Reg issue in the sub scanning direction in IRC 5180

[digitalbrain]

I am attaching PG-6 test print

This machine has done 500k pages. 90% on 100gsm paper 10% on 256gsm. First we had a complaint that reg problem when doing multiple prints on 256gsm glossy . No problem when taking single copy at a time.

All Drum units life show over 250. But prints are coming good.

Now this problem has become acute and occurs on 100gsm paper also.

I have swapped Transfer belt assembly with another good one, Manually resetted all the Laser assemblies, Cleared DC-CON and put in the machine default values from the machine label. Still the problem continues..

can anyone please tell me how to solve this issue

Thanks in advance

COPIER>FUNCTION>LASER>LD-ADJ-Y/M/C
Making the tilt correction motor return to the initial
position automatically.
Operating Instructions
1) Select this mode.
2) Press the OK key.
- The operation starts. It automatically stops when it is completed.
Reference:
The tilt correction motor may get locked when the tilt amount in the horizontal scanning direction exceeds the expected range, and consequently color displacement cannot be corrected even though automatic registration is conducted.
When this symptom occurs, use this mode to make the tilt correction motor return to the center position
automatically.
(If you try to do this operation manually by opening the scanner unit, you may touch the lens. For this reason, be sure to do it by the automatic operation.)
This Service Mode is used to correct the tilt of Y, M, and C against BK, which is used as a reference, when the tilt is
large (when the horizontal lines are higher at the right).


In service mode (Level2) > COPIER > Option > BODY > CLR-SHFT, check the setting value; if it is '0' (OFF),change to '1' (ON) and then make copies again.
- CLR-SHFT: As the method for improving color displacement occurring with heavy paper, if this mode is set to '1', this machine will change its operation so that it will starts the next operation after the previous paper comes out of the secondary transfer roller.
Reference: Negative effect caused by setting this mode to '1': The productivity for heavy paper will be decreased to one-thirds.



may be time to replace the Drum Drive Assembly (FM2-5360-000).

also this gear unit needs to be checked for worn/damaged teeth/ a known issue of dual reg. issues

Thanks for the reply Teckat

The reg problem in crossfeed was not present before I resetted DC-CON. may be it is due to some improper value which i have to check or i may have do laser adjustment again. I have set CLR-SHFT to 1 before when this problem was present only in 256 gsm glossy.

I have now done RAM Clear in *1734* mode and input label values but the problem remains

Can this be a DC Con PCB 1 or 2 issue ??

what is a *1734* mode ?

when u have a printer like the 5180 or 3200 that is printing mainly heavy stock it puts a burden on the Drum drive motor , this clock pulse motor craps out and causes weird issues. It is a pain to replace.

Did u inspect/replace the Secondary Transfer Roller unit/ and ITB Cleaning Blade ??

Go in and pull out the Pattern Reader Unit
remove cover /check that auto registration sensor PCB/ & SALT Sensor inside

u can try an MN-CON CLEAR/ remember to put back settings/
make sure to print out a P-PRINT, and User Data Print before clear

post a PG10

sorry it is *1739* factory settings mode

[V-P]

never heard of this factory setting mode - *1739*

I just tried this combination : 3 pages with numbers which I don't know the meaning came up.

Who knows their meaning ?

Has this issue been corrected with the latest system software so you don't need to do it manually any more?

Its that way for a reason its not designed to be used by techs and as end users read this forum them either.

[New] Addition of Service mode which clears the auto-registration detection
correction values
- When the correction value adjusted by auto-registration detection becomes an
incorrect value, this Service mode can clear the correction value and set it to default.
* This setting is enabled when combining with DCON v53.02 or later.

Service mode (Level2) > COPIER > FUNCTION > CLEAR > REG-CLR

firmware is now v93.01.01

I have checked DC-CON is 60.02 MN-CONT is 21.01. There is no REG-CLR in CLEAR (Level 1 & 2)

I have removed the Patern reader unit cleaned and fitted back.
The problem persists. I rectified shift in main scanning by setting the correct LDADJ values (given on the Laser unit). The shift in sub scanning is not solved.

I am not having latest firmware to update (I am having SST installed). Is it possible to get it downloaded ?

Thank you very much for your replies

if u do not see Reg-CLR in Level2/ u need to go in the SST AND RELOAD your Firmware

Service mode (Level2) > COPIER > FUNCTION > CLEAR > REG-CLR
came out in System Software (MN-CONT) v65.17-10/2007

Your Firmware is not loaded correctly /

v60.02 DC-CON ,I believe was in released in System Software (MN-CONT)v84.01,in 7/2008-
your System Software (MN-CONT) v21.01 is old and mismatched with DC-CON ver.
also your System Software ver.(MN-CONT) and Language ver. must match-

who loaded this DC-CON v60.02 and did not update the rest of the firmware ?????

Actually this is a refurbished unit and being used as it is for the past 6 months without any problem (only the slight reg problem when using heavy stock) . I dont have any system software for this model so I have not loaded any . Is it possible to buy System Software online ??
