Pro-1 problem - Sorry!

[finstp]

Hi,
I have been trying to recover a Pro-1 printer with an apparent absorber pad problem. The printer is old, mine new from 2015, but has only been used for about 100 prints and 2 sets of inks for various reasons. I foolishly bought new (genuine) inks and have printed a few more, beautiful, prints, but now it is showing the 8 alternate flashes of amber and power LEDs.
I finally got a copy of service tool v3400, but it isn’t allowing me to reset the absorber count. It does seem to be going into service mode with the usual 5 press sequence, appearing as Canon Device in USB, but it continues to boot up, ending with the 8 flash sequence. With v3400 I can read the EEPROM, but any other commend gives Error 005. It may well be totally bricked, but my AI pal, ChatGPT, has suggested getting hold of service tool v4720. That one I can’t find online. Can anyone help with this? Or suggest alternative solutions (don’t mention the skipP

I tried to look for v4720 of the service tool, but found none. Links are either dead or AVG blocked access to the site due to malware threats.

Instead you could buy a newer version from eBay. Scroll down to see a list of supported printers. The Pro 1 is on the list. You might be lucky that this version works with your printer.

Here is a post with a list of error codes for the service tools. An additional error 009 means service mode operations cannot be performed due to a mechanical error in the printer. Error 005 means that the printer is not recognized by the PC. That is strange as normally when the service tools work all operations are permitted. Maybe the use of service tool v3400 blocked access to service mode so now the printer can no longer enter service mode?

PeterBJ, thanks very much for your reply. In fact, I have managed to solve the problem entirely. I have made a new post explaining the (nearly) full gory details of my attempts.
