Question 1

canon pixma mg3620 stop button won't do anything, the light just stays on

Accepted Answer

The Stop button is mainly for canceling print jobs and entering maintenance modes. If a job isn't printing, it might not respond. But if you're trying to use it for cleaning functions and nothing's happening, the printer might be in an error state or not fully ready. First, check the obvious: is there a paper jam? Are the ink cartridges properly installed and not empty? An error condition can make the printer unresponsive to button sequences. If there's no clear error, try a power cycle. Turn the printer off using the power button, wait 30 seconds, and turn it back on. After it fully initializes (ON lamp steady), try the cleaning sequences again. For print head cleaning, you need to hold Stop until the Alarm lamp flashes two times (for standard) or three times (for deep clean) and then release immediately. Holding too long or not long enough won't trigger it. If the button seems physically broken or the printer remains totally unresponsive after a power cycle, there could be a hardware fault. That's a service call.

Question 2

my canon mg3620 printed pages have random ink smudges not from the document, how do i clean it?

Accepted Answer

Ink inside the printer, on the bottom plate. Perform a bottom plate cleaning. From the printer: Power on. Remove all paper. Fold a new A4 or Letter plain paper sheet in half widthwise. Unfold. Fold one side to the center crease. Unfold. Load this single sheet, crease ridges up, the edge of the uncreased half facing the far side. Open output tray extension, open paper output tray, extend support. Hold Stop button until Alarm lamp flashes eight times. Release. The paper feeds through and cleans the interior. Check the ejected paper's creases. If smudged, repeat. From your computer, use the driver: Open printer setup, Maintenance tab, click Bottom Plate Cleaning. Follow the on-screen instructions to fold and load the paper, then click Execute. Do this regularly to prevent smudging. If smudges persist after cleaning, there may be a leak or other fault.

Question 3

can i use generic cleaning sheets for my canon mg3620 paper feed roller?

Accepted Answer

Yes. You can use a cleaning sheet available on the market for paper feed roller cleaning. The procedure is identical whether using a commercial cleaning sheet or a sheet of A4/Letter-sized plain paper. The steps from the printer are: Power on, remove all paper from the front tray. Open the paper output tray. Hold the Stop button until the Alarm lamp flashes seven times, then release. The rollers rotate clean without paper. After rollers stop, close output tray, load one cleaning sheet (or plain paper) into the front tray. Open output tray extension and support. Hold Stop until Alarm flashes seven times again to run cleaning with the sheet, which then ejects. IF THAT DIDN'T WORK: If paper feed problems continue after cleaning, the roller may be worn or the issue may be mechanical. Contact Canon service. HEADS UP: Cleaning wears the paper feed roller, so perform this only when necessary—specifically when paper isn't feeding properly due to dirt or paper particles.

Question 4

canon pixma mg3620 keeps flashing its alarm lamp, what's that mean?

Accepted Answer

Yeah, the flashing Alarm lamp is the printer's way of signaling an error or that it's in a maintenance mode. The pattern tells you exactly what's up. Two flashes means it's doing a standard print head cleaning—you probably held the Stop button. Three flashes means it's in deep cleaning mode. Seven flashes is for cleaning the paper feed roller. Eight flashes means it's running an internal bottom plate clean. If you didn't initiate anything and it's flashing an error, the most common cause is an ink issue. Check the ink status lamps on the operation panel. An empty or incorrectly installed cartridge will trigger an alarm. If the Alarm lamp is flashing and you can't clear it, try turning the printer off and on again. If it persists, check for any paper jams inside, ensure the FINE cartridge holder isn't obstructed (don't touch it while it's moving), and verify all ink cartridges are properly seated and have ink. HEADS UP: Don't try to force-stop or move the FINE cartridge holder. Let it complete its cycle. If the Alarm lamp issue continues with no clear cause (like low ink), a power cycle is your first move.

Question 5

how do you clean the inside of a canon pixma mg3620? it's smudging the backs of my pages

Accepted Answer

You need to perform a bottom plate cleaning. This removes ink from inside the printer to prevent smudges, especially important before duplex (double-sided) printing. Power on the printer and remove all paper from the front tray. Take one new sheet of A4 or Letter-sized plain paper. Fold it in half widthwise, then unfold it. Fold one side of the opened paper in half again, aligning the edge with the center crease, then unfold. Load this single sheet into the front tray with the ridges of the creases facing up and the edge of the half with no crease facing away from you (toward the far side). Open the output tray extension, open the main paper output tray, and extend the paper output support. Press and hold the Stop button until the Alarm lamp flashes eight times, then release immediately. The paper will feed through and clean the interior. After the paper ejects, check the folded crease areas for ink smudges. If they're dirty, repeat the Bottom Plate Cleaning process. For a software-assisted method, you can also use the Bottom Plate Cleaning function in the Maintenance tab of your printer driver.

Question 6

canon mg3620 power light is on but it won't print anything from my computer

Accepted Answer

First, check the printer's wireless connection and your computer's print queue. If those are clear, the issue is likely a clogged print head. Run a standard cleaning cycle directly from the printer. Make sure the printer is on. Press and hold the Stop button until the Alarm lamp flashes twice, then release it. Wait for the ON lamp to stop flashing and stay lit (takes 1-2 minutes). Try printing a test page. IF THAT DIDN'T WORK: If output is still faint or missing, perform a deep cleaning. Hold the Stop button until the Alarm lamp flashes three times, then release. Wait for completion. If the deep cleaning doesn't resolve it, power the printer off (do not unplug), wait 24 hours, and run deep cleaning again. HEADS UP: Cleaning consumes ink. If problems persist after a second deep cleaning and a new FINE cartridge, the print head may be faulty—contact service.

Question 7

canon pixma mg3620 paper isn't feeding right, keeps jamming or misfeeding

Accepted Answer

Dirty paper feed rollers. Perform a roller cleaning. Remove all paper from the front tray. Open the printer driver setup window on your computer. Go to the Maintenance tab and click Roller Cleaning. With the printer on, click OK to start. After the rollers stop, load one sheet of plain paper or a commercial cleaning sheet into the front tray as prompted and click OK. The sheet will eject, completing the cycle. If that fails, clean the rollers directly from the printer. Power on, remove paper, open the paper output tray. Hold the Stop button until the Alarm lamp flashes seven times and release. Wait for rollers to stop. Close the output tray, load a single A4 or Letter plain/cleaning sheet. Open the output tray and its extension, extend the support. Hold Stop until Alarm flashes seven times again to run cleaning with paper. If paper still doesn't feed, contact service. Cleaning wears the rollers, so only do it when needed.

Question 8

my canon pixma mg3620 is printing with faded colors and missing lines, how do i fix this?

Accepted Answer

The most likely cause is clogged print head nozzles. The first step is to perform a standard print head cleaning. Ensure the printer power is on. Press and hold the Stop button until the Alarm lamp flashes two times, then release immediately. Wait 1-2 minutes for the cleaning to finish, indicated by the ON lamp lighting after flashing. Do not operate the printer during this time. After cleaning, print a nozzle check pattern to verify the result. IF THAT DIDN'T WORK: If print quality doesn't improve, perform a deep cleaning. Hold the Stop button until the Alarm lamp flashes three times, then release. Wait 1-2 minutes for completion and check with another nozzle pattern. If the problem persists after deep cleaning, turn the printer off (do not unplug it), wait 24 hours, and perform deep cleaning again. If issues remain after the second deep cleaning, the FINE cartridge may need replacement. HEADS UP: Both cleaning methods consume ink, so only perform them when necessary. If the problem continues after replacing the FINE cartridge, contact Canon service.

Question 9

canon pixma mg3620 wireless setup is a pain, i never got the cloud printing email to register. what gives?

Accepted Answer

The registration email can get caught in spam filters or just take a minute. If you never got it, you can't finish setting up the Canon Inkjet Cloud Printing Center. First, check your spam or junk mail folder for an email from Canon with a URL link. If it's there, click the link. You'll need to agree to the license and privacy statements, then register a password. If that didn't work: The email might have been sent to the wrong address. Double-check the email you entered during setup. If it's wrong, you'll need to start the registration process over. Also, the service requires an Administrator. That's usually the first person who registers. If you're trying to add users (like family members), the Administrator has to do it from the 'Manage users' screen inside the Cloud Printing Center. They select 'Add user' and follow the prompts. Heads up: You can't delete yourself as a user from the 'Manage users' screen. To do that, you have to cancel your membership from the 'My account' screen.

Question 10

can i clean the glass scanner part on my mg3620? it has fingerprints and dust.

Accepted Answer

Absolutely, you can clean the platen glass (the scanner glass). You just need to be gentle. Here's how:Make sure the printer is turned off and unplugged. Lift the document cover. Use a soft, dry cloth—like the kind for cleaning eyeglasses. Smooth out any wrinkles in the cloth first. Wipe the glass surface gently to remove dust and fingerprints. Don't press hard. Do not use any liquids, window cleaners, or abrasive cloths. You could damage the surface or leave streaks. That should take care of it. The same method works for cleaning the exterior plastic of the machine if it gets dusty.

Question 11

my canon pixma mg3620 is making a weird grinding noise when i try to print, should i be worried?

Accepted Answer

A grinding noise usually means a mechanical obstruction. Stop printing immediately. Power off the printer. Inspect for a paper jam. Remove all paper from the front tray. Look inside for any torn scraps or foreign objects. Check the FINE cartridge holder area. Do not touch or force it. Ensure cartridges are seated correctly. Power back on. Listen if the noise recurs during startup. If that didn't work: The noise could be from the paper feed rollers trying to grip without paper during a cleaning cycle. If you initiated a roller cleaning (Alarm lamp flashes seven times), let it complete. The rollers will spin and then stop. Do not interrupt. Heads up: Never hold the FINE cartridge holder to stop or move it forcibly. Do not touch it until it stops completely. If the noise persists with no jam found, a component may be damaged—contact service.

Question 12

Accepted Answer

Yes, dirty paper feed rollers are the culprit. Clean them. From the printer:Power on. Remove all paper from the front tray. Open the paper output tray. Hold the Stop button until the Alarm lamp flashes seven times, release. The rollers will spin clean. Once they stop, close the output tray, load one sheet of plain A4 or Letter paper (or a store-bought cleaning sheet) into the front tray. Open the output tray extension and support. Hold the Stop button until the Alarm lamp flashes seven times again, release. The page will eject, completing the clean. From your computer:Open the printer driver setup window. Go to the Maintenance tab, click 'Roller Cleaning'. Follow the on-screen prompts: remove all paper first, then load a single sheet when instructed. If that didn't work: Check for tiny paper scraps stuck inside. If the problem continues after cleaning, the rollers may be worn out—contact service. Heads up: This cleaning wears the rollers a bit, so only do it when necessary.

Question 14

canon pixma mg3620 printing blurry or with streaks, lines are missing. how do i fix this?

Accepted Answer

You've got a clogged print head. It happens, especially if the printer hasn't been used in a while. Here's how to clear it up. First, try a standard cleaning from the printer itself: Make sure the power is on. Hold down the Stop button until the orange Alarm lamp flashes two times, then let go. The machine will start cleaning. Just wait—it takes about a minute or two. You'll know it's done when the white ON lamp lights up after flashing. After cleaning, print a nozzle check pattern to see if the streaks are gone. If that didn't work: The clog might be stubborn. You need a deep cleaning. The process is almost the same, but you hold the Stop button until the Alarm lamp flashes three times, then release. Wait another 1-2 minutes for it to finish. If the problem still isn't fixed after a deep cleaning, turn the power off, wait 24 hours, and try the deep cleaning one more time. Don't unplug the cord when turning it off. If streaks persist after that, it's probably time for a new FINE cartridge.

Question 15

my canon pixma mg3620 keeps flashing the orange alarm light and won't print anything, what does that mean?

Accepted Answer

The orange Alarm lamp flashing indicates a printer error, most likely an ink issue or a paper jam. Check the ink status lamps on the operation panel. If one is flashing or off, that cartridge is low or empty. Replace it. Clear any jammed paper. Turn the printer off, remove all paper from the front tray, check inside for scraps, then power it back on. If the Alarm lamp flashes during a cleaning cycle (two flashes for standard cleaning, three for deep cleaning), wait. The ON lamp will light solid when it's done. Do not touch the FINE cartridge holder or perform other operations until it stops. If that didn't work: The print head might be clogged. Try a standard print head cleaning. With the power on, hold down the Stop button until the Alarm lamp flashes twice, then release. Wait 1-2 minutes for it to finish. Print a nozzle check pattern to see if quality improves. Heads up: Forcing the FINE cartridge holder to stop can damage the printer. Let all movements complete on their own.

Question 16

can i use my canon mg3620 wirelessly without installing the cloud printing center stuff?

Accepted Answer

Yes, the Canon Inkjet Cloud Printing Center is a specific service for remote printing and app management. Standard wireless printing to your home network does not require it. For basic wireless printing: Connect the printer to your Wi-Fi network using the standard setup process (WPS button or via USB during initial driver installation). Install the standard Canon printer drivers on your computer or mobile device. You can then print directly over your local network. The Cloud Printing Center is only needed if you want features like: - Printing from anywhere over the internet. - Setting up multiple users (Administrator/Standard) for one printer. - Limiting which apps (like Evernote, Facebook) specific users or groups can access from the printer. Heads up: If you are trying to use the Cloud Printing Center and didn't get a registration email, check your spam folder and ensure you entered the correct email address during printer setup.

Question 17

canon pixma mg3620 making a weird grinding noise when i try to print, is it broken?

Accepted Answer

Unusual noise during operation often points to a mechanical obstruction or a dirty feed mechanism. Stop printing immediately. First, power off the printer and inspect for any obvious obstructions like jammed paper fragments. Clear any debris. If the noise seems related to paper feeding, the paper feed rollers likely need cleaning. Follow the paper feed roller cleaning procedure: remove all paper, open the output tray, hold Stop until the Alarm lamp flashes seven times. After the rollers stop, load a single sheet of plain paper, hold Stop for seven flashes again to complete the cleaning cycle. If that didn't work: If the noise persists after cleaning and no jam is present, a internal component may be damaged. Do not hold or force the FINE cartridge holder. Contact Canon service. Heads up: Forcing the mechanism can cause serious damage.

Question 18

how do i clean the scanner glass on my canon mg3620 all-in-one?

Accepted Answer

Use a soft, dry cloth. An eyeglasses cleaning cloth is ideal. Procedure: Ensure the cloth is smooth, without wrinkles. Gently wipe the platen glass (scanner bed) and the inside of the document cover to remove dust or smudges. Do not use liquids or abrasive cleaners.

Question 19

canon pixma mg3620 print head cleaning not working, lines still missing after i tried it

Accepted Answer

Yeah, the standard clean doesn't always cut it for a stubborn clog. You need to escalate to a deep clean, then give it a full day to rest if that fails. First, run a Deep Cleaning. On the printer itself, make sure it's on, then hold down the Stop button until the Alarm lamp flashes three times and let go. Wait for the ON lamp to settle (about 2 minutes). Then print a test page. If the lines are still there, here's the critical step: turn the printer power off. Do not unplug it. Leave it completely off for 24 hours. This lets ink re-saturate the dried nozzles. After a full day, power it back on and run the Deep Cleaning procedure (three flashes) again. If that didn't work: If it's still printing poorly after the second deep clean, the FINE cartridge itself is probably the issue and needs to be replaced with a new one. If a new cartridge doesn't fix it, it's time to contact the service center.

Question 20

my canon pixma mg3620 is smudging the back of pages when i print double-sided, how do i clean it?

Accepted Answer

Ink has built up on the bottom plate inside the printer. You need to run a bottom plate cleaning cycle before duplex printing. Here's how: On your computer, open the printer driver setup window and go to the Maintenance tab. Click Bottom Plate Cleaning. A dialog box will open with instructions. Prepare a single sheet of new A4 or Letter-sized plain paper. Fold it in half horizontally, then unfold it. Fold one side of the paper in half again, aligning the edge with the center crease, then unfold it. Load this single sheet into the front tray with the ridges of the creases facing up. The edge of the half with no crease should face away from you. Make sure the printer is on, then click Execute in the dialog box. The printer will feed the specially folded paper through to clean the inside. If that didn't work: After the page ejects, check the folded parts for ink smudges. If they are dirty, run the Bottom Plate Cleaning procedure again.

Question 21

canon mg3620 alarm light flashing and won't print, what does that mean?

Accepted Answer

The Alarm lamp flash pattern indicates a specific maintenance function or error. Count the flashes. Two flashes (hold Stop button): Initiates standard print head cleaning. Three flashes (hold Stop button): Initiates deep print head cleaning. Seven flashes (hold Stop button): Initiates paper feed roller cleaning. Eight flashes (hold Stop button): Initiates bottom plate (inside) cleaning. If that didn't work: If the lamp is flashing in a pattern not listed here, check the ink status lamps. An ink cartridge may be empty or incorrectly installed. Heads up: During any cleaning cycle (1-2 minutes), do not perform other operations or touch the FINE cartridge holder until it stops completely.

Question 22

canon pixma mg3620 paper feed roller not grabbing paper properly, what should i do?

Accepted Answer

Dirt or paper particles are stuck to the feed rollers. Clean them. First, remove all paper from the front tray. Open the paper output tray. Hold down the Stop button until the Alarm lamp flashes seven times, then release. The rollers will rotate to clean themselves. After they stop, close the output tray. Load one sheet of A4 or Letter-sized plain paper (or a commercial cleaning sheet) into the front tray. Open the output tray and its extension. Hold down the Stop button until the Alarm lamp flashes seven times again and release. The printer will feed and eject the paper, completing the cleaning. If that didn't work: If paper still doesn't feed after cleaning, the rollers may be worn. Contact Canon service. Heads up: This cleaning wears the rollers. Only perform it when necessary.

Question 23

my canon pixma mg3620 is printing with faint streaks and missing lines, how do i fix this?

Accepted Answer

The print head nozzles are clogged. You need to run a cleaning cycle. From the printer itself: Make sure the power is on. Hold down the Stop button until the Alarm lamp flashes twice, then release it immediately. Wait for the ON lamp to stop flashing and stay lit (about 1-2 minutes). Do not touch anything during this time. After cleaning, print a nozzle check pattern to see if the streaks are gone. If the print quality is still poor, you need to run a Deep Cleaning from the printer driver on your computer. If that didn't work: If standard cleaning doesn't resolve it, perform a Deep Cleaning. On the printer, hold down the Stop button until the Alarm lamp flashes three times, then release. Wait for the ON lamp to stabilize. Deep cleaning uses more ink, so only do it if necessary. Heads up: If the problem persists after a deep cleaning, turn the printer off (do not unplug it) for 24 hours, then run deep cleaning again. If it still fails, the FINE cartridge likely needs replacement.
