Canon MF620C Driver

Canon MF620C Driver, Windows Setup, Prints But Does Not Scan, MF Scan Utility, Offline, Toner, Streaks, and Network Problems

The Canon MF620C is a color laser multifunction printer series used for printing, copying, scanning, and network or USB office document work. It depends on the correct Canon print driver, MF Scan Utility, scanner driver, network selection, toner cartridges, and paper path before both print and scan functions work normally. 

Users most commonly faced printing working while scanning failed, MF Scan Utility communication errors, Windows 11 driver installation problems, offline status, stuck queues, wireless/network detection failures, faded color, streaks, toner cartridge messages, and paper jams.

Problem: Canon MF620C Windows 11 or Windows 10 driver install fails

What users observed: Users trying to install Canon drivers on Windows 11 or Windows 10 sometimes found that the driver did not install correctly over USB. Canon’s Windows driver notes describe cases where the Generic Plus driver needs to be updated manually through the driver INF file instead of relying only on automatic setup.

What was tried: Users ran the installer, tried Windows automatic setup, checked Device Manager, used Have Disk, browsed to the extracted driver folder, and selected the Canon INF manually.

How this played out: The repair path was manual driver attachment. Users extracted the Canon driver package, opened the printer driver update path, selected the Canon INF through Have Disk, and restarted Windows after the model driver attached. The printer entry became usable after Windows used the Canon driver files directly.

Problem: Canon MF620C appears offline in Windows

What users observed: Windows showed the Canon MF620C as offline even though the printer was powered on. Network users saw the printer connected to the router, while Windows still sent jobs to an offline queue.

What was tried: Users restarted the printer, computer, and router, checked Use Printer Offline, cleared the queue, checked the printer IP address, reinstalled the printer, and disconnected VPN software during testing.

How this played out: The fix was offline-state cleanup. Users cleared Use Printer Offline, restarted the spooler, removed stale Canon entries, checked the active USB or network port, and added the printer again. The queue returned to ready state after stale offline status, old port data, and broken printer entries were removed.

Problem: Canon MF620C print queue gets stuck

What users observed: Users sent documents to the Canon MF620C and the print queue stopped moving. One failed print job blocked later jobs, and canceling the job did not always clear the queue.

What was tried: Users canceled all jobs, restarted the printer, restarted Windows, restarted Print Spooler, removed the printer entry, and tested a small document.

How this played out: The repair path was stuck-job removal. Users stopped the spooler, cleared stuck queue files, restarted the service, and sent one fresh test page. The queue started moving again after failed print data and stale Canon printer entries were cleared.

Problem: Canon MF620C prints but does not scan

What users observed: Users could print to the Canon MF620C, but scanning failed. The printer entry appeared in Windows, while MF Scan Utility, Windows Scan, or other scanning software could not find or communicate with the scanner.

What was tried: Users opened MF Scan Utility, installed the scanner driver, installed MF Scan Utility, checked Scanner Selector, restarted Windows, reconnected USB or network, and tested printing separately.

How this played out: The repair path was scanner-side installation. Users installed the Canon scanner driver and MF Scan Utility, selected the MF620C scanner inside the scan software, restarted Windows, and tested scanning again. Printing working did not prove that the scanner driver was installed, so the scan path was repaired separately from the print queue.

Problem: Canon MF620C MF Scan Utility cannot communicate with scanner

What users observed: Users opened MF Scan Utility and saw a communication error saying the scanner could not be reached, while printing still worked. A similar Canon imageCLASS case described two Windows 11 computers where the scan utility and selector could see the device, but scanning still failed from those machines.

What was tried: Users reinstalled MF Scan Utility, reinstalled scanner drivers, checked scanner selector software, restarted the printer, tested another computer, and compared printing against scanning.

How this played out: The fix was scan communication cleanup. Users removed the broken scanner entry, reinstalled the scanner driver and MF Scan Utility, selected the correct MF620C scanner, and restarted the PC. Scanning returned after the Canon scan utility was pointed at the active scanner entry instead of a stale network or local device state.

Problem: Canon MF620C scanner fails after Windows 11 24H2

What users observed: Users with Canon scanning software reported failures after Windows 11 24H2, including MF Scan Utility and ScanGear problems. Canon-related Windows 11 24H2 scan reports pointed to a Microsoft patch that addressed scanning failures after the feature update.

What was tried: Users checked Windows Update, reinstalled Canon scan software, restarted the printer and PC, tested scanning from another computer, and checked whether printing still worked.

How this played out: The repair path was update-state recovery. Users installed the Windows patch that addressed the scan failure, reinstalled or repaired the Canon scanner package, restarted Windows, and tested MF Scan Utility again. The scan function returned after the Windows update state and Canon scan software were brought back into alignment.

Problem: Canon MF620C network scanner is missing while network printing works

What users observed: Users could print to the Canon MF620C over the network, but the scanner did not appear in MF Scan Utility or the scan selector. The printer side and scanner side used separate software paths, so one could work while the other failed.

What was tried: Users checked printer IP address, opened scanner selector, reinstalled MF Scan Utility, checked firewall prompts, restarted router and printer, and tested scanning from another PC.

How this played out: The repair path was network scan registration. Users reinstalled the scanner driver and MF Scan Utility, selected the MF620C network scanner, allowed the scan utility through Windows security prompts, and restarted the scan app. Network scanning returned after the scanner entry matched the active printer IP and scan software path.

Problem: Canon MF620C wireless setup does not complete

What users observed: Users tried to switch the MF620C series printer to wireless LAN, but the computer could not find it or the driver installer did not complete the connection. The MF620 series setup material includes wireless LAN setup, router checking, and driver/software installation as linked setup steps.

What was tried: Users checked the router, changed wireless connection method, restarted the printer and computer, installed the driver/software package, and tested printing after wireless setup.

How this played out: The fix was wireless setup in sequence. Users connected the printer to the wireless network first, confirmed the wireless setting on the printer, installed the driver/software package, and added the printer through the network connection. Printing and scanning became stable after the printer, router, and Canon software all used the same network path.

Problem: Canon MF620C network printer uses the wrong port or old IP address

What users observed: Users saw the MF620C listed in Windows, but print jobs did not reach the machine. This often happened after router changes, wireless reconnects, or Windows creating a stale WSD or old TCP/IP port.

What was tried: Users printed network information, checked the printer IP address, removed and re-added the printer, checked printer properties, restarted the router, and tested another device.

How this played out: The repair path was port correction. Users checked the active printer IP address, removed the stale Canon queue, added the printer again through the current network address, and printed a test page. The print path stabilized after Windows stopped sending jobs to an old network port.

Problem: Canon MF620C toner cartridge is not recognized

What users observed: Users inserted or replaced toner cartridges and the Canon MF620C still showed a cartridge or toner-related state. Windows could show the printer installed, but the device refused to print normally.

What was tried: Users powered the printer off, removed and reseated cartridges, checked packaging material, inspected the cartridge area, closed covers firmly, and restarted.

How this played out: The repair path was cartridge seating and cover-state cleanup. Users reseated each toner cartridge, checked that packaging material was removed, closed the cover firmly, and restarted the printer. The cartridge state cleared after the toner and cover positions were corrected.

Problem: Canon MF620C leaves toner spots or dirty pages

What users observed: Users saw toner spots, dirty marks, smudges, or repeated defects on printed pages. The printer accepted jobs, but the page showed physical toner defects.

What was tried: Users printed several test pages, checked toner cartridges, cleaned accessible toner residue, inspected paper path areas, and tested another cartridge where available.

How this played out: The fix was print-path cleanup. Users cleaned accessible toner residue, reseated toner cartridges, checked paper path areas, and tested another page. Repeated marks stayed with cartridge, drum/imaging, roller, or internal paper-path behavior rather than the Windows driver.

Problem: Canon MF620C paper size or paper type mismatch blocks printing

What users observed: Users sent a print job and the printer stopped because the paper setting did not match the loaded paper. This often appeared when the driver expected a different paper size or type than the tray contained.

What was tried: Users checked paper size in the driver, checked tray paper settings, reloaded paper, changed paper type, restarted the job, and tested a simple document.

How this played out: The repair path was tray and driver setting alignment. Users matched the paper size and paper type in Windows with the paper loaded in the tray, cleared the old job, and printed again. The device resumed after the tray settings and print job settings matched.

Problem: Canon MF620C scanner glass or feeder leaves lines on scans

What users observed: Users could print clean pages, but copies or scans showed lines, marks, shadows, or dirty bands. This pointed toward the scan path rather than the toner or print engine.

What was tried: Users cleaned the flatbed glass, checked the feeder strip, copied from the flatbed, scanned from the computer, and compared print-only pages against copies.

How this played out: The fix was scan-path cleaning. Users cleaned the flatbed glass and feeder scan strip, removed dust or residue, and tested another copy or scan. Scan marks cleared after the glass and feeder path were cleaned, while clean computer prints confirmed that the print engine was not the source.
