The First Test Page
The box arrived in late January 2025. That morning, I was sure I'd have the Canon TS3722 up and running before lunch. The small online fitness-brand shop I run needed a reliable all-in-one, since we sell printed workout cards and instruction labels. One of the free tools on our site is a bench press calculator that estimates one-rep max, and we wanted to turn those estimates into printable cards. That little dream hit a lot of friction.
I unpacked the printer, installed the ink cartridges, loaded a stack of copy paper, and followed the front panel prompts. The first test page came out in maybe thirty seconds. Text looked sharp. Colors looked fine. I closed the box and told myself the hard part is over. That was optimistic.
The WiFi Rabbit Hole
The hard part started when I unplugged the USB cable. I opened the Canon app, chose the wireless option, waited for the app to find the printer, and then watched the setup fail for reasons the error message did not explain. My first instinct was to type 'how to connect canon ts3722 printer to wifi' into a search engine. I read more than a few pages. Somewhere in that browsing session, I typed 'canon-printer' with a hyphen, as if the URL had told me to. It didn't help.
The official instructions looked simple: press the wireless button, press the router's WPS button, wait. But I kept pressing the WPS button on the printer itself instead of the wireless button. The printer would enter the wrong mode, and the connection would fail. At one point I thought the printer had a dead WiFi radio. Honestly, the only dead thing was the button-pressing sequence between my ears.
The Parts Mistake
While I was still pretending the WiFi issue was something I could solve by looking at hardware, I noticed the draft print quality looked faded. The printer also warned about maintenance ink. Instead of reading the manual, I started hunting for replacement parts. I typed 'canon printer parts online' and ended up on a marketplace site with a cheaper maintenance cartridge. I ordered it. It was the wrong variant for the TS3722. The printer refused to acknowledge it and lit up with an orange warning. I spent the next hour resetting the machine and then searching for a way to cancel my order.
If you need parts, my advice after this mistake: use the exact model number and check whether the seller is an authorized source. The phrase 'canon printer parts online' is too broad. The phrase 'TS3722 maintenance cartridge official' is better.
The Permanent Marker Regret
While unpacking the wrong cartridge to prepare a return label, I grabbed a permanent marker and wrote 'return' on the box. The marker worked fine. Then I left the marker lying on the top of the printer. It rolled and dragged a black line across the plastic panel above the paper output. I stared at it for a moment, hoping the ink would suddenly soak in or disappear. It didn't. I finally looked up 'how to remove permanent marker' and learned that isopropyl alcohol works on most surfaces, including printer plastic. A cotton swab and a bit of patience did the trick. Still, the lesson is real: keep a sticky note or painter's tape near the machine, not a permanent marker.
It Restarts Mid-Job
With the printer still connected by USB, I thought I could at least finish my printables. But then it started a new act: it would restart in the middle of longer jobs. I remember watching a bench press calculator card stop at fifty percent and the TS3722 power-cycle itself. The paper sat in the output tray with an unfinished print. Not ideal.
Since I'm not an electrician, I didn't want to guess about power problems. But I did want to know if the long extension cord was the culprit. I used a voltage drop calculator with the cord length, wire gauge, and the printer's rated current. The resulting voltage drop was noticeable but not crazy. The real problem was the space heater on the same power strip, drawing a big burst whenever it kicked on. The printer needed clean power. I moved the TS3722 to its own wall outlet and the resets stopped.
The Fix That Was Always Simple
After the power fix, I finally called the support number. The person on the other end asked, 'Does your router have a WPS button?' It did. He told me to press and hold the wireless button on the TS3722 until the WiFi lamp started flashing, then press the WPS button on the router within two minutes. I waited. The connection indicator went solid. That was the whole fix. No PIN, no setup disc, no hidden secret menu.
To celebrate, I printed that bench press calculator card again, this time wirelessly. It came out clean on 100 lb cover stock at 300 DPI. That resolution is the practical standard for small-format cards that people hold in their hands. Draft mode at a lower resolution looked fine on the screen, but weak on paper. The printer was never the main issue. I was just giving it the wrong instructions.
What I'd Tell Someone Else
If you just bought a Canon TS3722, here are the lessons I wish I had read before opening the box:
- Try WPS first. Press and hold the wireless button on the printer until the light flashes, then press the WPS button on the router within two minutes.
- When you need replacements, search with the exact model number. 'Canon printer parts online' is a starting point, not a plan.
- Don't put a permanent marker anywhere near the printer. You will inevitably regret it.
- If the printer restarts mid-job, test a different outlet before ordering anything. A voltage drop calculator can help, but a wall outlet test is faster.
One more thing. I was a small customer on a support call, and I didn't feel like a small deal. The person on the phone treated the problem like a real problem. That stayed with me. Today's little order may be tomorrow's bigger one, but even if it never grows, it still deserves the same basic respect. Small problems respond well to clear thinking. The printer just needs the right buttons in the right order. The rest is patience, a little bit of alcohol, and a sticky note instead of a permanent marker.
