Kindly help me for the call code?
What is the suspected part and to be done?

The easiest thing to try first is to clean the registration belt sensors, located on the machine's main body, at the left of the transfer belt - pull out the belt assy, and you should see a rectangular metal section with a couple of shutters - the sensors are underneath said shutters.

check the transfer belt it could be walking off the roller. Reset the belt and test.

thats an easy fix, buy a can of compressed air and spray the color registation sensors off, flip 'em up, spray/ then flip em down spray, should take care of that code no problem, happens once a week here.

This was great information. I have followed these steps but after running the Auto Color Registeration Adjustment in 36 mode, I recieve error code 2 - the difference of color registration is to much. How do I go about clearing that error. Any help would be greatly appreciated.
Thanks

Cleaning the sensors is a first start if the problem is too much.

Check to make sure the assembly is level. It likely is, but there is a possibility.

Also, check the belt unit for proper alignment of the rollers. Check the bearings on all the primary rollers, including the tension roller, to ensure they are all ok and inside their respective holders. Any one of these that has popped out can cause problems. Also, check the belt tension levers for proper installation. The side that you take these off to remove the belt from the assembly could be the issue. Also, we have shortened the springs on both sides by a couple coils to increase tension.

Also, another issue found was that the whole assembly was loose, that is, the frame screws to the unit were loose enough that the unit itself could flex while in the machine. Simple to fix..remove the whole unit, remove the belt (as though a PM was being done) and loosen all the frame screws. Lie the unit on a flat surface so the whole unit is square to that surface. Tighten all the screws and reassemble.

It could very well be the registration sensor assembly itself that is at fault. Or there could be a problem with one of the drum units. Though both of these I doubt are the issue, never say never.

Thanks Mike, I'll check these things out

Thanks, Machine is back on but the print quality is very bad. Cyan is blotchy and has lines in it. Black is blotchy. Magenta a yellow seem to be ok. Any Ideas.
Thanks for your help,

How many copies on the box again? Run the toner refresh in the Keyop mode. That should help with the "blotchyness"

Might need a PM on some things. Lines? Are they dark lines? If you do a halftone of each colour (CMYK), do you see darker areas, or white lines? Darker areas most likely is the charge wires, which can be cleaned. Look on the inside area of the toner hopper door, you will see two small little tab like plastic things near the transferbelt stand and jigs. They twist slightly and can be removed. Pull one out and it can be inserted on the bottom side of the charge assembly and rotated in such a way as to allow you to slide it along the charge wire, cleaning oxidation off. Most times this is sufficient. Do another test to see if this improves things or not. Check the counters relating to these as well. If they are at or above 100K, they should be replaced, including the grids. In some cases, wear on the surface of the drum will produce this problem too.

If there are white lines, check for dust in the lazer path. Clean the slit glass for each colour with a clean dry lint free cloth. Use compressed air to clean the path under each developer unit, but do not use full pressure. A light squirt of air through the area is usually enough. Any more than this and you will have a mess that requires you to pull the drum units out and so forth to clean up.

If toner refresh doesn't help with blotchyness, check the count on the developer. If the developer is at or near life (200K), replace the developer. This should be done as a set for all 4 colours at once preferably.

I ran the toner refresh mode and got a SC29-19 error code. Any advice.
Thanks

I'd say leaky dev unit.
