5035 Magenta color blur

[Kripp]

Hello

We have a problem with one 5035 machine and we are running out of ideas what might cause the problem. The magenta color is sort of blurred like in the picture attached.

New drum, new developing assembly and new TR Belt. The next thing might be to replace the laser, we removed the laser and cleaned it though. But before that I wanted to post here since I find solutions here all the time.

Did u print out a GRID TEST PRINT ?? PG6
or a test print TYPE 10

Make sure nothing is preventing Drum from seating properly

Perform a REG CLR in service mode level 2: Copier > Function > Clear > REG-CLR.


CAUTION:
- When removing the Laser Scanner Unit, be sure to check the serial numbers affixed on both units and installation position of the units before operation.
- Before installing the units, be sure to see the forgoing serial numbers and install each unit to the original position. It the unit is installed reversely, the image displacement might occur.
- DO NOT disassemble the Laser Scanner Unit.
- At installation, push the protrusion of Laser Scanner Unit into the hole of rear plate and adjust the front boss with the plate hole and install it.

Yeah I tried doing the grid test and every color is aligned just fine, one funny thing is that the lines are almost green. Compared the page with another one from another machine and those lines where all black and from this one more darkgreen lines. And with PG type 10 you can see blur on the top and bottom end of the magenta lines, Iam not at work at the moment but I could scan and upload those tomorrow. One thing to notice is that the magenta line with PG10 on this machine is more pink than red.

Will try the REG CLR tomorrow and report back! Thanks for the reply though.

Hello again!

Tried the reg clear today but the problem still is there, this is how the PG10 looks like (Dont mind the white lines between but notice how the magenta color is darker at the top and brighter at the bottom). And the "blur" on top of the magenta lines.

Will try to swap the laser unit today with another one.

Looks like you have a registration problem on both axis. Try to fix that.

Did you replace the ITB Cleaner ?

Yeah I think the laser is not really aligned or in position. But I am gonna swap lasers soon, but have had a busy morning so have not had the time yet.
The ITB cleaner is new, the first thing we did was to try another ITB belt and we had a used one in storage, with a brand new belt and cleaner.

Swapped Laser Scanner Unit from another machine and the problem is gone! Guess I should have tried that to begin with, but thanks to all those who replied!
