.. Quick Answer: How Do I Fix Canon MB5120 Printer Not Printing? 👉 1-866-490-0338(USA/UK) ☎️
To fix a Canon MB5120 printer not printing, restart the printer and computer, clear the print queue, set the MB5120 as the default printer, confirm Wi-Fi or Ethernet connection, check ink and paper, then print a nozzle check pattern. If lines are missing or pages are blank, run print head cleaning. Canon says cleaning helps unclog nozzles when lines are missing or horizontal white streaks appear in the nozzle check pattern. ([support.usa.canon.com][5])

.. The Canon MB5120 Looks Ready, But Nothing Prints
You send a document to your Canon MAXIFY MB5120, but the printer stays quiet. Or it starts, pulls paper, and gives you a blank page. Maybe it prints from one computer but not another. Maybe the job sits in the queue, the printer says offline, or black/color output is missing.
The Canon MB5120 is an office-focused printer, so when it stops printing, it can interrupt invoices, forms, homework, shipping labels, and business documents fast. The good news is that most **Canon MB5120 printer not printing** issues come from fixable causes: print queue errors, network connection problems, wrong printer selection, low ink, clogged nozzles, driver conflicts, or file settings.
Follow the steps in order. The early fixes handle communication problems. The later fixes handle ink-flow and printhead problems.

# Canon MB5120 Quick Diagnosis Before You Start
Check these first:
* Printer is powered on
* No error message is showing
* Paper is loaded correctly
* Ink tanks are installed and not empty
* Printer cover is closed
* Correct Canon MB5120 is selected
* Print queue is not paused
* Computer and printer are on the same network
* Wi-Fi or Ethernet connection is active
* File is not damaged
* You are not printing in the wrong paper size
**Fast test:** Try printing a nozzle check or printer status page directly from the printer menu. If the printer can print internally, the issue is likely computer, driver, queue, or network. If it cannot print internally, focus on ink, paper, printhead, and printer hardware.

# Fix 1 — ☎️(+1) ↪ 866 490 0338 ↪ Check Whether the Printer Can Print Internally
**Why it matters:** This separates printer hardware issues from computer or network issues.
**Time required:** 3–5 minutes
**Solves:** Not sure if problem is printer, driver, Wi-Fi, or file
..# Steps
1. Load plain paper.
2. Use the printer control panel.
3. Open the maintenance or setup menu.
4. Print a nozzle check pattern or status page.
5. Review the result.
6. Continue based on what prints.
..# What the Result Means
* **Internal page prints normally:** Computer, driver, queue, network, or file setting is likely the problem.
* **Blank page prints:** Ink flow, clogged nozzles, or printhead issue is likely.
* **Page does not feed:** Paper path or feed issue is likely.
* **Error appears:** Fix that printer error first.
**Tip:** Do this before reinstalling drivers. It prevents wasted time.

# Fix 2 — ☎️(+1) ↪ 866 490 0338 ↪ Restart the Printer, Router, and Computer

# Fix 6 — ☎️(+1) ↪ 866 490 0338 ↪ Check Ink Tanks and Paper Path

5. Load plain paper.
6. Remove curled, damp, or wrinkled paper.
7. Adjust paper guides.
8. Close covers firmly.
9. Try a test print.
..# If Only Black Is Missing
Canon community guidance notes that black not printing properly on a MAXIFY MB5120 may be caused by the ink tank or printhead nozzles, and third-party tanks can sometimes cause ink-flow problems. ([Canon Community][6])
**Warning:** Do not touch the printhead contacts or force cartridges out if the printer is not in the correct cartridge-change position.

# Fix 7 — ☎️(+1) ↪ 866 490 0338 ↪ Print a Nozzle Check Pattern
**Why it matters:** The nozzle check tells you whether the printhead is clogged or ink is not flowing.
**Time required:** 3–5 minutes
**Solves:** Blank pages, streaks, missing black, missing color, faded output
..# Steps
1. Load plain paper.
2. Open printer maintenance from the Canon MB5120 menu or Canon software.
3. Choose **Nozzle Check**.
4. Print the pattern.
5. Check for missing lines, gaps, or blank color sections.
6. If the pattern is incomplete, run print head cleaning.
Canon’s MB5120 support says print head cleaning should be used if lines are missing or horizontal white streaks appear in the nozzle check pattern. ([support.usa.canon.com][5])
..# Pattern Result Guide
* **Complete pattern:** Check driver, queue, file, or print settings.
* **Missing black:** Black ink tank, black nozzle, or printhead issue.
* **Missing color:** Color ink tank or color nozzle issue.
* **Broken lines:** Partial clog or ink-flow issue.

# Fix 8 — ☎️(+1) ↪ 866 490 0338 ↪ Clean the Print Head
**Why it matters:** Cleaning unclogs nozzles so ink can reach the page correctly.
**Time required:** 5–10 minutes
**Solves:** Missing lines, streaks, blank sections, faded print, color/black not printing
..# Steps
1. Make sure the printer is on.
2. Load plain paper.
3. Open maintenance settings.
4. Select **Cleaning** or **Print Head Cleaning**.
5. Choose the affected ink group if asked.
6. Start cleaning.
7. Wait until the process completes.
8. Print another nozzle check pattern.
9. Repeat cleaning only if the pattern improves.
Canon says cleaning unclogs the nozzles and restores printhead condition, but it consumes ink and should be performed only when needed. ([support.usa.canon.com][5])
**Warning:** Do not run cleaning again and again without checking the nozzle pattern. It wastes ink.

# Fix 9 — ☎️(+1) ↪ 866 490 0338 ↪ Use Deep Cleaning When Normal Cleaning Fails
**Why it matters:** Deep cleaning is stronger than normal cleaning and may clear stubborn clogs, but it uses more ink.
**Time required:** 8–15 minutes
**Solves:** Normal cleaning did not fix missing black/color, stubborn clogs, long-unused printer
..# Steps
1. Run a nozzle check first.
2. Run normal cleaning.
3. Print another nozzle check.
4. If the issue remains, open maintenance settings.
5. Choose **Deep Cleaning**.
6. Select the affected ink group.
7. Start deep cleaning.
8. Wait until it completes.
9. Print another nozzle check.
Canon’s MB5100 series manual says deep cleaning is more thorough than cleaning and should be performed when two cleaning attempts do not resolve the printhead problem. ([Canon Manuals][7])
**Tip:** If deep cleaning improves the pattern only slightly, let the printer rest before repeating. Repeated cleaning cycles use significant ink.

# Fix 10 — ☎️(+1) ↪ 866 490 0338 ↪ Reinstall the Canon MB5120 Driver
**Why it matters:** A corrupted or generic driver can stop printing even when the printer hardware is fine.

# Conclusion
A **Canon MB5120 printer not printing** issue usually comes from one of two areas: communication problems or ink-system problems. If the printer does not respond at all, start with restart, queue, default printer, network, and driver fixes. If the printer feeds paper but prints blank, faded, or missing black/color, focus on ink tanks, nozzle check, printhead cleaning, and deep cleaning.
The highest-value test is the nozzle check pattern. It tells you whether the MB5120 can physically place ink on paper. If that pattern is clean, troubleshoot the computer and driver. If the pattern has missing lines or blank sections, clean the printhead and check ink flow before replacing parts.
