    [CQ] CLC 5151 cross feed line

    Hope someone can help me with this.

    I have a CLC5151 that leaves a dark fuzzy line cross feed at the trailing edge of an A3 copy. The line is always at the same place 5 inches from the trail edge of the copy.


    I have tried changing the fuser which initially appeared to work but the line came back, I have also tried changing the fuser speed in level 2.


    Oh I should mention that this fault is only apparent when using 200gsm or higher card. If I try 160 or even 80gsm the copies are fine.

    Would welcome some help on this one please.

      I hope the scans give an idea of the line. Like I said it is only on stock 200gsm and above and always in the same place 5 inches from the trailing edge.

      many thanks

          It sounds as though you've defined the upper limits of how heavy the media can be on this model.

          I spent several hours with an Okidata on this problem. When the paper arrives at the bite of the fuser, since the heavier paper cannot buckle it gives a little hesitation which you can see in any part of the image that happens to be transferring at that moment. If they always printed the same media, maybe you could reduce the fixing pressure somehow, but then there's always the risk that you'd get partially fused images. My customer knew perfectly well that it was the paper weight. They had done the same job previously with slightly lighter weight stock. Technically the media was at the upper limit of the machine's capabilities, but we all know that there are a lot of other properties to paper than just weight.

          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.

              No the fuser wasn't new the cost of those things is extortionate.

              Yes when I put the replacement fuser in the fault appeared to be cured no blurry line appeared on the tests I did.

              As the fault appears so far down the A3 sheet the lead edge is just coming out of the machine and has already gone through the fuser.

              it does look to me like the paper has paused during transfer at that point but it should be both in the fuser and delivery rollers at that time,

                  The spec for the machine is up to 258gsm through the manual feed so they wont accept me telling them that the papers to heavy, especially when they have been using it succesfully for some time.

                      Are you calling this paper HEAVY 2 ?Is it 2 sided coated, or glossy?

                          I had several cases with that problem.
                          I don't think replacing the fuser unit will solve the issue. Should be some design issue.
                          I think it shows up if paper is over 250 gsm.

                          But it shows up on A3 and NOT in A4 which rules out the fuser unit and it means that that part of the paper (with un-fused image) is touching some part. I believe that part is a metal roller (if you know what I mean).

                              Actually the brochure (see attached) states on page 7 that it does up to 253 gsm but only through the bypass...

                              ...but it also states on page 7 that you can offer everything to your customers and never turn down a job...and on page 10 it boasts that this piece of equipment can deal with anything...

                              So I really wouldn't put much stock into what a manual or brochure says it can do because obviously it can't. All of the digital press customers out there and the salespeople seemed to have this idea that the machines costing $100,000 would last 30 years and do a 100 million+ prints just like their million dollar offset presses...well obviously they were in for a surprise.

                              Just because you can do it some of the time doesn't mean you can do it all of the time. I had a customer that wanted to print addresses on a one sided UV coated post card with a black and white laser device and could do a hundred or two hundred and then the drum surface and fuser got all bent to hell.

                              "Well it worked fine for the first few hundred why can't it do it anymore?" Well, because you were fucking up the machine during the first few hundred and now it's broken. A new fuser and drum fixed it until they got messed up.

                              On that machine you're going to just have to keep replacing the fuser with that paper weight or not use that machine for such heavy paper. Also, you said the replacement fuser wasn't new and remember you're not going to get full rating on the fuser at higher paper weights.

                              ...AND I just love how the copytechnet forum for copier stuff always thinks that the word "fuser" is mispelled!

                                  Heavy 2 is being selected, its single sided and not glossy.
