Km 2550 print smears

[stevee104]

Have a machine that when copying and printing on 8 1/2 x 11 paper it looks like the print is smeared, it does not do it all the time
so i am stumped,have put in a brand new maintenance kit and still the same problem and it does it it same spot machine only has 50,000 pages on it. Have samples attached.

These machines are known for the laser unit motor to cease up. most of the time removing the laser unit and putting a drop or two of triflow oil solves the problem.
do a copy run and look at the output, when you see it start appearing on the output copies , open the door while it is doing a copy. examine the drum image, if drum image is distorted, then laser issue. You should do the laser motor anyway. been long time since seen this machine.

What is lead edge? 8 1/2 or 11.... What is the humidity level like where the copier/paper is stored? Looks very similar to an issue I ran across a while back, the machine in a church basement where there was a humidity issue.. not extreme, but enough that the fuser was causing water droplets to hit the paper causing image distortion... not all the time, but enough to be noticed occasionally..

11 is the lead edge , paper has been change with paper from 3 different locations, machine has been move to the shop
for further testing, still leaning toward laser myself but i got to take it out and test in another machine.

Update firmware & clean DV units per bulletin just released.

The KM-2550 IS a different machine altogether from the TA-2550ci tmaged.

You are correct sir ! I didn't catch that it was the old dude !

Re: Km 2550 print smears

It looks to me like the drum cover has not retracted all the way and maybe the paper is rubbing against it as it then goes into the fuser unit.

Re: Km 2550 print smears

I would lean on what copydocinc suggests, its something scrapping the copy as going thru the machine after it leaves drum and before it reaches the fuser. Is the image like that on the drum? Have seen smears similar to that on other machines(though different makes) and it has been drum issues. Is it always same side? Is it in different places? Off and on? Try different paper sizes?

Re: Km 2550 print smears

I've been having this issue (also with a church) ongoing now for a couple weeks. However my problem has been seemingly more inconsistent than yours. I could never repeat the problem while on site and most of the customer's examples had different patterns on them. One of the example sheets even had splotches as opposed to lines. I decided to try swapping both the drum and dev at the very least to rule them out and they have since called back. I'm beginning to lean towards something more environmental, since usage/volume and occurrence is sporadic at best. My current suggestion to them has been to wait 10-20 minutes after powering the copier on before making copies.

So you think you're getting condensation on the metal guides near the fuser, and that the condensation is smearing the toner before it is fused? If they follow your recommendation and it works, you're probably right. =^..^=

Re: Km 2550 print smears

I have seen this problem several times and it was caused by the drum unit.mainly it happened on machines using generic toners ,katun .ikon etc. Vacuum the dev and clean your main charge corona as well ,use original toner

Re: Km 2550 print smears

Regional tech stopped by the other day as he was passing through town seems there was a service bulletin on this machine for the Mylar film on
the exit unit building up moisture on it that was smearing the toner on it. never would have thought that's where it was building up and smearing.
