Sharp MX-2300 PRINTS BLURY! (Colour Registration Problem)

[Onetouch]

Hi Everyone,
I'm a Canon technician and one of my customer has Sharp MX-2300.
He called me for service and the problem were cyan giving blue line on prints.
I removed the transfer belt and cyan image unit cleaned and put it back in and tested it was okay,
There was no more blue line. But this time I got blurry copies. I can see cyan, magenta and yellow on differently on the colour text where I should be see all one colour. The text it not sharp as it suppose to be.
So, I used to get colour registration problem like this one with canon IRC 3200 all I had to do clean the transfer belt and out it back in if that didn't fix it I would have done DC Clear and it worked every time. But I don't know much about Sharp and I would greatly appreciated if some one can help me out.
Thanks,

Oz

My suggestion is to get yourself a manual.

The color calibration on this model is not simple, and should be done whenever the machine is cleaned and disassembled. =^..^=

I do have the service manual but I'm not sure what section I should look in to.
Do you have any suggestion?
Thanks,

do the complete calibration noted above for the best quality, but u will need a jig and specific test charts to do the full cali.

if ur colors are missalligned u can usually get by with just sim 50-22 and select all.

There is so many things here mention about mis registration problem. It's confusing and it'll take at least half day to do some of these adjustments. One thing I do remember when I tried to open Cyan Drum unit screw I mistakenly opened Cyan image skew adjustment. Is that could be the main reason. I'l try these adjustments and I'll let you all know the result. Thank you so much for your help,
Talk to you tomorrow.

I have tried
Image Skew Adj.
OPC Drum Phase Adj.
Image Density Sensor & Image Registration Sensor Adj.
Auto Colour Registration Adj.
44-2 Colour Image Density Adj. Black image density sensor, Image registration sensor Adj. and I did the Colours as well. I did SIM 50-20/22/28
SIM44-13 Color Image Density Sensor Adj. "FAILED" I have no JIG and I don't even know what it is.
All others were OKAY. What I see the problem is that As you see on the attach file only one side of the paper "Back Side" Cyan is shifting and the rest is okay. It shouldn't be that hard to fix it but i don't know what I'm missing. Only on one side of the paper cyan is shifting. Please see the attachments you may know what I mean. I hope I can get this one go. Thanks,

If you turned the skew adjustment screw by mistake then you will need to do some of the following steps in this guide: Some of these you can make the assumption that they are correct since you didn't mess with them (sim 8, 50-28 and sim 63-3 [you can't do without a SIT chart which are very expensive]) sim 43-13 you can bypass since you don't have the proper jig (there is a work around for this but you probably don't have the means to do it). Most important one that will get you in the ball park is the LSU skew sim 61-4. You will also need some good 11X17 paper for the calibration, it does make a difference (98 brightness is best 92 will work in a pinch).

Good luck.

I finally got it going today, It's still not perfect but it's acceptable for now. Maybe because I don't have JIG or SIT Chart to do all the necessary adjustments. But I'll read manual more and try my best,
Thank you so much for all your help. Your suggestions gave me the courage to do it,
Thanks again everyone,

Replace the primary belt drive gear.
