Replacing Ink and Network Setup for Canon TR4720
The Canon TR4720 is a compact all-in-one designed for home and small-office use, but routine tasks like replacing ink and connecting the printer to a wireless network can feel daunting if you haven’t done them recently. This guide focuses on practical, step-by-step information to help you complete two of the most common workflows: ink replacement and network setup. Both tasks affect ongoing print quality and the reliability of scanning and mobile printing, so understanding how cartridges fit, how to install them correctly, and how to get the TR4720 on your Wi‑Fi will save time and avoid avoidable errors. The instructions below avoid unnecessary technical jargon and point out common traps—such as tape on a new cartridge or weak Wi‑Fi signal—that often cause people to call support unnecessarily.
Which ink cartridges does the Canon TR4720 use and what should you buy?
Before you start a Canon TR4720 ink replacement, confirm the cartridge model your printer requires. The TR4720 is compatible with Canon’s PG-245 (black) and CL-246 (color) series; both series are commonly available in standard and high-yield (XL) sizes. You can use genuine Canon PG-245/CL-246 or XL equivalents, and many third-party inks claim compatibility—choose reputable sellers and verify return policies. Replacement ink cartridges matter for print longevity and color accuracy: genuine cartridges typically include a chip that communicates ink levels to the printer, while remanufactured cartridges can work but may produce inconsistent “ink level” readings. Below is a quick reference for the commonly used cartridges for this model.
| Cartridge | Color | Available Sizes |
|---|---|---|
| PG-245 / PG-245 XL | Black | Standard, High-yield (XL) |
| CL-246 / CL-246 XL | Color (Cyan/Magenta/Yellow) | Standard, High-yield (XL) |
How to replace ink cartridges on the Canon TR4720 — step by step
Performing a Canon TR4720 ink replacement is straightforward if you follow a few precautions. Start with the printer powered on so the carriage can move to the access position. Open the front cover and wait for the cartridge holder to stop. Remove the old cartridge by pressing it down gently (or pressing its release tab) and pulling it out toward you. For a new cartridge, remove protective tape and any plastic packaging—do not touch the electrical contacts or print head nozzles. Insert the cartridge into the correct slot (black in the black slot, color in the tri-color slot) and press it until it clicks into place. Close the cover. After replacement, the printer may run a short initialization routine and perform an automatic nozzle check; if print quality looks off, run a cleaning cycle from the maintenance menu. If the printer still shows an “ink low” or “replace” alert despite a new cartridge, consult the TR4720 manual or the printer software for an ink-level reset procedure or firmware update.
How to set up Wi‑Fi and add the TR4720 to your network
Connecting the Canon TR4720 to a wireless network gives you the flexibility to print from laptops, smartphones, and cloud services. There are three common methods: using the printer’s wireless setup wizard, using WPS (if your router supports it), or using the Canon PRINT Inkjet/SELPHY app on a mobile device. For the setup wizard, power on the printer, open the Settings or Network menu on the printer’s display, choose Wireless LAN setup, select your SSID (network name), and enter your Wi‑Fi password. For WPS, press the WPS button on your router and then follow the printer’s WPS procedure—this can be faster but only works when your router supports the push-button WPS mode. The Canon PRINT app can guide you step-by-step and automatically install printer drivers on many devices. If the printer fails to connect, check that the router is broadcasting on a 2.4 GHz band (many Canon models prefer 2.4 GHz over 5 GHz for range), verify the password, and ensure any MAC filtering or router firewall settings aren’t blocking new devices.
Troubleshooting common ink recognition and network problems
Two issues show up most frequently for TR4720 owners: cartridges not being recognized and intermittent Wi‑Fi. For cartridge recognition problems, first re-seat the cartridge and make sure protective tape over the contacts is removed. Clean contacts gently with a lint-free cloth if necessary, and avoid third-party cartridges that report poor compatibility. For persistent “cartridge not recognized,” a firmware update may resolve communication issues—check the printer software or Canon’s official update tool. For network problems, restart both router and printer, move the router closer if the signal is weak, and temporarily disable complicated network features such as guest networks or VPNs during setup. If the printer connects but loses the connection intermittently, assigning a static IP address via the router’s DHCP reservation can stabilize the link. Reinstalling the Canon driver and using the printer’s troubleshoot diagnostics from the device settings will often reveal specific error codes and recommended fixes.
Replacing ink and setting up a wireless connection on the Canon TR4720 are tasks most users can complete quickly with a bit of preparation: keep the correct cartridges on hand, handle cartridges by the body (not the contacts), and choose the easiest wireless setup method your router supports. Regular maintenance—running nozzle checks, keeping firmware current, and placing the printer where it receives a reliable Wi‑Fi signal—reduces the chance of repeat issues. For step-specific instructions or unusual error codes, refer to the TR4720 manual and Canon support resources; they provide the manufacturer-verified procedures and firmware downloads that match your exact model and region.
