Canon PIXMA MG3620 Wireless Setup, Scanner Not Working, Printer Offline, Phone Printing, USB, Missing Black Ink, Cartridge, and Paper Feed Problems

Canon PIXMA MG3620 Wireless Setup, Scanner Not Working, Printer Offline, Phone Printing, USB, Missing Black Ink, Cartridge, and Paper Feed Problems

The Canon PIXMA MG3620 is a wireless inkjet all-in-one printer, so reported problems usually involve wireless setup, Canon PRINT app setup, Windows printing, printer offline status, IJ Scan Utility, scanner detection, phone printing that works while Windows does not, USB fallback, cartridge recognition, missing black ink, blank pages, and paper feed. 

Canon MG3620 wireless setup cannot find the printer

Users reported that wireless setup could not find the Canon MG3620 even though the printer was powered on. This often happened after a router change, Wi-Fi password change, firewall prompt, VPN connection, or failed setup attempt.

In resolved cases, users got wireless setup working again after confirming the computer or phone was on the correct network, disconnecting VPN where needed, allowing local network access, rerunning Canon setup, and adding the printer again. 

Canon MG3620 appears offline after Wi-Fi change

Users reported that the MG3620 showed offline after changing Wi-Fi, restarting the router, or reconnecting the printer. In some cases, Windows troubleshooting brought the printer online temporarily, then it went offline again later.

What worked in resolved cases was clearing Use Printer Offline, restarting Print Spooler, removing duplicate Canon queues, confirming the active network route, and adding the printer again. This belongs with Printer Offline Error and Network Printer IP Address Keeps Changing.

Windows adds the Canon MG3620 but jobs stay stuck

Users reported that Windows listed the MG3620, but jobs stayed in the queue, failed, or disappeared without printing. The printer entry existed, but the queue, driver, wireless route, or spooler state was broken.

In resolved cases, users got printing back after clearing stuck jobs, restarting Print Spooler, selecting the active Canon queue, removing duplicates, and sending one fresh test page. This matched Printer Connected But Not Printing.

Canon MG3620 prints from phone but not Windows

Users reported that the MG3620 printed from a phone or Canon app but not from a Windows PC. That usually proved the printer and Wi-Fi connection were usable, while the Windows computer had a local queue, driver, firewall, VPN, or network-route problem.

What worked in resolved cases was confirming the Windows PC was on the same network, removing stale Canon entries, allowing local printer discovery, restarting Print Spooler, and adding the printer again. The issue cleared after users treated phone printing and Windows printing as separate paths.

Canon software or IJ Scan Utility cannot find the MG3620 scanner

Users reported that the MG3620 printed but did not scan, or that Canon software did not list the scanner. That showed the print route was working while the scanner source or Canon scan software path was missing.

In resolved cases, users repaired or reinstalled the Canon software package, selected the MG3620 scanner source, restarted Windows, and tested one scan from the computer. This belongs with MFP Prints But Does Not Scan.

USB works but Wi-Fi does not

Users reported that the MG3620 worked over USB but not wirelessly. This usually proved the printer and driver could work, while wireless setup, router connection, or Windows wireless queue was wrong.

What worked in resolved cases was removing old wireless queues, reconnecting the printer to Wi-Fi, confirming the Windows computer was on the same network, and adding the printer again through the wireless route. Users had better results after separating USB success from wireless setup failure.

Canon MG3620 will not print black after cartridge change

Users reported that after replacing or refilling the black cartridge, the MG3620 would not print black. In some cases, the nozzle check showed color output but no black pattern.

In resolved cases, users checked cartridge seating, confirmed the cartridge was recognized, printed a nozzle check, ran cleaning only as needed, and tested a black-text document. Cases where the black pattern stayed missing after normal cleaning usually pointed to cartridge, nozzle, or printhead behavior rather than Windows driver setup.

Canon MG3620 cartridge light flashes or ink is not recognized

Users reported cartridge lights flashing, ink not recognized, or printing blocked after cartridge replacement or refill. Windows could still see the printer, but the printer would not accept the cartridge state.

What worked in resolved cases was reseating the cartridge, checking that it was installed in the correct slot, closing the cover firmly, clearing the cartridge state, and testing again. Users got better results after treating this as a printer-side cartridge recognition issue.

Canon MG3620 paper feed or false jam problems

Users reported paper not feeding, pulling crookedly, stopping halfway, or showing jam messages after visible paper was removed. These problems sometimes looked like Windows print failures even though the printer had already received the job.

In resolved cases, users reloaded clean paper, reduced the stack, aligned the guides, removed curled or damp paper, checked the paper path, and tested one page. This belongs with Printer Says Paper Jam But No Paper Is Stuck.
