Introduction
There’s nothing more frustrating than hitting print and watching your Canon Pixma MG7120 spit out completely blank pages—or worse, displaying an error code 1009 telling you there’s no paper in the cassette when you know you just filled it. If you’re experiencing this problem, you’re not alone. The good news? Most of the time, you can fix this yourself without calling a technician.
In this guide, we’ll walk you through exactly what causes these issues and how to troubleshoot them step-by-step. Whether your printer is printing blank pages or throwing that frustrating error code, we’ll help you get back to productive printing in no time.
Why Is Your Canon Pixma MG7120 Printing Blank Pages?
Before we jump into fixes, let’s understand what’s happening. When your printer produces blank pages, it usually means one of three things: your ink cartridges are empty or dried out, your print head is clogged, or there’s a software issue with your printer drivers. The MG7120 is an older model (discontinued in 2019), so it’s especially prone to ink cartridge drying if it hasn’t been used regularly.
Step-by-Step Troubleshooting for Blank Pages
Step 1: Check Your Ink Cartridges
This is the most common culprit, so start here:
- Power off your printer and wait 30 seconds
- Open the cartridge access door (usually on the right side of the printer)
- Visually inspect each cartridge for low ink levels or visible drying
- Remove each cartridge one at a time and look at the nozzles (the small holes at the bottom)
- If you see dried ink or residue, gently wipe the nozzles with a lint-free cloth slightly dampened with distilled water
- Reinstall the cartridges firmly until you hear a click
- Power the printer back on and try printing a test page
Pro tip: If your cartridges are low on ink, this is a good time to replace them. Genuine Canon cartridges work best with this model, though compatible cartridges are available if budget is a concern.
Step 2: Run the Nozzle Check and Print Head Cleaning
Your printer has built-in maintenance tools designed exactly for this problem:
- Access the printer’s menu on the control panel
- Navigate to Settings or Maintenance (exact menu names vary by firmware version)
- Select “Nozzle Check” and print the test pattern
- Examine the printed pattern for missing colors or lines
- If the pattern shows gaps, select “Print Head Cleaning” from the same menu
- Wait for the cleaning cycle to complete (this takes 2-3 minutes)
- Run the nozzle check again to see if the problem is resolved
- If gaps remain, run “Deep Cleaning” (this uses more ink but is more thorough)
You may need to repeat this process 2-3 times for severely clogged print heads. Be patient—this often works.
Step 3: Reset Your Printer
Sometimes a simple reset clears up software glitches causing blank pages:
- Power off the printer completely
- Unplug it from the electrical outlet
- Wait for 2-3 minutes (this clears the printer’s internal memory)
- Plug it back in and power it on
- Try printing a test page
Step 4: Update or Reinstall Your Printer Drivers
Outdated or corrupted drivers can cause your printer not to print correctly:
- Visit the Canon support website at canon.com
- Search for “Pixma MG7120” drivers
- Download the latest driver for your operating system (Windows or Mac)
- Uninstall the current printer driver from your computer’s settings
- Install the newly downloaded driver and restart your computer
- Try printing again
This often resolves mysterious blank page issues that cleaning doesn’t fix.
Fixing Error Code 1009: Paper Cassette Not Detected
Error 1009 means your printer isn’t recognizing the paper cassette. Here’s how to fix it:
Step 1: Remove and Reseat the Cassette
- Power off the printer
- Locate the paper cassette (usually the lower tray)
- Gently pull the cassette completely out of the printer
- Inspect the cassette for any torn paper, debris, or obstructions
- Check the cassette slot inside the printer for any visible jams or foreign objects
- Reinsert the cassette firmly until you hear it click into place
- Power the printer back on
Step 2: Check Your Paper
Sometimes the issue is the paper itself:
- Remove all paper from the cassette
- Fan the stack of paper to separate any stuck sheets
- Check that the paper is the correct size (usually 8.5″ x 11″ for standard printing)
- Ensure the paper isn’t wrinkled, bent, or damaged
- Reload the cassette with fresh paper, making sure it sits flat and doesn’t exceed the maximum fill line
- Adjust the paper guides on the sides of the cassette so they’re snug against the paper stack
Step 3: Clean the Paper Feed Rollers
Over time, dust and paper debris can accumulate on the rollers that feed paper:
- Power off and unplug the printer
- Open the cassette area
- Locate the small rubber rollers inside the paper feed mechanism
- Dampen a lint-free cloth with distilled water (not soaking wet)
- Gently wipe the rollers to remove dust and debris
- Let everything dry completely before reassembling
- Plug in and power on the printer
Step 4: Check for Jammed Paper
Even small pieces of torn paper can trigger error 1009:
- Power off the printer
- Open all access panels and doors
- Look carefully inside the paper path for any torn pieces or debris
- Use a flashlight if needed to see into dark areas
- Gently remove any obstructions (never force anything)
- Close all panels and power back on
Preventative Tips to Avoid These Problems
Now that you’ve fixed the issue, here’s how to prevent it from happening again:
- Use your printer regularly – Even if you don’t print often, run a test page every week or two to keep the print head from drying out
- Store paper properly – Keep paper in a cool, dry place in its original ream to prevent moisture absorption
- Use quality paper – Cheap paper can leave more debris in the feed mechanism
- Replace cartridges promptly – Don’t let them run completely dry; this damages the print head
- Keep the printer clean – Dust accumulation can cause feed problems; gently wipe the exterior monthly
- Avoid overfilling the cassette – Stick to the maximum fill line to prevent jams
When to Call a Professional
If you’ve tried all these steps and your Canon Pixma MG7120 is still printing blank pages or showing error 1009, it may be time to consider professional service. The print head may be permanently damaged, or the cassette sensor could be faulty. Given that this model is discontinued, parts may be hard to find, and repair costs might exceed the price of a new printer.
However, before you give up, try one more thing: contact Canon support directly. They sometimes have additional troubleshooting steps specific to your printer’s firmware version.
Final Thoughts
Most printer problems—including blank pages and error 1009—are fixable with a little patience and the right approach. By following these steps, you’ve empowered yourself to solve the problem without expensive service calls. Remember, regular maintenance and proper paper handling go a long way toward keeping your printer running smoothly.
Happy printing!
