test patterns perform the Feed Calibration, Test Print again to check the results.
Tech Tip: The Feed Calibration is a very fine adjustment meaning that an incremental adjustment of .05% or 10% is very small. Some media will require an adjustment in much larger steps.
Note: The Feed Calibration setting on the printer will be overridden by Versaworks as a default. This can lead to a very confusing scenario where the Feed Calibration setting doesn't appear to make any adjustment. Please see the next page for information on setting the Feed Calibration in Versaworks.

Once the proper Feed Calibration has been established on the printer it is important to make sure this setting is correct in Versaworks. Once Versaworks is open and a job has been loaded, perform the following steps:
A. Double click on the print job to bring up the Job Settings window and set up your media size, copies and other relevant items under Layout.
B. Select the Quality tab and Select the proper Media Type for the job. This step is critical because the Feed Calibration is tied to the type of media being used. When the Media Type is changed the Feed Calibration setting will change to the setting which is default for the Media Type.
C. Next select the Printer Controls tab on the left hand side and under Feed Calibration Controls choose Use Printer Setting.
D. Select OK to save the settings.
Tech Tip: In step C you can also select Use Custom Settings and enter in a value for the Feed Calibration. This allows for making corrections to the Feed Calibration without changing the settings manually on the printer. If you choose Use Default Media Settings or Use Custom Settings the value that has been set on the printer will always be overridden.
Tech Tip: In addition to having multiple test patterns which make for a quick and easy selection to be made the RS, XJ & AJ printer models allow adjustment of the Feed Calibration mid-print by taking the following steps:
A. Press the Menu key
B. Scroll to Calibration, Setting and pressing the Down Arrow to decrease the percentage shown or Press the Up Arrow to increase the value.
C. Press Enter to save the change in value.

apparently the default printing color has been changed, you have to change it back either from "control panel/ printers /right click on your printer and click properties, and choose color for printing." or you can do it per printing job, when it shows u the printing options, (like number of copies and other (basically same window from the control panel). if you do it from the control panel whatever you choose, that would be the default, otherwise it is per job change and is not permanent.

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”,
“192”, “240”).

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
dpi).

.

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.
