When your Canon PIXMA TR150 printhead clogged issue appears, you'll notice faded prints, streaking, missing colors, or completely blank pages despite full ink tanks. This compact mobile printer uses a thermal inkjet system with a fixed printhead assembly that can dry out during travel, infrequent use, or after cartridge changes. As printer repair specialists, we've restored hundreds of TR150 units—here's our complete troubleshooting guide to fix printer output problems without unnecessary service calls.
Initial Diagnosis: Confirming Printhead Clogs
Before attempting deep cleaning, verify that a clogged printhead is actually your problem rather than empty cartridges, electrical faults, or software errors. Run the built-in nozzle check from your printer's maintenance menu or Canon PRINT app. A healthy Canon PIXMA TR150 printhead clogged situation will show gaps or missing segments in the test pattern, typically in cyan, magenta, yellow, or black channels.
1
Run Automated Printhead Cleaning: Access your TR150's maintenance settings through the Canon PRINT Inkjet/SELPHY app or Windows printer properties. Navigate to Device Settings > Maintenance > Cleaning, then execute one standard cleaning cycle. Print a nozzle check immediately after—do not run multiple cleanings back-to-back, as this wastes ink and can actually worsen clogs by pushing dried pigment deeper into the nozzles.
2
Perform Deep Cleaning if Needed: If the standard cycle doesn't resolve your Canon PIXMA TR150 printhead clogged problem, run one Deep Cleaning cycle from the same maintenance menu. This uses significantly more ink but applies stronger pressure pulses to dislodge stubborn blockages. The TR150's PG-245/CL-246 or PG-245XL/CL-246XL cartridges must have adequate ink remaining—deep cleaning with low cartridges can introduce air bubbles that compound the problem.
3
Manual Printhead Flush with Distilled Water: For severe clogs, power off and unplug the printer. Remove both cartridges, then place a folded paper towel soaked in warm distilled water (never tap water—minerals damage nozzles) beneath the printhead parking position. Manually slide the printhead carrier to center if possible, or leave it parked if not. Let the moisture wick upward for 15-20 minutes to dissolve dried ink. This printer support technique works particularly well for pigment-based black ink that crystallizes in the TR150's fine nozzles.
4
Use Canon's Printhead Cleaning Solution: Purchase Canon-approved printhead cleaning solution or a quality third-party equivalent formulated for thermal inkjet heads. Apply 2-3 drops directly to the printhead contact surface using a lint-free swab, let it sit for 10 minutes, then run one standard cleaning cycle. This targeted approach often succeeds where automated cycles fail on the Canon PIXMA TR150 printhead clogged scenarios involving complete color dropout.
5
Implement Preventative Maintenance Schedule: Once resolved, prevent recurrence by printing at least once weekly, even a small test page. Enable the TR150's automatic printhead maintenance in the driver settings, and always power down using the printer's button rather than unplugging—which leaves the printhead uncapped and exposed to drying. For mobile users, transport the printer with cartridges installed and padding to prevent vibration damage to the delicate nozzle plate.
6
Replace Cartridges and Reset: Old or refilled cartridges can cause false clog symptoms. Install genuine Canon PG-245/CL-246 cartridges, then perform a full reset: hold the Resume button for 10 seconds with power on until the alarm light flashes. Re-run nozzle check to confirm all channels fire properly. If troubleshooting steps 1-5 haven't restored output, the printhead assembly itself may require professional printer repair or replacement.
⚠️ Important: Never use rubbing alcohol, ammonia-based cleaners, or compressed air on your Canon PIXMA TR150 printhead—alcohol degrades the plastic manifold seals, and compressed air can rupture the microscopic thermal resistors that fire ink droplets. Always power down and disconnect AC power before any manual cleaning to prevent electrical damage or ink system pressurization faults.
When to Seek Professional Tech Support
If you've completed all six troubleshooting steps without success, your TR150 may have a physically damaged printhead, failed flex cable, or mainboard driver issue. The TR150's printhead is technically user-replaceable (part QY6-0086 compatible), but the procedure requires disassembly of the compact chassis. For units under warranty, Canon's tech support covers printhead defects—contact them before attempting replacement. Out-of-warranty units often benefit from professional fix printer services that can source genuine parts and guarantee calibration afterward.
Frequently Asked Questions
How do I know if my Canon PIXMA TR150 printhead is clogged versus just out of ink?
Check your ink levels in the Canon PRINT app first. If levels show adequate but nozzle check patterns have gaps or missing colors, you have a genuine clog. Empty cartridges typically produce completely blank pages or specific "ink out" error codes on the status monitor.
Can I prevent my TR150 printhead from clogging during long storage?
Yes—print a test page every 7-10 days minimum, or use Canon's periodic cleaning schedule in the Windows driver (Preferences > Maintenance > Custom Settings). For storage beyond one month, remove cartridges, seal them in original clips, and power down the printer properly so the cap station seals the printhead.
Why does my TR150 printhead clog more often than my desktop Canon printer?
The TR150's compact mobile design prioritizes portability over robust maintenance systems. Its smaller cap station evaporates faster, travel vibration can dry nozzles, and temperature fluctuations in briefcases or vehicles accelerate ink dehydration. Regular use is the most effective prevention.
