PIXMA TR4720 Fixing Frequent Paper Jams and Print Quality Issues

[harmankandhari]

Hi Everyone,

I'm Harmandeep Singh Kandhari, Health and Wellness Motivator. Now, I want to know about what troubleshooting steps are recommended for resolving frequent paper jams and faded prints on a Canon PIXMA TR4720? Could this be related to driver updates, ink cartridge alignment, or roller maintenance?

Thanks,
Harmandeep Singh Kandhari

All the above. 

Fixing Frequent Paper Jams

Common Causes of Paper Jams

• Incorrect Paper Loading: Ensure paper is loaded correctly in the tray.
• Paper Type: Use suitable paper sizes; avoid A5 for documents with photos or graphics.
• Obstructions: Check for any foreign objects in the paper path.

Steps to Resolve Paper Jams

1. Check for Visible Jams: Open the paper output tray and check for jammed paper.
2. Remove Jammed Paper:
   • Pull out the jammed paper slowly to avoid tearing.
   • If not visible, check the feed slot and rear cover.
3. Restart the Printer: If the paper is stuck, turn off the printer, then turn it back on to see if it ejects automatically.

Improving Print Quality

Common Print Quality Issues

• Blank or Faint Prints: This may indicate low ink levels or clogged print heads.
• Blurry or Streaky Prints: Often caused by dirty print heads or incorrect paper settings.

Steps to Enhance Print Quality

1. Check Ink Levels: Ensure cartridges are not empty or improperly installed.
2. Clean Print Heads:
   • Print a nozzle check pattern.
   • If issues persist, perform a deep cleaning of the print heads.
3. Adjust Settings: Verify that the correct paper type is selected in the printer settings.

Hi Derrick,

It appears your response is the only authority found in the community related to paper jams.

I've had a similar problem with an older PIXMA MX420, where the paper drags to one side as it enters the printer's feeder, followed by an error message to clear the jam. I've tried all the above, even shaking the printer and looking inside it (as far as possible from the outside), but there doesn't seem to be any obstruction. I'm wondering if it is a roller issue that can be fixed, or if I should save the trouble and get a new one?

Thanks.

A new one, depends on whether your current printer can easily be repaired. I had a Brother printer, same issue, until it would not feed the paper at all. Could not fix the rollers and a new Canon printer was so cheap (until you buy ink!) that I bought one, and I chucked the Brother into the trash can.

Uneven paper feeding on a Canon PIXMA MX420 is usually caused by dirty or worn pickup rollers, a displaced roller, or paper that isn’t seated correctly.

1. Turn the printer off, unplug it, and remove the paper.
2. Check whether the pickup roller is still seated on both sides. If it has slipped off its shaft, don’t glue it; the retaining clip or roller assembly may need replacement.
3. Clean the rubber rollers with a lint-free cloth lightly dampened with water. Rotate the rollers by hand as you clean them. Let them dry completely.
4. Clean the paper path and the small separation pad beneath or near the pickup roller.
5. Reload a small stack of fresh, flat paper. Align the guides snugly against the paper without squeezing it, and avoid overfilling the tray.
6. Try feeding one sheet at a time. If it still pulls at an angle, test with another paper type or a new ream.
7. Run the printer’s roller-cleaning function if available: Setup → Maintenance → Roller Cleaning, then follow the display instructions.

If the roller is visibly loose, cracked, flattened, or turns unevenly, cleaning will not fix it. The pickup-roller assembly or separation pad likely needs replacement. If the paper enters straight but becomes crooked farther inside, look for a torn paper fragment or obstruction in the feed path.

Hi Derrick,

Thank you for replying. It is much appreciated.

It still doesn't work after attempting the cleaning. I'll admit it's not easy to reach the pickup roller. Perhaps it might need to be replaced.

Thanks for your help.

Kind regards,

Dominic
