    [Misc] C454e Funny Prints.

    Good day Peeps.

    Please excuse my English.

    I Have C454e. Lately the printer prints like this.

    ( Note all drums haven been replaced a while back and def refill kits. NON OEM. Please do not judge me, in SA prices is insane and if you can get OEM parts your are very lucky. Even Minolta retailers here use non OEM.)

    I have a small printing business, in my small town.

    Barely surviving covid, as for our country is in state of disaster for the past 2 years. Business is really slow, and I try to keep the shop to help locals out with prints, as for I am the only person rendering the service here.

    Okay my printer prints fine one day, and it prints like this ( See image 1 attached ), it randomly differs from colors.

    After taking these steps it will work for a day or 2.

    Step 1.Manual add toner to hopper and fill toners. - Sometimes problem goes away sometimes not.
    Step 2. Do Stabilizing and gradation - Sometimes problem goes away sometimes not.

    Greens would become blue, red would become yellow etc. It differs every time.

    I am in need of any advice or help, as for financially I cannot replace the printer, nor rent a new one. ( they are bogus with prices here, hence I saved up and bought a refurb 4 years back.)

    I am losing money for more then a month now, with all color prints, and my head is standing still now. I did have 2 techs out, one says it is the main board ( but why sometimes it prints fine for a day or 2 then starts again.)
    Other tech said firmware, and I cannot get hold of any FW as for my local Guys Charges me R2500 ZAR for it.

    Any help would really be appreciated. I can also Provide my WhatsApp number to do a video call, and show how the printer is printing..

    Hi
    Cant really make out from the pictures.
    Which one is what it should look like?

    Are you using generic toners?
    How do the half tones look at 255 and 120?

      As Brett suggested, when it is printing lousy, print out halftone pages for each of the colors, CMYK. Do it once at the full bleed of 255 and then again at 120.

      In service mode, select 'Test Mode' then 'Halftone Pattern' Select the 'CMYK' button and hit start. It will print out one of each color on whatever the largest piece of paper is that's in the machine. When the first round is done, key in the number 120 and hit start again.

      Scan those in and attach them to a post on this thread.

        The pictures aren't too clear, but from what you're describing, it could be an issue with the developing units. Further testing would be necessary. I agree, run halftone or gradation patterns to see how the individual colors are coming out.

                    Hi Thanks for the reply and input..

                    I doubt it, I tried to look very closely now, Nothing on the papers in front of me. I think is the way my camera took the pictures. I did not scan the papers, I took photos..

                    Thanks again

                      Print the half tones for service mode. Also print the demo page.

                          That's what i thought....there's cyan all the way to edge on all the colour prints - apparently it's due to them being photographed...no way you can see the problem from those samples

                            this is showing signs of hv being overdriven, because of worn out developer units. looks like magenta is empty. and cyan over entire page of every print looks to be either over toned or filled with just toner.
