Canon MG3620 Drivers, Paper Feed & Blurry Print Issues
Canon MG3620 Drivers, Paper Feed & Blurry Print Issues
This page exists because many Canon PIXMA MG3620 failures initially appear to be driver or setup issues. The printer powers on, responds to jobs, and may even print correctly in certain modes — yet feeding fails, WiFi drops repeatedly, or output becomes distorted. In reported cases, reinstalling drivers did not change the behavior. The patterns below reflect what actually affected the outcome.
Problem: Paper feed rollers spin but do not pull paper
What users observed: The printer accepts a job, and the internal rollers attempt to grab the top sheet, but they “burn out” or slip without pulling the paper through. Sometimes, manually assisting the sheet allows a single page to print.
What was tried: Cleaning the rubber feed rollers with alcohol was suggested. Reinstalling drivers was attempted in order to rule out a software mismatch.
How this played out: Driver changes did not affect feeding behavior. Cleaning the rollers did not consistently restore normal pickup. The slipping remained mechanical in nature.
Problem: Grinding/slipping gear noise followed by a paper jam
What users observed: A loud plastic grinding or ratcheting sound during printing, followed by paper crumpling inside the feed path. In some cases, a visible rack/gear mechanism appeared to bind and block the paper path.
What was suggested: Inspecting for debris lodged in the gear train, as well as confirming no internal obstruction preventing carriage or feed movement, are some of the suggested fixes.
Where this sometimes ended: The grinding persisted despite restarts. In several cases, the failure was considered a mechanical gear issue rather than a recoverable software fault.
Problem: Blurry or double-letter printing (ghosting) in standard mode
What users observed: Text appears doubled or blurred. Alignment procedures do not correct it. One consistent detail: switching print quality to High produces clean output, while Standard quality continues to ghost.
What was suggested: Replacing the black cartridge (printhead-integrated cartridge) and testing with genuine/OEM cartridge if using third-party ink was attempted.
How this played out: Reinstalling drivers did not affect the issue. High-quality mode masking the defect pointed toward cartridge or carriage-position feedback behavior rather than alignment software failure.
Problem: Jagged black while color test prints look normal
What users observed: Straight black lines print rough or jagged, while CMYK alignment tests appear normal.
What was suggested: Cleaning the encoder strip carefully using isopropyl alcohol and thoroughly inspecting the encoder strip tension and mounting was suggested.
Where this sometimes ended: The distortion pattern was treated as positioning feedback irregularity rather than ink starvation. Driver reinstall attempts did not change the output pattern.
Problem: Alternating orange/green lights; carriage will not move
What users observed: The printer enters an error loop with alternating indicator lights. The cartridge holder appears blocked or fails to return to its home position.
What was tried: Users suggested removing and reseating the cartridges firmly, ensuring proper lock engagement.
How this played out: In cases where an unseen sheet or obstruction was cleared, and cartridges were reseated, normal operation resumed. The behavior was not tied to driver installation.
Problem: WiFi setup fails after router upgrade; printer not visible on network
What users observed: After changing routers or upgrading equipment, the MG3620 does not appear during setup. The installation fails at the final step. Repeating the WiFi button and Color button sequence does not complete the connection.
How this played out: Adjusting router security from WPA3 to WPA2 resolved the connection, where driver reinstall attempts did not.
The Canon PIXMA MG3620 frequently appears functional while failing in specific mechanical or network-dependent ways. Across reported cases, reinstalling drivers rarely changed the outcome. Feeding failures, grinding sounds, ghosted output, encoder-strip distortion, and WPA3 incompatibility all presented independently of software reinstall attempts.
