PRESS 1052 line

[blackcat4866]

Here's the best part: per the enduser, it only occurs about every 5000 pages!

From the samples, the line is always 32mm from the leading edge, in the crossfeed direction.

The closest I could get to the 32mm interval was at the fuser inlet guide. I'm guessing that occasionally a page levitates over the transfer belt, and when the page hits the bite of the fuser rollers, the page briefly touches the top inlet guide.

The interval is not right for the drum claws. Has anybody seen this one? =^..^=

5,000 lmfao. And I thought my day was hell.

I notice it happens exactly at the spot where it starts laying down toner for the image. Is that just a coincidence?

Look at the voided areas around the lettering. Its monetary arching or loosing charge?
Is it in the same position every time. Its probably happening more often than 5000 pages that is probably the only pages that gets noticed.

It's just a coincidence. Every sample is at 32mm.

Possibly arcing. Yes always exactly 32mm from the leading edge, and usually the first page of a stapled set. But arcing where, to what?

This machine does between 25K and 30K a day, so that's ~6 events per day. Maybe more. Oh yes, 2.5M prints and rising daily.
My enduser said that they stopped using this machine because of the problem, yet did 70K in 3 days on said machine. =^..^=

I've just fought a similar problem on a 1051. Replaced charge grid and wires. The voids around the prints as Allan pointed out lead to this fix.

Its one of those inspector Cluzo cases.
Is that the first page of a stapled set regardless of the page count per set. I would intentional bump the machine to see if i can recreate it.
Thinking that the stapler could cause a jitter is way out there.

I feel your frustration.

I'll do the wires and grid Monday (yes they called back).

like you, I can't imagine the stapler causing a jitter from a meter away. Not enough samples to be very sure of anything. =^..^=

My instructor said it is very common for end users to turn of the main power before turning off the subpower. The subpower allows for a gradual temp reduction that can last as long as 30 minutes.

He warned this action will cause toner to harden and cake up in the transfer cleaning area resulting in image issues, noises and a heck of a clean up.

just a thought

It's worth looking at. Thanks Junior. I'll take it apart and see what's there. On the sister machine it frayed the rear side of the transfer belt at 1.6M, so I've been in there. Curiously, the belt still walks a little to the rear, and I doubt it will meet a 12M yield expectation. =^..^=

Hi,
I would check the earthing of the fur brush inside the cleaning unit. I have had issues on the previous models where the shaft needs to be cleaned that drives the fur brush roller that caused similar problems.
hope this helps.
