Printing is synchronizing

Hi

Dear this problem for wrong driver, please install the correct driver for windows 7, printer is not synchronize with your printer, download the driver for click hear
and select you correct printer model and select the Windows 7(32bit) and download, after downloading uninstall the old driver and install new driver, and check again..

Re-install the printer ribbon. It's probably slipping or dragging on the head mechanism, and the printer synchronization control is slowing everything down to compensate.

Printing shows blurry printed image.
Possible Cause:
•Ribbon cartridge may not be correctly positioned.
Solution:
•Check that the ribbon is properly rolled onto the ribbon cores of the cartridge, with no wrinkles.
•Replace ribbon cartridge, making sure it locks in place, and print again.
Possible Cause:
•Ribbon may not be synchronized on the correct color panel position.
Solution:
•Open lid, then close lid to synchronize ribbon.
Possible Cause:
•Cards may not meet specifications.
Solution:
•Use a different supply of cards.
Possible Cause:
•Dust or embedded contamination inside the printer and/or dirty Cleaning Roller.
Solution:
•Clean the Print Head.
•Replace Cleaning Roller

Laser synchronization error

Symptom:
The main scan synchronization detector
board cannot detect the laser
synchronization signal for more than 10
consecutive 50 ms intervals.

Possible Cause:
• Poor connection between the laser
synchronization detector board and
the SBCU board
• Laser synchronization detector board
out of position
• Laser synchronization detector board
defective
• SBCU board defective
• LD unit defective

Brother printer error code 7a occurs when the main motor fails to synchronize properly with the reference clock.

Hello sir; Sometime this problem can be reset, just let's try, ; Press " clear mode ", "107", "stop/clear" key until screen show out sp mode then turn power off and back on again.

Main scan length detection is

The front (for C&M) or rear (for
K&Y) laser synchronizing
detector boards are used for
the main scan length
detection, which automatically
corrects the main-scan

• Damaged or
disconnected cable
between front (C&M)
or rear (K&Y) laser
synchronizing
detector board and
the LD unit
• Incorrect installation
of front (C&M) or rear

detector board (the
beam does not target
the photo detector.)
• Defective front (C&M)
or rear (K&Y)
synchronizing
detector board
• Defective LD unit
After doing any of the following, print ten
jobs or more to see if the same SC code
is displayed:
1. Turn the main switch off and on.
2. Check or replace the cable
connecting front (for C&M) or rear (for
K&Y) synchronizing detector board
and the LD unit.
3. Check or reinstall the front (for C&M)
or rear (for K&Y) synchronizing
detector board.
4. Replace the front (for C&M) or rear
(for K&Y) synchronizing detector
board.
5. Replace the laser optics housing unit.
6. Replace the BCU.
If a synch. detector board cannot be
replaced, do the following as a
temporary measure:
• Disable main scan length detection

1st Laser synchronization error signal error. The 1st Laser that turns on inside of the printer can't synchronize properly to print out documents which is why this message comes up and nothing is printing. Probably is going to need to be replaced but a qualified service tech is going to need to look at it further.

Another poblem with this machine is that the sync detect for the 400 dpi and 600 dpi could be off. Go into service modes by pressing the yellow clear modes key then pressing the numbers 1 0 7 then hold done the red stop key till you see the display change. Now go into copy sp, then hit the 2 in the window {drum}, next use the page down button located in the middle of the screen till you see the one that says 2109 LD Beam Pitch Adjust. Go to number 2109-8 beam pitch data reset. execute then go to 2109-1 and set it to 144 then hit pound. Now go to 2109-3 and execute. last go to 2109-2 and set it to 168 then hit pound. Now go to 2109-4 and execute. exit out of the service modes window. now try to run a copy and a print. If these fail the you either need to clean the laser assembly, a polygonnal mirror moror or laser drive unit.

The printhead was installed in another machine and the codes do not match. You need to manually sync them. Here is the procedure:

Manually synchronize the Printhead and Electronics Module codes.
NOTE: The Printhead and Electronics Module codes should synchronize automatically when a new printhead is installed. If a 19,004.40 error occurs, it is possible that the replacement printhead was previously installed in a different printer. After manually synchronizing the Printhead and Electronics Module codes, be sure to test the new printhead for print quality defects.
To manually synchronize the codes;
1). Power OFF the printer.
2). Disconnect the printer from external devices (A/C power can remain connected).
3). Locate the "Factory Only" port on the electronics module (located between the PS and PE lights (Figure 1).
4). Use a Hard Disk Drive (HDD) jumper (Figure 2) to short the top two pins.
NOTE - If a HDD jumper is not available, use another conductive item, such as a screwdriver, to short the pins. Use caution to avoid contacting the surrounding frame, as this may permanently damage the Electronics Module.
5). With pins shorted, power ON the printer.
6). When printer reaches the mechanical initialization stage of the power on sequence, power the machine back OFF.
7). Remove the HDD jumper.
8). Code should now be synchronized. Power ON machine and verify the 19,004.40 error does not re-occur.
NOTE - If error persists after this procedure, attempt the procedure again, and be sure to allow the printer to complete its BIST and POST test before powering OFF in step 6.
