I have a similar problem with updating the firmware for my Pixma Pro-100, that I have not yet been able to resolve. However, I am updating from firmware version 1.020 to 2.031. After reading all of the posts here, I didn't want to start a new thread since it is highly likely that my issue is the same as the issue in this thread, i.e., updating from ver. 1.1 to 2.031. Here is a description of 1. my system, 2. printer, 3. What I did in preparation for the update, and 4. Specific details on what exactly happens during the upgrade process. Much, but not all, of what I present in Part "4." below has already been posted in this thread. However, I hope it will be useful to those having this issue and also for any Canon techs for the information to be pulled together here, with a precise description of the events leading up to the error.
1. PC running Windows 10 Home ver. 1909 (64-bit OS build 18363.836, intel i7-4770 cpu@3.4 GHz, 32 GB ram).
2. Canon Pixma Pro-100
3. I usually run my printer via wifi. I followed the firmware upate procedure correctly by connecting with a USB, but the printer was not being recognised. Therefore, to prepare for my second attempt I did the following: I deleted the old printer driver and installed the latest driver (ver. 1.06, 07/01/16; file name: p86l-win-pro_100-1_06-ea32_2.exe), available on the Canon USA driver support page for the pro-100. After driver installation, I selected the option that I will be connecting the pritner via USB.
4. Here is a precise description of the steps that I then went through during Firmware upgrade, and the resulting error message:
START
-Turn off printer (which is now connected via USB to the PC).
-Turn on printer. Wait a while until the printer completes it's "initiation noises". Result: Steady, white light shown on top button on front panel of printer.
-Launch Firmware updater program:
-click "Next":
-click "Start". The top button on the front panel of the printer now starts blinking white at intervals of one blink at a time, and the following screen is shown on the PC:
-the above screen stays on for a short while (about 15 seconds), and the white light on the printer continues blinking as described above.
-After the approximately 15 seconds, the PC makes a sound prompt, indicating that a device has been disconnected from the PC. Simultaneously, the top button on the front of the printer panel stops blinking white, and now the middle button on the front panel of the printer starts blinking orange at intervals of three blinks at a time. The firmware program then presents the following screen:
-the screen above stays on for about 30 seconds to 1 minute and during this whole time, the middle button on the front panel of the printer continues to blink orange at intervals of three blinks at a time.
-after the 30 seconds to 1 minute has passed, the following screen is shown:
-While the above screen is shown, the orange light on the middle button of the front panel of the printer continues to blink at intervals of three blinks at a time. The printer remains in this state until "OK" is clicked.
-Click "OK". The firmware updater program closes. The orange light on the printer stops blinking and the printer shuts down on its own.
END.
