Epson 8550 Not Powering On After CISS Installation: Solutions and Troubleshooting Tips!

Question:

I tried to install a CISS (Continuous Ink Supply System) on my Epson 8550 printer, but now it won’t turn on, and I can’t reassemble it. Can you help?

Answer:

So your brand new Epson 8550 won’t turn on after having a CISS installed? Here are some places to troubleshoot:

You may want to double check all the connections inside the printer first. The external installation of CISS requires opening the printer, closing screws, adjusting various parts, and sometimes loosening internal cables. First of all, gently have the printer opened again and check the power cable connection to the mainboard and other components. One of the common reasons for the printer not turning on is a loose or poorly connected cable. Make sure everything is locked safely in.

Second, it is possible that the mainboard shorted during installation. This is possible if any liquid accidentally spilled over the electronic components such as ink. Look for signs of burning, discoloration or corrosion on the mainboard. Some components of a printed circuit board repair it can be functional, while others may require the process defined in printed circuit board assembly (PCBA).

Finally, remove the CISS entirely and reinstall the printer’s OEM cartridges. Some printers, such as the Epson 8550, are written to automatically recognize compatible ink systems. In the event of detection of a fault of the CISS by the printer it may refuse to start. Sometimes resetting the printer itself to its original condition with the factory cartridges can help it boot back up. Only after you have verified that the printer works properly you can try installing the CISS once again, while making sure that all the steps are carefully followed and take all necessary safety precautions.
