mptool for Canon MP printers MP150

Hello, I'm new to this forum.

I've just used mptool, having put an MP150 in low level mode first. The mptool is said
to have worked on the MP150 by danlcc in another forum. I've reset everything with
mptool, but still when returning the printer to normal mode I still get the error E5
message. If I run mptool again, I still get 100% on all cartridges.
If I read the MP150 eeprom with mptool I get a small file of 512 bytes consisting of
a single repeated datum. This is obviously not the printer's firmwear. Maybe there's
a communication problem between mptool and the printer.

Any suggestions?
