EPSON All In One Printer Repaired

By on June 4, 2017

In my busy schedule I had a call from one of my customers that his printer was not working. On asking about the nature of symptom he explained to me that printer was making loud noise and stop printing.

So I requested him to visit my workshop to bring the printer for further troubleshooting. Eventually he visited my workshop next day because I already have some consignment on that day.

So next day on my workbench I got that printer that was “EPSON AIO L210” inkjet printer. For diagnosis I have powered the printer and I found that while initialize printer cartridge cradle getting stuck following scrambling noise and front panel LED Indicators started blinking-see photo below:

This printer was having external ink tank so user can refill the ink himself. I have checked ink tank and found up to the mark that means ink supply up to the printer head was ok. So I opened the mechanism for further visual inspection.

This type of problem mainly because either

1)      If cartridge cradle carriage is not moving smoothly.

2)      Timing belt or carriage motor is bad.

3)      Head cable or Encoder sensor is bad.

4)      Encoder strip is bad.

5)      IO Logic board itself bad.

So after power off the printer I have moved the cradle unit by my hand and found it was moving very smooth even no need to lubricate while in this process I found some ink patches on the encoder strip.

So I have removed the encoder strip and try to clean the Strip with dry tissue paper and IPA but unable to clean the ink patches. Hence I have ordered new encoder strip.

After replacing new encoder I have powered the printer and the result was positive and the error gone. That means the culprit is encoder strip- problem  solved.

    Very good job Yogesh. I did not know that such spare parts could be bought since every manufacturer keeps making new models ver fast. Why older models get obsolete very quickly. Epson is not my brand anymore though after my Epson Stylus stopped working after hardly being used within a year. And almost 800 guilder (Dutch: Gulden) were gone, which is equivalent to about 362,57 Euro/US Dollar today.
    I got no warranty after 12 months and never any reply from Epson. And after that I also discarded my previous 840C and 710C HP problem printers some years ago. That both also dried out without any warning. Now I use 2 Brother All-in-one Inkjets that never dry out because they are always connected to the 230VAC main powerline and are automatically spooled if the Ink needs to be re-injected to prevent dried up ink-heads.

      You are right inkjet printers are horrible if you are not using often .just go for Laser Printer.

        I know that many people have and use Laserprinters but they also have their big problems. Like when you place 2 pages with their ink tonersides on top of each other and check out some years later how they look. Often the pages are glued together by the toner that was put on the paper at about 80 degrees Celsius by the Laserunit. And the toner itself is very bad for the environment and our health. And therefore you also need a special toner vacuum cleaner. And they often stink because they produce O_3 (ozon) which is unhealty to. (Only some new Laserprinters produce O_2 instead of ozone which is good). But we still do not know half of the damage done by nanoparticles and emissions of particulate matter. Like toner. Cheers.

    Hi Yogesh, would cleaning the encoder strip with a cotton bud soak in solvent diluted with water work?

    Have tried solution on dried up ink heads and its worked.

    Dear Sir,
    My printer, Epson XP 410, can not print and i do not know if it can receive data but the print dialog box always shows printing in progress. It even instructed that I should change ink but after I changed the inks the problem is still persistence. The driver is overwritten and I do not know how to obtain an authentic driver for the printer. I have also brought two Hp printers and the drivers are not compatible with my windows and when I try it with my windows XP compatible system It does not work. I think I am frustrated and I can visit any certified service store because there is practically none that is available
