    Second opinion about the Fusing Sleeve Unit

    Good companions of Printing and Copying.
    I am assailed by a doubt and I want to turn to the sages of the forum.
    The Fusing Sleeve Unit systems, so that it has been possible to verify through the documentation, do not indicate anything that in the preventive ones they must be lubricated, and only indication is made to the replacement, in case of breakage. Has anyone been able to assess an estimate of use to lubricate them with silicone and extend the useful life? Or does the wear and tear occur in the same way, and is the waste of time in disassembling the Fusing Sleeve Unit irrelevant?


    I comment because in some models and made this "re-lubrication", increasing the pressure a little (a few millimeters) the mulles that act with the Pressure Roller, thus gaining some more efficiency in the fusion.
    "ALL WILL BE WELL" The battle cry that most inspires me to follow, from the DC's Comic character that I admire the most. And I feel satisfied with being better every day, and with using Gnu-Linux as my usual Operating System.Apologies for my English, it's not my mother tongue and I'm helping the translator.

      Not sure if you are talking about the aftermarket sleeves used on Kon/Min copiers but they do not use any type of lube and may cause the sleeve to slip. I know with HP and other OEM printers it is very important to lube the fuser sleeves!

      Added after original post: Sorry just realized this was in the Ricoh forums. I don't work much on Ricoh but thanks for the info.

          I have tried lubing them to get more life, it helps. I've had a mixed bag using non-oem sleeve only replacement. Been using the hp white thermal grease. Do it all of the time on Canons. Canons will get some random jamming when fuser sleeve drags, I imagine the same for Ricohs.
          I've proved mathematics wrong. 1 + 1 doesn't always equal 2.........

                  These units are almost impossible to assemble if taken apart, so no I never greased the sleeve on any Ricoh fusing units.
                  Please start you post with brand, model, problem.

                      We always do that with Canon and HP and keeping that in mind i have done that on Ricoh 54 and 55 series grease that we use for other sleeves in other brands using same Heat resistive reduces the friction between heating pad and less pressure on drive gears and getting more life out of sleeve, instead of replacing the Complete Sleeve Assy' only the sleeve and Thermistor's. it takes some time for saves allot of bucks and with passage of time whole process can take about 30 minutes to get it done.

                          I have never lubricated a sleeve unit in use, yes when we have tried third party sleeves but the duration of these has not been satisfactory so we only mount new and original sleeve units unless the customer breaks the sleeve and is well below of its useful life that then if we put a compatible sleeve.

                              Had a guy work with me for about 6 months once, he used to work on Toshibas and some other brands and was telling me about putting silicone oil on the fuser sleeves. I warned him against it, he tried it on one of the Ricohs in our workshop anyway and it caused a load of problems immediately, he then spent about 30 mins trying to wipe away excess oil etc until it started working again. Needless to say that put me off the idea forever, doing it to a Ricoh

                                  I use to replace the Fuser Sleeve as a unit, so it is not nessecary to lubricate
                                  nothing, as per ServiceManual. But,
                                  when the situation needs a partial refurbishing, the aftermarket Fuser Sleeve Kit, or the Oil Pad Kit,
                                  contains a syringe with fuser oil to lubricate the fabric part of the Oil Pad. This is normal and i replace both of them.
                                  Lately, i found an aluminium pad with teflon and it seems that it is not nessecary to lubricate the Fuser Sleeve,
                                  internally!! It is written definitelly on the frame of the pad. It seems to work...and it is very cheap.
                                  There is also a "metal" aftermarket sleeve only, but i don't know the difference, i mean where and why i can use it.
                                  Of course, the pressure roll replacement is a 'must' every time something goes wrong with Fuser Sleeve...
                                  My two cents...

                                      well look you
                                      A client with an mpc 5502, we put the generic fuser sleeve on it and we had to put oil on the pad so that it lubricates and rotates well, but the strange thing was that it did not last at all, it began to brake and jammed for sure, so several times it touched us put oil again.

                                      this last time it didn't work because he put a little too much oil and damaged the lamps generating sc 552 and 554

                                      Until now I found out that they NEVER turned off the machine, NEVER completely that the oil dried

                                      The manager says they never told him to turn it off.

                                      I tell the manager...is it that you don't turn off your stove, you never turn off the TV, the radio, the car, etc?

                                      It's the same with the machines, once the day is over, you have to cover it up for security unless they work 24 hours, that's not the case here.

                                      we program it to turn off at 7 pm every day in case they "forget"

                                      we should have put original fuser sleep

                                          Thank you very much for the comments, it has been very enriching the different experiences.


                                          Both the good and the bad, will help me to assess certain situations that arise.
