Computer is an iMac 2023 now running osX (MacOS) Tahoe 26.4. Canon device is PIXMA TS9521Ca, new in 2024.
Problem is, MacOS no longer recognizes the scanning functions of the device. The "Open Scanner..." button that used to appear in the Settings > Printer & Scanners > TS9500 Series is GONE. Also, Canon's IJ Scan Utility Lite can no longer find any scanner on the network. Third, Apple's Image Capture program just indicates zero devices available.
So, I've done this several times to no avail:
Removed the device using MacOS Settings > Printer & Scanners > TS95000 Series > "Remove Printer...".
Followed https://ij.manual.canon/ij/webmanual/WebGS/WGS/wgs_start.html?lng=en&type=setup&area=us&mdl=TS9521Ca... to re-install the drivers and utilities.
After doing those steps, the TS9500 Series device STILL appears as ONLY a printer in MacOS Settings > Printer & Scanners > TS95000 Series. And the IJ Scan Utility Lite and Image Capture programs STILL don't find any scanners available.
I have even performed a Full Reset from the TS9521Ca's screen menu, but this station didn't improve after.
Please suggest what I might be missing here. By removing the device as described above, would that leave any driver elements from Canon behind in MacOS that detours away from a full "brand-new" install?
Thank you in advance.
PS: Full Disclosure! A week ago, I temporarily connected a new Canon TS3722 printer/scanner to this MacOS, and followed Canon's directions for its installation. Everything worked great, theTS3722 printed and scanned well from MacOS. I disconnected the TS3722 and gave it to a relative, and I removed the TS3700 Series device using MacOS Settings > Printer & Scanners > TS3700 Series > "Remove Printer...". The TS3700 Series device no longer appears in MacOS, as expected. BUT, it seems that after this exercise, MacOS lost its ability to recognize my own TS9521Ca as a scanner as well as a printer. Are there possibly some TS3700 driver elements left behind in MacOS that are blocking its recognition of the TS9500 scanning capabilities?
