CLC5151 background

[macuk]

When running A3 with heavy coverage of light colour (orange) I am getting a black background (swirly lines) at the front edge. Have changed drums but no joy. Any ideas?

Are you setting up the cassette for heavy stock? It adjusts the transfer and sep currents for heavy stock. If it is on the lead edge the paper may be riding up and needs more sep current.

Also, how many copies since the last developer change? The black background may indicate time for new developer.

Sorry dude but new drums also mean new developers.

Background of Swirly edge lines could mean your HVT box is bad>
they control the upstream and down stream voltages for the cleaning rollers in Drums

if issue is on Copies and Prints> see below
Depending on what color is causing the background
troubleshoot the problem by swapping around the Lasers from one color station to the other
but you must remember to input the Laser values in service mode which are printed on top of the Laser.

Ensure that the Drum Ground contact makes a good connection with the grounding pin on the machine frame. Replace the contact if it is badly deformed. on front door-see pic example

how often do u do a full calibration

post some single color PG5 PRINTS/
And post pic of your issue

Replace the itb cleaning blade, it's not that expensive. Sometimes the dc controller got the voltages wrong. Needs a dcon clear to get it right, don't forget to put adjust values back in e print out a p-print.

if the ITB cleaning Blade was poor ,
it would effect all Colors while cleaning off ITB

If background issue is from one color, there are procedures that need to be followed for it

oops, my mistake. I did think he was talking about a CLC5100, thanks for making that clearer.


Can you give more info about the "front edge". Do you mean as you are looking at a big stack of paper, black swirls can only be seen on the edge. Or do you mean background on just the front margin?

One other thing to check is the springs under the secondary transfer roller. Open the fuser drawer and lift the secondary transfer roller as if removing a jam. Those springs pop off or the frame breaks. Once this happens that unit won't sit against the ITB correctly changing the angle the paper goes through, which can cause marks on the lead edge of the paper or jamming.
