Error E4 On Canon Printer MP145

Error E4 canon MP145

We have faced error E4 on Canon printer MP145 by yesterday. The error occured after refilling the cartridges (black and color). After re-install the cartridges into the printer, we turn on the printer and the the error code E4 displayed on 7 segment LED indicator.

How to solve this error..? It’s very easy..!

There are three buttons on the printer, that are black, color and stop/reset (look at the picture). Simply try to press one of them for about 5-10 seconds. Your printer should be work correctly now… It may be work for other PCS (Print Copy Scan) printer types of Canon.

Good luck.
