Toshiba E-Studio Print Quality Issues

Hello everyone!

I have an old Toshiba E-Studio 120 printer, and I'm having a print quality issue: when I print a document, the ink smudges on the page and I end up with a reproduction of a pattern lower on my sheet, which is quite annoying (see the photo below).

I suppose it's due to clogged print heads, or maybe the alignment of the latter, but the printer is too old to handle all that automatically.

Can I do it myself without risking damaging everything?

Thanks in advance for your replies!

    Hello,

    In summary, the printer is concrete mechanics, without any mystery...

    1° Is the background image really white? If it's even a bit gray, ink will drip...
    2° The seals of the ink cartridges must be airtight; otherwise, a bit of air gets through, which releases pressure in the ink channels... and it drips.
    3° The underside of the print head (facing the paper) should be dirty with ink buildup, it needs to be cleaned... by sliding a folded paper towel between the head and the paper path... pushing it and moving the head so that the paper towel comes out the other side... Moisten it lightly with window cleaner... and make back-and-forth movements with the head to wipe underneath... or even leave it there overnight..
    4° You also need to clean the rubber rollers that feed the paper... because printing ink accumulates on them and marks the next page... It all depends on how the printer is designed...??
    Normally, the rollers feed the paper by pressure upstream of the printing area... and do not exist downstream of the area; there are wheels with small spikes, there is no support. So make sure these spikes are clean and not filled with paper dust that acts like blotting paper and transfers onto the paper being printed..
    5° It may also be that your ink is too liquid... but it's hard to say how to adjust that parameter

    There you go, it's just about detail and precision... a bit like a midwifery job.

    Since it is a laser, you may have a drum erase defect because it is too old. If it were the blade, you would have streaks and not the print transfer.
    You can already clean the corona wires, it won't hurt.

    The other possibility is the fuser unit (fuser) being too dirty. This can come from the use of a compatible toner that isn't really compatible.

    Personally, I don't think it's coming from the drive rollers; the distance of the image transfer makes me think it's a roller of a fairly large diameter.

        Yes! But the model is ink-based.

        Toner is powdered ink ...

        If it's this model, (with or without automatic document feeder) it's a laser printer.

    So, a thousand apologies... I didn't realize that this printer was a Laser... Sorry, I saw ink and cartridges... so inkjet printer... Mistake

    So everything I said in my POST is useless for this type of printer

    As @contrariness said, it must be a drum report that prints its second rotation on the paper... and everything he said is accurate.

    I think these printers don't have maintenance visits unlike businesses and everything gets dirty inside; therefore, you have to do this maintenance visit yourself.

    Here is the corresponding technical training http://bmtec.free.fr/Doc/Toshiba/estudio120.pdf

      Hi Jeannets,

      I don't quite remember the maintenance on those old printers..
      I even think there's a light bar that is used to erase the ghost image on the drum.. The blade removes the toner that hasn't been transferred onto the paper, and behind it I believe there's that famous light ramp...

      But as you said, it must be a serious lack of maintenance that's causing this!!

      Regards.

        Yes, I'm not familiar with this particular model... I know that there are sometimes lamps... some are in the cooking cylinder at the outlet, in fact, it's the heating of the cylinder, I believe it's an infrared lamp...?

        It's mainly a drum that is not eternal... unless changed with the toner... and several corona wires that get dirty, there is a precharge of the drum and also a erasure, all of this is strict... then there is the cooking on this burning cylinder, just at the outlet...
        The faulty wiper blades leave black and parallel streaks, that's not the case
        There you go, but the PDF document from Bmtech is a training resource, quite well done and in French, which should help to "hold on to the branches".

    I therefore cleaned the inside of the printer as much as possible by disassembling the mechanisms, but when I tried again, the result was even worse!
    I think I will call in a professional, as it seems to go beyond simple clogging...

    Thank you for your responses!
