Common “Not Printing” and Printing Quality Issues & Solutions

If your Canon Pixma TR4720 printer is not printing or you are experiencing unsatisfactory print results, consider the following troubleshooting steps:

1. Initial Checks for Printer Operation:

• Power Status: Ensure the printer is turned on. The ON lamp should be lit and not flashing. If it’s flashing, the printer might be initializing or processing data.
• Connections:
  • USB Connection: Verify the USB cable is securely connected to both the printer and the computer. If a USB hub or relay device is used, try connecting the printer directly to the computer to rule out issues with the relay device. You might also need to replace the USB cable.
  • Wi-Fi Connection: Make sure the printer is properly connected to your wireless network. You may need to set up the printer again if you’ve purchased a new computer or wireless router, changed router settings, or forgotten the printer’s administrator password.
  • For wireless direct connections, note that the printer supports a maximum of 5 connected devices.
• Printer Driver & Print Jobs:
  • Ensure the correct Canon printer driver for your model (“Canon XXX series”) is selected in the print dialog box when printing from a computer.
  • Delete any unnecessary print jobs from the print queue on your computer. Restarting your computer can also help resolve printing issues.
  • If you encounter errors like “Could not spool successfully due to insufficient disk space” or “insufficient memory,” free up disk space or close other applications. For “Printer driver could not be found,” uninstall and reinstall the MP Drivers.

2. Ink-Related Problems:

• Ink Levels: Check the estimated ink levels in your FINE cartridges. If a cartridge is empty or low, replace it with a new one. Note that some warnings or errors related to ink levels may prevent printing or scanning.
• Cartridge Installation: Ensure the FINE cartridges are installed properly. If they are not secure, ink may not eject correctly. Push up the ink cartridge lock lever until it clicks into place. Check for any remaining orange tape on the cartridges and remove it before installation.
• Print Head Nozzles: If ink does not come out or printouts are blank, blurry, or have streaks/lines, the print head nozzles might be clogged.
  • Print the nozzle check pattern to confirm the condition of the print head nozzles. If the pattern is incorrect, proceed to cleaning.
  • Perform print head cleaning (takes about 1 minute). If the issue persists after two regular cleanings, perform deep print head cleaning.
  • If deep cleaning twice doesn’t resolve the issue, and you’ve waited 24 hours between cleanings (without unplugging the power cord), the FINE cartridge may be damaged and needs replacement.

3. Paper-Related Problems:

• Paper Jams: If paper is jammed, follow specific instructions to remove it from the paper output slot, front tray feed slot, or from inside/rear of the printer. Always pull jammed paper out slowly with both hands to avoid tearing it. If the printer was turned off to clear a jam, all print jobs in the queue will be canceled, and you’ll need to redo the printing.
• Paper Feed Issues / “No Paper” Error: If the printer doesn’t pick up or feed paper, or gives a “no paper” error, ensure that the paper type and size settings match the loaded paper.
  • Correct any curled or wrinkled paper before loading.
  • If multiple sheets of plain paper are fed, enable the setting for preventing double-feed temporarily, and disable it after printing.
  • Consider cleaning the paper feed rollers if problems persist, but note that this can abrade them, so do it only when necessary.
• Paper Output Cover/Tray: Ensure the paper output cover is closed and the paper output tray is open, with the support and extension pulled out, for proper printing.

4. Print Quality Specifics:

• General Unsatisfactory Results: First, check that page size and media type settings match the loaded paper, both for copying/printing via the operation panel and for printing from a computer or smartphone using Canon PRINT Inkjet/SELPHY. Select a print quality setting appropriate for the paper and content; increasing it might improve blurring or uneven colors.
• Misaligned/Distorted Lines or Uneven Colors: If printouts have misaligned or distorted lines, or uneven colors, adjust the print head position. For Windows, if automatic alignment doesn’t work, you can perform manual print head alignment from the computer.
• Paper Smudges/Scratches: This can occur if the print head alignment sheet is dirty, or if the paper is curled. You can also adjust the “Ink Drying Wait Time” in Custom Settings via the Canon IJ Printer Assistant Tool (Windows) or Remote UI (macOS) to prevent smudging.
• Vertical Lines Next to Image: This might happen if the loaded paper is larger than the specified size, causing ink from automatic cleaning to get onto the paper. Ensure the paper size setting matches the loaded paper.
• Images Incomplete / Cannot Complete Printing: If printing stops mid-way, check the paper and print quality settings, and perform print head alignment.

5. Error Codes:

• The printer’s LCD and your computer screen will display support codes (error numbers) along with messages when errors occur.
• Support code 5100 indicates a printer error. Cancel printing, turn off the printer, and check if the FINE cartridges are properly installed and if anything is impeding the FINE cartridge holder’s motion. Avoid touching the clear film inside the printer. Then, turn the printer back on.
• Support code 6000 also indicates a printer error. Check for jammed paper, then turn the printer off and unplug it. After a while, plug it back in and turn it on.
• Other common codes like 1003 (no paper), 1200 (paper output cover open), 1203 (paper output cover opened during printing), 1250 (paper output tray closed), 1401 (FINE cartridge not installed), 1430 (FINE cartridge not recognized), 1485 (incompatible ink cartridge), and 1650/1651 (ink cartridge not recognized/communicating normally) have specific actions, often involving checking paper, closing covers, reinstalling cartridges, or pressing the Stop button for at least 5 seconds to disable ink level detection (for printing/copying/scanning/faxing with low/empty ink).

If the problem persists after trying these solutions, it is recommended to contact your nearest Canon service center for repair.
