    konica minolta c300i image smearing while printing checks and labels

    hi everyone. first off I have one of my many machines smearing the image on checks from tray 1 and avery labels manual bypass tray, I know there is settings and these labels are for copiers as stated on the package. but it still smears sometimes. regular copies from both trays are great. so I know its a setting. I have in structed customer that thicker checks from tray 1 would have to smear because it doesnt know its thicker paper. so for reguar checks tray on would you go thick one or two? also avery labels I know you can only run one sheet one time through bypass. any other thoughts on why they would be smearing? the drum count is at 4000 just replaced black the colors are like 15k fuser seemed fine. but its an original fuser with 178 k on total machine click. again.. reguar copies are fine 20 lb paper. any thoughts? thanks everyone

      Thick1 should be enough, but there's no harm in experimenting for the best results. Glossy media could account for smearing (glossy requires one increment hotter in the media type), but I think we can assume that checks are not printed glossy. A worn fixing belt could also account for it, but I think you'd I have caught that.

      Ok, I thought of one more thing: What if your checks are printed on a device that has a cooler fixing temperature than the bizhub? The pre-printed image will definitely smear regardless of setting. The only fix for this is to pre-print your checks on a device that runs hotter than your bizhub, or ink.

      Let the customer know that there will be some additional warmup time, so don't panic if your check doesn't spit out immediately.

      I discourage changing the service mode setting for the fuser, but please feel free to try any media type you like, at least when experimenting.

      Another consideration is: "How much coverage?" A 350% fill image is going to take a lot more heat to fuse than a 5% black fill. Again, I suspect it's just text on the checks. Maybe you'll see something different. =^..^=
      If you'd like a serious answer to your request:
      1) demonstrate that you've read the manual
      2) demonstrate that you made some attempt to fix it.
      3) if you're going to ask about jams include the jam code.
      4) if you're going to ask about an error code include the error code.
      5) You are the person onsite. Only you can make observations.

          thanks black cat.. I always appreciate you. the labels are black and an address only very minumum coverate. the checks are also black minimal coverage. you are right.. I will try to do a thick 1 or 2 and see what they are doing.. we had some avery labels that s pecicially said printer. they were horrible. and yes the thick paper settings make the machine print way slower
          they will be printing from a computer so ill look for the settings and try a thick. just hoping I wasnt missing something easy so I wrote this post

          thank you

              I just added an edit to the previous post, here it is:

                  Turn off smart fuser control. System 2 page 3 prohibit. This will delay first copy very slightly to allow heat to reach proper temp. Thick 1 or 2 should work. Had 2 last week with same issue.

                      even if they are Avery labels i hope they are full page not that borderless EZ peel crap that destroys belt and drums.
                      had a few machines they continued to run ez peel labels and thats exactly what they do....at an inconvenient time and place for everyone.
                      i have battle scars from warning/debating with customers on media use and long term capabilities of the machine.
                      i gave up fighting when the rule was after the 2nd warning you pay for affected parts or lose the contract altogether.
                      we were paying them to destroy consumables. it was insane.
                      We know a thing or two because we've seen a thing or two.
                      The medication helps though...

                          Ever since the 8 series weve been turning on engine switch 13 in service, enhanced security (stop 0 clear) for cold fusing on first page after sleep. Does anyone know if it still applies to i series? You can step up fuser temp in service and/or set default paper type in bypass to thick1.

                          Curious if you have customer open/close the door first to cycle or just print a sacrificial first page, does it still smear?

                              Engine SW 13 is still a think in the i series. Engine SW 12 is also a new thing that is supposed to be turned on if you have the new model fuser.

                              I had one customer having that issue ended up they would save the word document and then when they opened it in "PDF" form it opened it in EDGE browser and they printed it off of that. Once we got them acrobat and been printing from there they have had no issues.

                                      You really need to read up on service manual. Don pointed at these directly.

                                          I know you said that the labels were for printers , just make sure they are for laser printers and not ink jet printers. I've had customers tell me that they used printer labels and when I ask to see package they came in it said ink jet printers

                                              Well, found it in second attempt, I was looking at the wrong bit switch section, long day lol.
                                              So this gives the fuser a little more time to heat up, it might help if you have fuser issues on first pages.
