Unveiling Solutions: Troubleshooting Canon PIXMA MG 5550 Printing Issues and PGBK Ink Tank Problems

Canon PIXMA MG 5550 users are reporting a frustrating issue where the PGBK (Pigment Black) section fails to print, resulting in fuzzy prints and doubled text. Despite attempts at maintenance, including cleaning, deep cleaning, roller cleaning, and bottom cleaning, the problem persists even after replacing all cartridges with original Canon ones. Seeking a solution, a user with a PIXMA MG 6250, an older model, suggests a unique approach involving removing and cleaning the print head under hot running water. This article explores this problem and provides a step-by-step guide on potential solutions.

Problem Analysis

The reported issue of the PIXMA MG 5550 failing to print from the PGBK ink tank indicates a potential problem with the print head or ink delivery system. The user has already attempted standard troubleshooting steps such as cleaning, deep cleaning, and cartridge replacement without success.

Troubleshooting Steps

1. Print Head Cleaning

• Before resorting to more drastic measures, ensure the print head is clean. Use the printer's built-in cleaning functions to clear any clogs or dried ink.

2. Head Alignment

• Run a head alignment process to ensure proper positioning of the print head. Misalignment can lead to print quality issues.

3. Nozzle Check Pattern

• Print a nozzle check pattern to identify which sections are not printing correctly. This information helps pinpoint the specific area of concern.

4. Printer Head Removal and Cleaning

• If the issue persists, consider the method suggested by the PIXMA MG 6250 user. Remove the cartridges, lift the printer head clip, and take out the print head. Rinse the print head under hot running water, ensuring water trickles out of each inkjet for about two minutes. Thoroughly dry the print head with absorbent kitchen roll and reassemble the printer.

5. Caution

• Exercise caution when removing and cleaning the print head, as it involves potential risks. Refer to available YouTube videos for visual guidance.

Potential Risks

While the PIXMA MG 6250 user's method offers a solution, it comes with potential risks. Cleaning the print head under running water may cause damage if not done carefully. Users attempting this method should be aware of the associated risks and proceed at their own discretion.

Alternative Solutions

If the suggested method proves unsuccessful or if users are uncomfortable with the risks involved, another option is consulting Canon customer support or visiting an authorized service center. A malfunctioning print head may require professional attention or replacement.
