  1. Re: MPC3503 FUSER SLEEVE assembly with lamp into a MC4503

    +1. Every halogen lamp I ever handled has volt and and watts specifications printed right on the ceramic end. I would be very surprised if they were rated the same though. =^..^=
  2. Re: Kyocera 4551ci - wide white band on black only

    The worst I've seen was an iron foundry.

    A byproduct of the iron smelting process is carbon black. This fine black dust invades every part of the building, and is clingy. The first time I went...
  3. Re: Kyocera 4551ci - wide white band on black only

    The one I repaired was in a factory. Their manufacturing process left 1/2" of fluffy brown ... like welding dust, every visit. I found it amazing that the machine worked at all. I was not...
  4. Re: Kyocera 4551ci - wide white band on black only

    Is it a particularly dirty environment? =^..^=

    Re: Colortrac SmartLF Ci 40

    Wow! Is there any of the original image? It all looks like "noise" to me.

    I've never seen anything like this on a Colortrac, but not any one of the CIS(s) could cause this sort of image all the...
  6. Re: Kyocera 4551ci - wide white band on black only

    +1 on the stalled laser slit glass cleaner. IIRC the cleaner is part of the laser unit itself, and not purchasable separately. You will need to entirely remove the laser unit to repair or replace...

    Re: kyocera M6526 grinding noise

    I got a noise like this after doing a PM kit. I think the noise you may be hearing is the timing belt that drives the primary transfer cleaning. It's a very long thin belt, and the new transfer...

  9. Re: need help,how to solve white line on paper kycera km2050.

    These models are well known for accumulating ozone buildup on the mirrors and slit glass in the scanner optics. Typical glass cleaner is not strong enough to remove ozone. You may need to use 95%...
  10. Re: need help,how to solve white line on paper kycera km2050.

    I'm going to guess that there's an obstruction under the doctor blade, in the developing unit. Such obstructions can shift around. Or you might have a buildup of toner on the developing roller.

    Re: bizhub 200 touch screen adjustment

    He did not buy the panel. The story ends there ... because I don't know another ending. I'll guess that it was junked ... unless there's a tech stupid enough to do what he wanted. =^..^=

    That's a good idea! Hytec repairs the boards ... maybe they get more resources than we get.

  13. Re: Bizhub C308 Power Supply Humming Noise - Fuser

    I'll share what we're provided ... which is to say not much. It's been over a decade since we got actual circuit breakdowns. The most you can hope for is pinouts and signal names.
  14. Re: Bizhub C308 Power Supply Humming Noise - Fuser

    Correct. And we saw plenty of bad triacs. I got to learn that lesson on a Mita DC-152Z that came incorrectly wired from the factory. Essentially the heat lamp was ON all the time. The first few times...
  15. Re: Bizhub C308 Power Supply Humming Noise - Fuser

    I think the goal is to reduce energy usage and mechanical noise. It's the same reason that copiers now have 20 or more DC motors <1 amp, and turns them ON only as needed, rather than one 8 amp AC...

    Re: bizhub 200 touch screen adjustment

    Funny story:

    I had a billable customer that used his bizhub 200 only for printing, so when it had an error message (sorry, can't remember which) this customer expected me to install a new control...
  17. Re: Bizhub C308 Power Supply Humming Noise - Fuser

    The light bulb is constantly connected and it's intensity varies similar to that same sine wave. The fuser heater has driver circuitry to pulse ON only at the zero-cross.

    [Dead] Re: cfb 32 km2560

    CFB32 is a communication error between the control panel and the main PWB. So you've approached it from the main PWB side. How about the operation panel, and depending on what version it may have a...
  19. Re: Bizhub C308 Power Supply Humming Noise - Fuser

    Alright, try this:
    V=IR. When V=~0 momentary, 0/R=I or ~0 amps


    P=IV. When I=~0 and V=~0, then P=~0 watts momentary. In practice it's never 0 watts, but you get the idea.

    It took me about 30 seconds with Google to find this:

    Or you could just read the service manual.

  21. Re: Bizhub C308 Power Supply Humming Noise - Fuser

    It's entirely normal for fuser heaters to turn On in pulses at 60Hz intervals (in the US).

    The way I understand the theory, when the AC voltage passes through the zero volt axis (or zero-cross)...
  22. Re: Sharp MXB402 - Paper Jam/New Fuser Unit

    Are you sure that "jamming" isn't really an "L4-16" error code?

    I seem to recall that if the fuser is not changed quite correctly the pressure release cam will break on the new unit.

    [Electrical] Re: FS1016MFP restart printing

    When you figure out how to get the error log and consequently the machine generated jam code or error code, only then we will have something to work with.

    I can wait. =^..^=

    This is not the easiest sample to use for color differentiation, but from what I can tell all the colors are ~40% less density across the board. So ... IF there is a single cause, it's a...
