EPSON All In One Printer Repaired
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.
