Could use some help on this one. The 5530 gets wavy lines off and on. Checked the CCD, LSU and Main PCB. Updated firmware. Issue will go away and come back later. It happens on internal prints as well as copies. Any ideas would be appreciated.

The 5530 is famous for cracked and arcing Trans-Sep Corona Blocks.

Only seen a LSU do that on 5530s. How did u check the LSU

good call...tech..that is the answer bd sensor on the lsu...unless ..denden is dealing with a bad reg clutch...a&B always a pain in da neck to replace...



DUMMIETEK...aspire to be myopic...

The one the only, LSU gives in termittant wavy print. Nevr seen that before, and never seen it since....

Is this machine where you take the top of the machine off to access the laser??

If you mean the scanner assy, then no, just access under the eject cover.

And the multimeter says the ground to neutral voltage is ___?

"hmm now that you mention it it only seems to happen when the microwave is on"

Ive seen two 5530 do this. replace the laser.

try contact cleaner on the laser wiring connector.
