THIN lite "pink' lines only on color prints

[fshead]

Usually the dirt from the shield glass is from the inside. So cleaning it with the stick that comes with the machine will not do the job. We ask our refurb team to open the laser unit and do the cleaning of the glass with recommended cleaning materials/cloth.

thanks
I get that it can be inside but I usually dont pull the laser unit unless the machine had
1 a major toner spill
2 a machine that has dirt all over itself
This machine had neither.
I will go back and pull the laser unit

I agree with cat that it is a void not a line. If you use Printer SP 1103-002 Color Pattern, you should be able to see them. Clean the laser shield glasses and repeat Color Pattern.

thanks
but the printout looked good as did single colors.
I know about developer unit doctor blade voids from earlier series that sat too
long in a hot warehouse and had the developer "clump" up and cause voids.

Do the lines enlarge or reduce in size?
If so, the lines are cause by dirt in the optics.

To be honest
I had to run out after 45 mins as i was on a meter
with a 10 min walk,where they tow you.
I will return this week
thanks

It does look like toner/developer clumping at a doctor blade. I usually just print a blank page with background color for each cyan, magenta, yellow and black. The line will be evident on one of them. Take a feeler gauge and shove it between the mag roller and doctor blade at the spot where the line is and rotate the mag roller back and forth a few times to break up the clog. Just had to do this on a c3300.

I had kind of same thing turn out to be optics were dirty. i had replace dev unit and drum assy still had lines then clean optics and it went away.

Dirty optics will not cause lines or voids on prints only copies.

Dirty optics will not cause lines or voids on prints only copies.

Don't forget about laser optics. There are mirrors inside the LD unit, and there are the laser shields you clean with the blue stick. Foreign material on these will cause quality issues on prints.

ok.
this account ghosted on me when i drove an hour to service it and i made them wait till i had another call nearby.
I had a full color test print from service mode and saw no drop outs but stopped by another copier company where i get parts and showed it to
their shop guy a few techs doing shop work.
They didnt see anything in the test sheet till they put it under a bench lite that magnifies,like jewelers use.
and then i could see faint voids in yellow.
So I returned and yes there was some dev unit voids from clumps in dev unit.
I cleaned up and big pieces and good to go...
thanks all
