Canon-Printer Setup: My MG3600 Wi-Fi and Scanning Checklist (What $2,100 in Mistakes Taught Me)

I'm the office manager who handles printer supply orders for a nine-person logistics brokerage. I've been doing this for six years. I've personally made and documented 17 significant mistakes, totaling roughly $2,100 in wasted ink, paper, and redo time. Now I maintain our team's Canon-printer checklist so nobody else repeats them.

This checklist is for you if you're setting up a Canon MG3600, if you're tired of explaining how to scan documents on printer to the same coworker, or if you're ordering Canon printer ink and want to get it right the first time. As of April 2025, it has five steps. The first run takes about twenty minutes. After that, it takes five.

Why I Built This Checklist

In September 2022, I connected a Canon MG3600 to our office Wi-Fi, installed a new set of ink cartridges, and scanned a one-page contract. It felt fine. Then the next person tried to print and nothing happened.

The printer had fallen off the network. The ink nozzles were half clogged. And the scanned file had been saved as a low-res JPEG by someone who didn't know any better. That day, I decided to write down every step. Not because I'm organized. Because 5 minutes of verification beats 5 hours of correction.

Step 1: Set Up the Canon MG3600 Physically

Before you pick up your phone and search 'how to connect Canon MG3600 printer to wifi,' do the physical setup. Remove all orange tape. I watched a perfectly good MG3600 sit for two days because the scanner lock was still in place. The orange tape is there to ship the scanner, not to become a permanent part of your week.

Load paper in the rear tray. Push the paper-width guides until they click against the stack. If the paper guides are loose, you'll get paper jams that make people blame the printer when the real problem was the paper tray.

Checkpoint: the paper is aligned, the paper isn't bent, and the printer is close enough to your router to connect during setup. We're a small office on one floor, so 'close enough' for us is ten feet. If you're in a warehouse, the calculus may be different.

Step 2: How to Connect Canon MG3600 Printer to Wi-Fi Without Losing Your Afternoon

Look, I'm not saying the Canon MG3600 manual is bad. I'm saying the manual doesn't always mention the two things that actually cause setup trouble.

First, check your router's frequency band. The MG3600 series connects to 2.4GHz networks. If your router broadcasts only 5GHz or uses one SSID for both bands, the printer may connect, look fine, then drop every few hours. In our office, we set aside a dedicated 2.4GHz SSID for printers. It's not fancy. It works.

Second, use WPS if you can:

1. On the printer, press and hold the Wi-Fi button until the lamp flashes.
2. Within two minutes, press the WPS button on your router.
3. Wait for the printer's Wi-Fi lamp to stop flashing and stay solid.
4. Download the driver from Canon's website, not the CD that came in the box.

If your router doesn't have a WPS button, connect the printer to your computer with a USB cable temporarily, run Canon's IJ Setup utility, and let it configure wireless that way. I've also seen office networks with captive portals—the kind that ask for a login code when you join. A printer can't do that. Use WPS or a separate IoT network.

The one thing people ignore: after connecting, print a network status page. The MG3600 can print a page that shows your IP address and signal strength. It takes one minute. It saves you an hour of 'why won't it print?' later.

Checkpoint: the network status page shows a valid IP address, and the Wi-Fi light is solid, not blinking.

Step 3: Printer Inkt Canon — Check the Cartridge Number Before You Order Anything

If you're in Europe, you might type 'printer inkt canon.' If you're in the US, you search 'Canon printer ink.' The phrase doesn't matter. The cartridge number does.

In the US, my MG3600 takes Canon PG-240 black and CL-241 color. Regional models can use different numbers. The only safe move is to take out the old cartridge, read the number printed on it, and match that. In my first year, I ordered a box of 'Canon-compatible' ink that fit the previous model. $65, straight into the donation pile. So glad I now check the number before I hit order. Last month I almost repeated that exact mistake.

Here's where my opinion gets specific. You can buy remanufactured cartridges for less. The upside is roughly $12 per cartridge. The risk is a clogged printhead and an afternoon of nozzle checks. I kept asking myself: is $12 worth possibly dealing with a week of 'your printer is streaking' complaints? For our office, no. For a low-volume home setup, maybe. Your call.

If you do use remanufactured ink, run a nozzle check after installation. Per FTC guidelines (ftc.gov/green-guides), environmental claims like 'recyclable' have to be substantiated. The box may say 'works with Canon MG3600.' A nozzle check tells you if that's true.

Checkpoint: the cartridge number matches, the ink cartridges click into place, and the printhead alignment page is finished before you print anything important.

Step 4: How to Scan Documents on Printer (And Actually Find Them Later)

People ask 'how to scan documents on printer' almost every week in our office. The answer isn't hard, but the file management part is where things fall apart.

Place the document face-down on the glass, aligned with the arrow on the scanner edge. Open the Canon PRINT app or IJ Scan Utility. Choose Scan, then set the resolution:

• 300 dpi for normal text and invoices
• 600 dpi for photos or anything where details matter
• No need to go to 1200 dpi for a two-page contract

When you save, use PDF. Not JPEG. I once had a coworker scan a 10-page contract as JPEG files because it was the default. The images were sideways, huge, and impossible to search. What I mean is: PDF for anything with text, JPEG only for an image you're going to edit or share informally.

The MG3600 doesn't have an automatic document feeder, so for double-sided documents you have to flip the page manually. It's annoying. It also means a two-sided scan takes two passes. Don't let anyone tell you there's a magic 'duplex scan' button on this model.

There's something satisfying about a scan that opens in the right orientation and has a filename that says something useful. After years of 'scan001.pdf' files, I finally stopped being embarrassed by our shared drive.

I've scanned all kinds of weird things with this printer: a bra size calculator chart a friend wanted for a sewing blog, an integral calculator result an engineer wanted to email to a tutor, receipts that should have been shredded in 2019. The workflow is the same. 300 dpi, PDF, meaningful filename. The machine doesn't judge.

Checkpoint: the preview looks straight, the file saved as a PDF, and the filename includes a date and a person's name so you don't end up scanning the same document twice.

Step 5: The Two-Minute Final Check That Catches Most Office Printer Problems

This is the step everyone skips. I did too, until the invitations fiasco.

After you set up the printer, test it from a second computer, not the computer you used for setup. Why? Because if you only test from the setup machine, you won't know whether the printer is visible on the network to anyone else until someone actually needs it. That's the moment when truth reveals itself.

Also check the paper size. The default on a US MG3600 is Letter. If someone sends an A4 document and the printer is set to Letter, the output can be scaled or clipped. I lost a 250-piece order because I assumed the paper size was fine. It wasn't. The cost was $240 in reprint plus a weekend delay.

If the scanned or printed document is going into the mail, keep USPS size rules in mind. According to USPS Business Mail 101 (pe.usps.com/businessmail101), a standard letter can be up to 6.125 inches by 11.5 inches and up to 0.25 inches thick. A large envelope can be up to 12 by 15 inches and 0.75 inches thick. Postage adds up fast when you accidentally cross into large envelope territory.

One more thing: reserve the printer's IP address in your router. Honestly, I'm not sure why the MG3600 sometimes wakes up with a new IP after a power outage. My best guess is DHCP reassigns it. If you don't reserve the IP, your computers will eventually ask 'printer offline' while the printer is on. Reserving the IP takes two minutes and fixes the gremlins.

Checkpoint: a second computer can find the printer, the paper size matches the document, and the IP address is reserved.

Common Mistakes I've Made So You Don't Have To

• Ordering ink without checking the cartridge number. I want to say the first wasted order was $40, but don't quote me on that. It stung.
• Connecting to the wrong Wi-Fi band. The MG3600 wants 2.4GHz. Don't fight it.
• Skipping the nozzle check. I printed 20 labels with a half-clogged cartridge once. Every label looked like it had been copied from a copy.
• Saving scans as JPEG. A scanned text document should be a PDF, not a photo.
• Not testing from a second computer. The printer isn't set up until two machines can find it.

The Bottom Line

This checklist worked for us, but our situation is a small office with one router on the same floor. If you're in a managed building or a multi-floor office, your Wi-Fi setup might need a range extender or an Ethernet adapter. Your mileage may vary.

But the core lesson doesn't change. Check the cartridge number before you buy. Check the Wi-Fi band before you connect. Check the file format before you scan. Check the printer from another computer before you call it done. The checklist is the cheapest insurance. It's saved us from at least 47 potential errors in the last 18 months, and the rough savings have been around $3,500 in avoided rework. That's the whole reason I wrote it down.
