Yesterday I just canon MP150 printer service with the damage code E42 on the LCD screen. I think printers need to be reset, but it turns out after the Canon MP150 printer is reset the damage was still the same.
Finally, I tried loading the printer, I check all the mechanics, it seems no one is problematic. I try to raft back and tested it still the same damage. Finally I asked the same mbah google and it turns out that E42 MP150 Canon damage caused by a scanner that does not work perfectly.
Finally I tried unloading Scannernya, but it looks OK - just OK. I suspect that the data cable (like tape) that connects between a scanner and printer MP150 Board. Test my cable, and my guess was correct, there are some broken wires but not visible from the outside or from the physical. Want to buy a spare part not dapet kok cable, I finally cut the cord which is roughly broken, then the cable in the peel right side. I plug the printer again and turned the printer back to work normally.
Thus my experience, there may be a printer friend's apartment that same fate with the Canon MP150 printer that I have just E42 this service .,.....?
