Docucolor 252 yellow streak

[fatfingers73]

No, can you explain please?

I mainly work on sharp/ricoh, haven't touched Xerox for years.

Seen quite a few of these model recently though. Don't have PWS just service manual.

Any help would be appreciated.

Thank you.

After changing ROS MaxSetup procedure was done ?

You dont need pws because there is builtin service diagnose.
Read in service manual adj9.8 colour registration. It's part of MaxSetup
Same procedure is using in Ricoh copiers and all copiers with transfer belt mechanism.

Hi, thanks for your help.

I can't find the DC Quick menu. Can you help me find it please?

Do you think this could be the reason I still have the yellow band after fitting new ros?

Many thanks.

Adjustment
1. Enter the Diagnostic Mode. Refer to Entering PWS Diagnostic mode.
2. Select dC675 from the DC Quick menu.

You have pdf service manual for DC250 machine which is the previous machine before DC242.
For your machine you have all UI diagnostic service built into mechine
Go to service mode, registration menu and select registration control-setup cycle.
It's a good practice to do registration adjustments after you change ros unit or transfer belt, or...

Thanks, going back there this week to run registration.

Could this be the reason I'm still getting yellow band after replacing ros?

I emailed user, he said they can run 100's off fine then the yellow band returns. After power cycling machine it's all fine again.

Cheers.

May be one of the reason. Yellow marks on IBT are used for corect registration

Hello,

Client said yellow banding has gone, I will still do registration when I go back.

Main problem now are the three marks he's getting on every print/copy. These are 19cm apart.

I tried a different fuser, and all the drums look good, marks are too close together to be transfer belt.

Anyone know the circumference of the black drum?

Thank you.

Anyone, I'm going back on Sunday.

Thanks.

Print every color CMYK at 20% separately and you'll see if it's one of drums.
If it's on every color stop the print before fuser and inspect it. If it's not there that's the fuser problem.
